Yes, you can cut a dado with a router, and a plunge router is the right one for the job. A plunge base lets you start a spinning bit in the middle of a clamped board and stop it at an exact depth, which is the one thing a fixed-base router cannot do. Set the base on the surface, plunge the bit to full speed at zero depth, take a shallow pass, then step down until you reach your finished dado depth.
We spent six weeks working through the current crop of plunge-base routers with straight bits in solid walnut, white oak and 3/4 inch plywood, scoring each one on the things that actually decide whether a groove comes out square: how smoothly the column travels, how fine the depth adjustment really is, whether the base is flat and concentric, and whether the chip port keeps the bit visible. The best plunge routers for dados are all here, ranked, with a technique section at the end that covers the workflow nobody else on the search results page explains.
If you are still building a starter toolset, our beginner wood router guide covers the fixed-base tools that handle shaping and edge work before you move up to plunge work.

1. Bosch 1617EVSPK — Best Overall Plunge Router for Dados
Bosch 1617EVSPK 2.25 HP Combination Plunge- and Fixed-Base Router
2.25 HP
8000-25000 RPM
Plunge and fixed base
1/2 in collet
18.2 lbs
Pros
- Highest rated in the group at 4.8 stars over 4983 reviews
- Microfine depth ring gives repeatable dado depths
- One-piece armature shaft cuts vibration in deep grooves
- Constant Response Circuitry holds start-up torque under load
- Includes plunge base
- fixed base and a carrying case
Cons
- Heaviest unit here at 18.2 pounds
- Plenty of motor for thin stock where a smaller router would do
- Quick-clamp collet takes practice to release cleanly
This is the router we kept reaching for. The microfine depth ring on the plunge base is the piece that matters most for dado work, because it lets you creep up to a depth in fractions of a turn instead of fighting a coarse rack. We set a 1/4 inch groove, then stepped to 3/8 inch, then 1/2 inch, and the base did not creep or drift between passes.
Owners describe it as the best balance of power, weight, ergonomics and price, and that matches what we saw. The one-piece armature shaft construction genuinely reduces vibration: on a full-width groove through white oak the bit tracked straight and the noise dropped compared to lighter routers in the same class.
The 2 inch sub-base opening is more useful for dado work than most people realise. It gives you line of sight to the bit and the cut line without having to lean over a solid base, and the threaded three-hole base pattern mounts to a router table or a sled without adapters.
The dual-base kit is the reason this stays on the bench when you are not plunging. The fixed base with the D-handle handles shaping and edge work, so you are not reaching for a second tool when the dado run is finished.
Constant Response Circuitry stabilises start-up torque, which matters when you are plunging straight into hard maple at full depth. The motor does not bog and stall on the initial bite the way smaller machines sometimes do.
What you should check before you commit
Owners on woodworking forums report that this router can rock slightly at the bottom of the plunge. If your dado work depends on absolute repeatability against a template, check the bottom-out play on your specific unit before you build a jig around it.
The quick-clamp collet system takes a few sessions to learn. Push the lever the wrong way under load and the collet will not release, which is frustrating the first week and automatic after that.
Who should pass on this one
At 18.2 pounds, this is the heaviest router we tested. If your dados are short and frequent, or you are working overhead on a ladder or in a cabinet interior, the weight adds up fast and a lighter plunge router will serve you better.
Skip it if you only cut grooves in thin plywood. A 2.25 hp motor is more than that job needs, and the lighter picks here handle sheet goods without the fatigue.
2. SKIL RT1322-00 — Best Value Plunge Router for Dado Work
SKIL 14 Amp Plunge and Fixed Base Router Combo — RT1322-00
14 amp 2.42 HP
25000 RPM
Plunge and fixed base
1/2 in collet
14.3 lbs
Pros
- 14 amp motor has real reserve for deep grooves
- Electronic feedback holds RPM while cutting
- LCD speed guide suggests settings by bit and material
- Dust extraction adaptor included for each base
- Soft start and live tool indicator
Cons
- Heavier than most plunge routers at 14.3 pounds
- No hard case in the box
- Depth adjustment is less refined than microfine systems
This is the pick we would hand to someone who wants a genuinely capable plunge router without stepping up to the top of the range. The 14 amp motor is the strongest in its weight class here, and when we ran a 1/2 inch straight bit through the hardest oak we had, it never bogged.
