Cordless routers arrived later than cordless drills and saws because routing demands sustained power, but modern battery systems have closed the gap. A mid-size cordless router now claims to replace a corded model outright, with 2.25 peak horsepower, variable speed control, and runtime measured in hundreds of feet of actual cutting. The shift matters for anyone who works wood away from an outlet, from carpenters on jobsites to homeowners in detached garages. Portable power supplies for cordless equipment have extended the same freedom to heavier tools, and routers are the latest tool type to make the jump. Choosing one comes down to power, bases, batteries, and bits, and each decision changes how the tool performs on real work.
How Router Power Is Measured
Router power is quoted in peak horsepower, a marketing number that describes the motor’s maximum output under load rather than continuous running power. A mid-size cordless router with 2.25 peak horsepower sits in the same class as many corded mid-size models, which is why manufacturers describe them as complete replacements rather than compromises. Bench tests that focus on evaluating router power and performance show how much of the rated number actually reaches the bit, and the same methods apply to cordless models.
Speed range matters as much as raw power. A variable-speed dial from 12,000 to 25,000 RPM covers the full spread of router work: large bits and hardwoods run best near the low end, while small bits and softwoods tolerate the high end. Fixed-speed routers force a compromise that variable-speed models avoid.
Reading the Spec Sheet
Manufacturer spec sheets pack useful numbers, but only some of them translate to real performance.
| Specification | What it tells you | Typical mid-size value |
|---|---|---|
| Collet sizes | Which bits the tool accepts | 1/4 inch and 1/2 inch |
| Speed range | Versatility across materials | 12,000 to 25,000 RPM |
| Tool weight | Fatigue over a workday | 8 to 9 pounds |
| Base travel | Depth range for plunge work | Over 2 inches |
| Runtime | Cutting time per charge | Up to 225 linear feet |
Why Speed Range Matters
Large-diameter bits generate more heat and vibration at high speeds, which is why edge-forming bits and raised-panel bits run near 12,000 to 16,000 RPM. Small bits need the speed to cut cleanly and run at 20,000 RPM and up. A router with a narrow speed range forces you to run bits outside their safe window; a wide range keeps every bit in its comfort zone.
Fixed Base vs. Plunge Base
Routers split into two base designs. A fixed base holds the bit at a set depth, which suits edge work, trimming, and pattern routing where the depth does not change mid-cut. A plunge base lets the bit drop into the work under spring pressure, which suits dados, grooves, mortises, and any cut that starts in the middle of a board.
Most cordless routers ship as a motor plus one base, with the other base sold separately or in a kit. The tool itself carries the depth adjustment, and the best designs offer both macro and micro adjust knobs: a coarse knob for big changes and a fine knob for hair-thin tweaks. Over two inches of travel gives the plunge base room for deep cuts without resetting.
Dust Management on Cordless Routers
Routing produces a fine dust cloud, and a dust collection shroud that fits the base makes the difference between a clean shop and a coated one. The best setups connect the shroud directly to a vacuum hose; a cordless wet-dry vacuum keeps the dust stream mobile on jobsites where an outlet is already spoken for. Without collection, dust hides layout lines, settles into bearings, and lands in your lungs.
An edge guide rides along the workpiece for straight cuts, and a template guide follows a pattern for repeatable shapes. Both attach to the base and expand what the router can do without any change to the motor.
Cordless vs. Corded: Which Tools Have Made the Jump
Drills and drivers went cordless first because their power draw is modest and intermittent. Circular saws, reciprocating saws, and angle grinders followed as battery packs grew. Routers came last because they draw high power continuously, and early cordless routers ran through batteries faster than users could work.
The breakthrough was the high-output battery pack, which delivers more current without overheating. With that in place, mid-size routers reached corded-class power, and the cordless trade-off flipped: the convenience of no cord now comes with only a modest weight penalty.
The Platform Argument
Buying a cordless router means buying into a battery platform, and the platform matters more than the router itself. The same pack that runs the router powers drills, impact drivers, lights, and radios, so the platform choice locks in the rest of your