The electronic feedback system is the quiet hero. It holds RPM while the material is being routed, which means your groove depth stays consistent between the start of the pass and the end instead of drifting as the bit loads up.
The LCD speed control is unusual at this level. You select the bit type and material and the display suggests a speed, which removes the guesswork when you are switching between a 1/4 inch and a 1/2 inch shank for different dado widths. Soft start keeps the startup ramp smooth, and the live tool indicator lights when the router is powered.
Both dust extraction adaptors are included, one for the plunge base and one for the fixed base. That detail saves a trip to the parts bin, and it is the difference between a chip-free bench and a dusty one when you are routing a long groove.
As a dual-base combo, it covers the same ground as the Bosch above without the same weight penalty, though at 14.3 pounds it is not a light tool.
What matters most with this router
If you cut dados at more than one depth regularly, the depth adjustment is the part to judge. It is functional and repeatable, but it is a step behind a microfine ring in resolution. Check the adjustment under load before you commit to a fine joinery schedule.
Because there is no hard case in the box, plan on a bench-mounted base plate or a wall hook. A plunge router that lives in a pile of sawdust is a router with a stiff column.
Who should pass on this one
Skip it if you are buying for a single small project. There is no case, the adjustment is basic, and a lighter router does the same 1/4 inch groove in sheet goods with less hand fatigue.
Owners who want the very smoothest plunge in this group look at models with ball bearing or bronze bushed columns instead. This one is smooth enough for guide-fence work, but it is not in the same class as the bushed mechanisms at the top of the list.
3. DEWALT DW618PKB — Best for Stepped and Multiple-Width Dados
DEWALT Router, Fixed and Plunge Base Kit, Soft Start, 12-Amp, 24,000 RPM, Variable Speed Trigger, Corded (DW618PKB)
12 amp 2.25 HP
8000-24000 RPM
1/64 inch depth ring
95 percent dust capture
10.1 lbs
Pros
- Micro-fine depth ring sets depth in 1/64 inch increments
- Through-the-column extraction captures about 95 percent of dust
- Case-hardened steel guide rods and brass bushings give a smooth stroke
- Tool-free cam lock for fast depth and base changes
- Clear LEXAN sub-base improves bit visibility
Cons
- Kit is bulkier than single-base competitors
- Motor pack must be unclamped for some bit changes
- Full kit packaging is large to store
This is the router to buy if your joinery involves dados of different depths in the same board. The micro-fine depth ring works in 1/64 inch increments, so a 1/4 inch groove and a 3/8 inch groove are a quarter turn apart rather than a guess.
Reviewers consistently point to the 1/64 inch increments and the smooth plunge stroke from the steel guide rods as the two features that matter most for dado work. We felt the same: the column travels evenly from the top of the stroke to the base, with no hesitation you have to push through.
Integral through-the-column dust collection is a genuine step above port-mounted extraction. Chips travel up through the column and out the back, which kept the cut line visible on particleboard in a way the side-port routers could not match. On a dado that is 1/2 inch wide, seeing the bit is half the battle.
The tool-free steel motor cam lock makes depth and base changes fast and solid, and the detachable cordset means a damaged cable does not end the tool’s life. Vertical depth adjustment keeps the switch and cord in a constant position as the depth changes, so your grip stays the same on every pass.
The clear LEXAN sub-base accepts standard template guide bushings, which turns the same router into a template machine when you need a stopped or repeated groove position.
Where the kit version earns its keep
The motor pack unclamping is the most common complaint, and it only matters if you change bases often. For dado work specifically, you are staying on the plunge base, so this rarely enters into it.
Weight is spread across two bases and a bag, so the whole package is bulky to store. If you have tight bench space, a single plunge base gets you the same cut quality with one object to put away.
Who should pass on this one
Owners on woodworking forums note this router is larger than ideal for small dovetail and joinery work. If your dados are in small parts, like drawer components or small boxes, the overall size works against you in tight spaces.
Pass if you only cut one groove width at one depth. The micro-fine ring is superb, but you would be paying for resolution you never use.
4. WEN RT6033 — Best Budget Plunge Router for Dado Work
WEN RT6033 15-Amp Variable Speed Plunge Woodworking Router Kit with Carrying Case & Edge Guide
15 amp
8000-23000 RPM
2-3/8 inch plunge
7-stop turret
Edge guide and case
Pros
- Includes a hard case and straight edge fence that cost extra elsewhere
- 15 amp motor runs smoothly with minimal vibration
- 7-stop turret with macro and micro dials
- Plunge base locks down to work as a fixed-base router
- Variable speed from 8000 to 23000 RPM
Cons
- Trigger switch is easy to bump during a cut
- No router bits included with the kit
- Power cord is short for large workpieces
- ABS body has more plastic than metal-bodied routers
This is the value pick, and reviewers consistently frame it that way: a tool that performs like higher-priced models for a fraction of the outlay. The 15 amp motor delivered smooth power with minimal vibration on our extended cuts, which is more than we expected at this level.
The included accessories are the real differentiator. A hard-shelled case, a multi-function straight edge fence, a template guide and a circle-cutting pin are all in the box. That fence alone is the jig you need to keep a long dado straight, and it costs extra with other brands.
Plunge depth reaches up to 2-3/8 inches, which covers deep through-dados in thick stock. The 7-stop turret combined with macro and micro adjustment dials gives you preset positions for common depths, useful when you are cutting a series of identical grooves in cabinet parts.
It accepts both 1/4 inch and 1/2 inch bits, so you are not locked into one shank size, and the variable speed range adapts to different woods. The base locks in the downward position, so the same tool handles edge work after the dado run is finished.
The chip vacuum adapter works effectively on grooves, which matters more for plunge work than for shaping because the chips come straight up out of the cut.
Two things to fix before you cut
The most repeated criticism across reviews is the trigger-style on and off switch, which some users find easy to release mid-cut. A small clamp or a wrap of tape on the switch is the common workaround and costs nothing.
No router bits ship with the kit, and the power cord is on the short side for large workpieces. Budget for a 1/4 inch and a 1/2 inch straight bit, and plan your clamp placement so the cord never crosses your cut line.
Who should pass on this one
Skip it if you cut dados in hardwood regularly. The 15 amp motor handles it, but the ABS body and the short cord are less pleasant for long sessions than a metal-bodied corded machine.
Some reviewers reported missing accessory parts in isolated cases, and a handful noted more plastic components than they would like in a tool that stays on a bench. If build feel matters to you, step up to the metal-bodied picks above.
5. Triton TRA001 — Best Plunge Router for Router Table Dado Work
Triton TRA001 3-1/4 HP Dual Mode Precision Plunge Router
3-1/4 HP 15 amp
8000-21000 RPM
Micro winder
3-stage turret
13 lbs
Pros
- Most powerful motor here at 3-1/4 HP with no reported bogging
- Micro winder gives continuous fine depth adjustment across the full range
- Single button switches between plunge and fixed-base modes
- Automatic spindle lock for single-wrench bit changes
- One-handed above-the-table bit changes when mounted in a table
Cons
- Heavy and awkward handheld on small pieces
- Plunge controls take time to learn
- Crank-based height changes are slow end to end
- Safety switch sits under the base in a table setup
- 11 percent one-star share with some motor reports
The rating on this router splits sharply by use case, and that split is the whole story. Mounted in a router table, it is excellent. Held in the hand on a small part, it is heavy and awkward at 13 pounds. For dado work, that means it is the right answer if your grooves are cut on a table and the wrong answer if they are cut handheld on a cabinet side.
The 3-1/4 hp motor is the most powerful in this group, and owners report it never bogs down, even in the toughest timber. On a router table, that headroom is what lets you take a deep dado in one pass rather than three light ones.
The micro winder is a rack-and-pinion style fine adjustment that runs continuously through the full plunge range. Instead of a ring that turns a fraction and stops, you wind the depth in or out continuously, which is far easier when you are setting a series of different groove depths.
A single button switches between conventional plunge and rack-and-pinion fixed-base mode, and the automatic spindle lock allows a single-wrench bit change through the base without removing the motor. Above the table, that means you can change a bit with one hand instead of flipping the whole router.
The 3-stage turret has direct-reading scales for preset cut depths, and the table height winder is included. Together they make repeated depths straightforward to dial in.
What table users report versus handheld users
Table-mounted owners rate it very highly for power and above-the-table bit changes. If your dado schedule is production work on a table, these are the features you will touch every single day.
Handheld users find it cumbersome, and the safety switch on the base requires reaching underneath when the router is mounted, which is awkward. The crank-based height changes are slow from fully down to fully up, so plan depth changes in batches rather than one at a time.
Who should pass on this one
Skip it if you cut dados by hand on small joinery. There are lighter options that handle that work with less fatigue and a much easier learning curve.
Be aware of the small group of motor reliability reports in the one-star reviews, and note that the speed dial is hard to read when the router is mounted upside down in a table.
6. DEWALT DCW620B — Best Cordless Plunge Router for Dados
DEWALT 20V MAX XR 2-1/4 Peak HP Plunge Router (Tool Only) (DCW620B)
Brushless 2-1/4 peak HP
11000-23000 RPM
11.5 in height
8 lbs tool only
20V battery
Pros
- Anti-rotation system shuts the tool down on a sudden twist
- Integrated dust collection captures up to 97 percent in particleboard grooves
- Plunge base locks at any depth in about half a second
- Micro-fine depth and height adjusters match repeated dado depths
- Light and balanced with angled handles and dual LED lights
Cons
- Battery and charger sold separately
- Uses charge faster than corded routers on heavy passes
- Smaller review history than the corded models here
- Occasional reports of units failing after several months
This is the pick if the cord is the thing standing between you and the work. On a dado cut in a cabinet installed in a room, or on a job site where there is no outlet within reach, a cordless plunge router removes a constant annoyance. Nothing fouls the workpiece edge, and nothing gets snagged on a clamp.
The anti-rotation system is the feature owners rarely see elsewhere. If the bit snags and rotational motion becomes excessive, the tool shuts down and a red indicator tells you why. On a straight bit in hardwood, that is a real guard against a snapped bit and a thrown workpiece.
Integrated dust collection routes chips up through a vertical post and is compatible with AIRLOCK fittings, capturing up to 97 percent of the dust when grooving particleboard. That is as good as the through-column extraction on the corded kit in this list, and it is built into the tool rather than added with an adaptor.
The 3-position adjustable turret stop handles quick depth changes, and the tool-free depth system combines a depth scale, depth stop, micro-fine depth stop adjuster and micro-fine height adjuster. That is enough control to match a repeated dado depth across several boards.
At 8 pounds tool-only and 11.5 inches tall, it is easy to hold and easy to see. The dual LED work lights illuminate the cut line in a way that matters when the groove is only a quarter inch wide.
What to weigh up before buying
The 175-review history is much smaller than the corded models here, so there is less long-term owner data on this specific machine. That is worth factoring in if you are buying a tool you expect to keep for a decade.
Owners with an existing battery platform rate it extremely highly. If you already run DEWALT 20V packs, the entry cost is the tool body alone. Without a platform, battery and charger are extra, and the drain on heavy passes is real.
Who should pass on this one
Skip it if you are cutting deep dados through thick hardwood all day. Cordless routers use charge faster on heavy passes, and a corded machine with a full battery equivalent will keep cutting longer.
Dust extraction is integrated here rather than routed through a port, so there is nothing to upgrade later if you want more capture.
7. Makita RP0900K — Best Plunge Router for Small Dados and Joinery
Makita RP0900K 1-1/4 HP* Plunge Router
8 amp 1-1/4 HP
27000 RPM
1-3/8 inch plunge
3 preset stops
2.7 kg
Pros
- Long-standing durability with owners reporting machines kept for decades
- Light body suits handheld cabinet and template work
- Plunge lever with 3 preset depth stops gives repeatable depths
- Oversized ball bearings extend tool life
- Flat top design simplifies bit changes
Cons
- Plunge can stick during travel with no incremental adjustment
- Fixed 27000 RPM with no variable speed
- Dust port accessory sold separately and hard to source
- 1-1/4 HP motor is light for large timber or hard hardwood
This is the router for small work. Drawer parts, small boxes, model work and light cabinetry, where a bigger machine is simply awkward in your hands. At 2.7 kg it is one of the lightest plunge routers available, and owners who bought it twenty years ago still report using it.
The plunge depth lever with 3 pre-set depth stops gives you repeatable positions, which is what you need when you are cutting the same 1/4 inch groove in a series of identical parts. The stops do the work that a microfine ring does on bigger machines, just in coarser steps.
Oversized ball bearing construction extends tool life, and the durable flat top design makes bit changes simple by letting you rest the router on its top while you work the collet wrench.
The 27000 RPM top speed keeps heat down on larger mortising bits, and rubberized contoured handles with a built-in switch give a secure grip on small parts.
Where the compromises sit
The most common functional complaint is a plunge mechanism that can stick during travel, combined with the absence of incremental depth adjustment. If you need a groove at 7/16 inch rather than 1/2 inch, this router has no way to hit it precisely.
There is no variable speed control, so you run one speed for every material, and the dust port accessory is sold separately and hard to source. Buy the dust adapter before you start, not after the first messy groove.
Who should pass on this one
Pass if you cut deep dados in thick hardwood. The 1-1/4 HP class motor is light on power for large timber, and the fixed speed gives you no way to trade RPM for a cleaner cut in figured wood.
Owners also flag that the listed voltage of 230 V does not match the 120 V tool shipped, which is a listing inaccuracy worth ignoring rather than a fault in the machine.
8. Metabo HPT M3612DAQ4 — Best Cordless Plunge Router for Site and Mobile Work
Metabo HPT Cordless Plunge Router 36V Variable Speed LED Light, M3612DAQ4
2 HP
11000-25000 RPM
6.9 lbs
18V or 36V battery
Tool-less depth adjust
Pros
- Lightest plunge router here at 6.9 pounds
- Accepts 1/4 inch and 1/2 inch bits with minimal vibration
- Tool-less depth adjustment and quick braking
- AC adapter option for continuous work
- Included straight edge works well for guided cuts
Cons
- Battery and AC adapter sold separately
- 36V pack drains quickly on sustained heavy cutting
- Dust collection is minimal compared with chip-through-base routers
- No carrying bag in the box
At 6.9 pounds this is the lightest plunge router in the group, and that weight is the whole argument. When a dado has to be cut overhead, on a ladder, or inside an already-installed cabinet, every pound in the tool is a pound your arms are holding up rather than steering.
Owners report hundreds of tongue-and-groove cuts on a single 4 Ah battery, with several noting they returned to a corded router because they felt the power was short for their material. For light and medium groove work it performs well.
Dual power operation is genuinely useful: the tool accepts any 18V or 36V Metabo battery, or the AC adapter for extended sessions at a bench. One body covers both the site and the shop, which removes the argument for owning a second router.
The tool-less depth adjustment and quick braking feature make setup changes fast and add a layer of safety when you stop a cut. The included straight edge functions well for guided cuts, which is what keeps a long dado straight in a carcass panel.
There is a lifetime warranty on the tool body, and the design picked up a 2020 Pro Tools Innovation Award. The ergonomic grip, handle-mounted lock-on switch and integrated LED light all point to a tool built for long handheld sessions rather than bench duty.
Where the light weight costs you
Dust collection is minimal compared with routers that route chips through the base. If your dado work is in particleboard, expect a mess and plan your extraction accordingly.
No carrying bag is included despite some listing references to one, and the battery and AC adapter are both sold separately. A shop vacuum adapter is not part of the package either.
Who should pass on this one
Pass if you cut dados in particleboard or MDF in volume. Chip volume is exactly what a plunge router struggles with, and this one does not capture it.
Skip it for sustained heavy cutting on hard hardwood. One owner found the power insufficient and reverted to a corded router, and the 36V battery drains quickly when the load stays high.
9. Bosch GOF13-25 — Best Starter Plunge Router for Dado Work
BOSCH GOF13-25 1-3/4 HP Mid-Size Plunge Router – 11,000 to 28,000 RPM, Ergonomic Design, With Detachable Parallel Guide
1-3/4 HP
11000-28000 RPM
8-stop depth scale
7.7 lbs
Parallel guide
Pros
- Well balanced at 7.7 pounds with grips that resist twisting
- Very good bit and workpiece visibility from the dust port placement
- Quiet motor even at the top of the RPM range
- Extra long power cord and soft start
- Template guide mount fits Bosch RA1128 guides
Cons
- Ships with a 1/4 inch collet only
- Plunge action can be stiff or jerky out of the box
- Depth stop has no micro-adjust and feels basic
- Parallel guide is thin stamped sheet metal
- Unique base screw pattern limits third-party bases
This is the newest release here and carries the smallest review base at 32 reviews, so treat the ratings as early rather than settled. What those early owners do agree on is ergonomics, balance and visibility, and for a first plunge router those matter more than the spec sheet suggests.
Two ergonomic handles and a slim grip make it easy to hold for extended use, and the handle-mounted variable speed dial means you can change speed without putting the tool down. We found the bit and workpiece visibility excellent, helped considerably by where the dust port sits relative to the cut line.
The 1-3/4 hp motor with variable speed from 11,000 to 28,000 RPM is quiet even at the top of the range, which makes it pleasant to run for a full afternoon. The soft start ramps the motor gently, and the extra long power cord gives you real reach around a large panel.
The integrated depth stop and depth scale with eight-stop increments give you repeatable preset depths, and the detachable parallel guide handles edge-aligned cuts. A pre-installed template guide mount accepts Bosch RA1128 guides, so template routing is available from the box.
A surface routing dust hood and dust collection port are included, which is unusual at this level and covers you for both surface and groove work.
Two limits to plan around
It ships with a 1/4 inch collet only, and 1/2 inch compatibility is limited. If your dado work includes wider grooves cut with a 1/2 inch shank bit, budget for a collet before you start or choose a different router.
The plunge action can be stiff or slightly jerky straight out of the box, though it smooths after break-in. The depth stop lacks a micro-adjust and feels inexpensive next to the microfine systems above, and the parallel guide is thin stamped sheet metal that is fine for light work.
Who should pass on this one
Pass if you need 1/2 inch shank capability out of the box, or if you plan to mount the router on a generic sled or third-party base. The unique base screw pattern limits what it will bolt to.
It also uses a brush rather than a brushless motor, which is normal for a corded tool at this level but worth knowing if you expect to keep it a very long time.
10. DEWALT DW621 — Best Plunge Router for Template and Jig Dado Work
DEWALT Router, Plunge Base, 10-Amp, 2 HP (DW621)
10 amp 2 HP
8000-24000 RPM
Rack and pinion micro-fine
Bronze bushings
Integral dust extraction
Pros
- Rack and pinion depth adjuster with micro-fine adjustment
- Full-wave electronic speed holds constant RPM under load
- Phosphorous bronze bushings give a smooth and accurate plunge
- One-piece motor shaft and spindle maintain perpendicularity
- Guide bushing adapter plate accepts standard bushings
Cons
- Dated design with fewer modern features
- 10 amp motor pulls less power than 12 and 15 amp competitors
- Smallest review count among the corded plunge routers here
This is the oldest design in the group and it still works. Owners describe it as a dependable, accurate workhorse whose rack-and-pinion depth adjuster and bronze bushings hold up well, and for jig-based dado work the accuracy of the bushed plunge is the point.
The guide bushing adapter plate accepts standard guide bushings for template work, which is what makes this a good choice when the groove has to repeat in the same position across a batch of identical parts. Combined with the one-piece motor shaft and spindle, you get perpendicularity that holds up over time.
The full-wave electronic variable speed motor runs 8,000 to 24,000 RPM with soft start and holds constant speed under load. Rubber-coated knobs combine the plunge lock and the on and off switch into a single control you can find without looking down.
Integral dust collection removes chips and improves bit visibility during cuts, and a spindle lock button allows single-wrench bit changes. The collet takes both 1/4 inch and 1/2 inch bits, so the same body covers a range of groove widths.
What the age of the design means
The 10 amp motor pulls less power than the 12 and 15 amp machines here. On a deep dado through thick hardwood you will be more likely to make two light passes than one heavy one, and variable speed gives you some control over how you handle that.
Owners are candid that the styling is dated and the feature set is thinner than newer models. What you do not get is a micro-fine ring, LED lighting or a through-column chip path.
Who should pass on this one
Pass if you want a modern feature set or the highest chip extraction. There are newer machines in this list that do both better.
With only 94 reviews, this carries the smallest corded review base here. It is a well-regarded design rather than a controversial one, but there is less owner data to draw reassurance from.
How to Cut a Dado with a Plunge Router
A dado is a flat-bottomed groove cut across the grain, usually in a board or panel face. That flat bottom is the whole reason it needs a plunge router: a fixed-base router can only cut a groove that runs off the edge of the workpiece, which is awkward, risks blowout on the exit side and limits you to open-ended grooves.
The plunge method is faster and safer because the bit starts and ends inside the board, entirely under your control. It also produces the stopped grooves and housings that cabinet and face-frame joinery depends on, since a straight edge or template jig guides the pass.
Here is the sequence we used for every router in this roundup.
1. Choose the bit. A straight two-flute or four-flute bit in 1/4 inch or 1/2 inch shank is the standard for dados. Two-flute bits cut faster and clear chips well in softwood and plywood. Four-flute bits hold an edge longer and give a cleaner cut in hardwood, at the cost of more heat. Match the shank to your router’s collet capacity, and check that your collet is at least as large as the shank.
2. Set the depth. Set your desired dado depth, then subtract the diameter of the bit. A 1/2 inch bit cutting a 1/4 inch deep dado needs the bit to sit 1/4 inch below the surface, so set 3/4 inch total from the board face. If you have a plunge router with a turret or preset stops, set the first shallow stop now rather than later.
3. Guide the cut. This is the step that decides whether your dado is straight. Use a straight edge clamped to the workpiece, a router table with a fence, or a template jig with a guide bushing. Clamp the guide before you unpower the router, and clamp the workpiece before anything else. An unclamped workpiece is never a workpiece you plunge into.
4. Plunge to speed at zero depth. Set the base flat on the board, bring the bit to full speed with the tip just touching or a hair above the surface, and only then release the plunge lock. Never start the motor with the bit already below the surface.
5. Take a shallow first pass. Plunge down about 1/8 inch and make your first pass along the guide. The purpose is to establish a clean reference line and open a channel for chips, not to reach final depth. Confirm the position against your measurement before you go further.
6. Step down to final depth. Release the plunge, move back to the start, and step down in increments of roughly 1/8 inch, taking a pass at each depth. Can you plunge cut with a straight router bit? Yes. A straight bit at 90 degrees is not an ideal chip-clearing geometry, so multiple shallow passes are what keep the cut accurate and the bit cool.
7. Finish and check. On the final pass, run the router along the full length once more without changing depth, then release the plunge and back the bit out before you stop the motor. Measure the depth at both ends and in the middle. If one end is deeper, a straight edge helps on a shallow pass, and a second light pass at that depth usually brings them together.
For plywood and sheet goods, take shallower passes than you would in hardwood. Plywood edges chip easily and the layers delaminate under heavy load, so a shallower cut with a lighter feed is kinder to the panel.
Buying Guide for Plunge Routers Used on Dado Work
Collet capacity. Most plunge routers in this roundup take both 1/4 inch and 1/2 inch bits, and a 1/2 inch collet is the one worth insisting on. Wider straight bits and larger core box bits need it, and it also gives you more choice when you move from dado work to flush trimming and pattern routing. The Bosch GOF13-25 here ships with a 1/4 inch collet only, so plan around that if you buy it.
Plunge depth. A dado is usually a quarter inch or less, so any plunge capacity will cover joinery. The deeper travels matter when you cut through-dados in thick timber or plunge into the edge of a board. The Makita RP0900K offers 1-3/8 inch, the WEN RT6033 reaches 2-3/8 inch, and the mid-size machines sit between them. How deep a plunge router cuts is really a question of motor power as much as travel. A shallow plunge with a weak motor stalls; a deep plunge with a strong motor does not.
Plunge smoothness and base flatness. This is the least advertised and most important factor. A smooth column with ball bearing or bronze bushings keeps the bit on a straight vertical path. A loose column that rocks at the bottom of the stroke introduces error precisely where you are cutting to a set depth. The DEWALT DW618PKB and DW621 both use machined brass or bronze bushings, and owners comment on how solid the plunge feels. Before you commit to jig work, check your own unit for bottom-out play.
Depth adjustment and turret stops. For a single groove depth, almost anything works. For stepped or multiple-width dados, the adjustment resolution is what you are paying for. The DEWALT DW618PKB sets depth in 1/64 inch increments on a micro-fine ring that adjusts vertically, keeping the switch and cord in a constant position. The Triton TRA001 uses a micro winder for continuous fine movement across the whole range. The Bosch 1617EVSPK and DeWalt DCW620B pair macro adjustment with micro-fine rings, and turrets on the WEN and Triton give you preset positions for repeated depths.
Dust and chip extraction. Plunge routing in a groove produces a surprising volume of chips. Through-the-column extraction, as on the DEWALT DW618PKB, pulls chips up and out through the motor column, and the cordless DCW620B routes chips up a vertical post and captures up to 97 percent in particleboard grooves. Port-mounted extraction is weaker but adequate with a shop vacuum on a smaller groove. The Metabo HPT and the Bosch GOF13-25 are the weakest here on chip capture, so plan extraction around them.
Power and speed control. 12 to 15 amps is the mainstream range, and constant speed under load matters more than peak horsepower. Electronic speed control from about 8,000 RPM to 24,000 RPM or higher lets you slow down for large-diameter bits and in figured hardwood, and soft start prevents a jerk on contact. If you cut a lot of hardwood, prioritise a motor that holds speed when loaded over one that merely advertises high peak horsepower.
Weight and balance. Heavier is not better for handheld dado work. The heaviest router here is 18.2 pounds and the lightest is 6.9 pounds, and that difference is the difference between finishing a cabinet and putting the tool down. Look at how the weight sits, not just the total. A tool with angled handles and a compact height is easier to control than a heavier one with straight upright grips.
Corded or cordless. Corded routers never stop and are the safer default for long dado runs through thick timber. Cordless plunge routers win when the work is away from an outlet, on stairs, or on an installed cabinet, and the DeWalt DCW620B adds an anti-rotation shutdown that protects against a snag. If you already own batteries for a platform, a cordless plunge router is a cheap second router rather than a replacement.
Fixed base or plunge only. A dual-base kit covers plunge work and edge work in one package. A plunge-only router that locks its base down, like the WEN RT6033, does the same thing with less to store. If you already own a decent fixed-base router, a plunge-only model is the tidier buy, and the beginner router guide covers that half of the pairing.
Router table use. Plunge routers mount to a router table well, but above-table depth adjustment is not universal. The Triton TRA001 is built for it, with a table height winder, above-the-table bit changes through the base and a 3-stage turret. The Bosch 1617EVSPK has a threaded three-hole base pattern that secures to most tables, and the DEWALT DW618PKB has a clear LEXAN sub-base that accepts standard guide bushings. Check your table’s plate pattern before you buy, especially for the Bosch GOF13-25, whose base screw pattern is unique.
Brand and warranty. On service and parts, the established names in this list have the deepest networks, and the Metabo HPT carries a lifetime warranty on the tool body while Bosch corded tools carry a one-year limited warranty. If you want the lowest-risk purchase, weight the size of the existing owner community as much as the warranty length.
Frequently Asked Questions
Can I cut a dado with a router?
Yes. A plunge router is the better tool for a dado because it can start the cut in the middle of a clamped board and stop it at an exact depth. Set the base flat on the surface, bring the bit to full speed at zero plunge depth, take a shallow first pass, then step down in small increments to your finished depth.
What router bit is best for making dados?
A straight bit is the standard choice. Two-flute straight bits cut faster and clear chips well in softwood and plywood, while four-flute straight bits hold an edge longer and give a cleaner cut in hardwood. Match the shank to your collet capacity, and step down in shallow passes rather than one deep cut.
Can you plunge cut with a straight router bit?
Yes, but a straight bit at 90 degrees is not ideal chip-clearing geometry. Take multiple shallow passes of about 1/8 inch each, letting the bit reach full speed at every depth before you advance. Slower passes and steady feed keep the cut accurate and the bit cool.
How do you keep a router dado straight?
Guide the cut with a straight edge clamped to the workpiece, a router table fence, or a template jig with a guide bushing. Clamp both the guide and the workpiece before you unpower the router, and never plunge a bit into an unclamped board.
How deep will a plunge router cut?
Plunge capacity varies widely, from 1-3/8 inch on a compact router to more than 2-3/8 inch on larger machines. Most dados are a quarter inch or less deep, so travel is rarely the limiting factor. Motor power matters more, because a weak motor stalls under load before it reaches its rated plunge depth.
Which is better, a fixed or plunge router, for dados?
A plunge router, for anything that starts in the middle of a board. A fixed-base router can only cut a groove that runs off the edge, which risks blowout on the exit side and makes stopped grooves and housings awkward. A dual-base kit gives you both, and the plunge base locks down to handle the edge work afterward.
Final Verdict
The Bosch 1617EVSPK is the best plunge router for dados in 2026. It pairs a microfine depth ring with a one-piece armature shaft that keeps vibration low, ships with both a plunge and a fixed base, and carries the strongest owner rating and review record of anything we tested. If you can handle 18.2 pounds, it is the one router that covers almost every dado situation you will meet.
Buy the SKIL RT1322-00 if you want a capable machine without the top-of-range outlay, the DEWALT DW618PKB if you cut stepped or multiple-width grooves and want 1/64 inch depth control with real chip extraction, and the WEN RT6033 if budget is the deciding factor. If the work is away from an outlet, the DEWALT DCW620B is the cordless answer, and the Metabo HPT M3612DAQ4 is lighter still at 6.9 pounds.
Whichever one you choose, the router only makes half of a good dado. Clamp the workpiece, clamp the guide, take shallow passes, and the joint will come out square every time. Check the current details for each pick before you order, then make the test cut in a scrap board.
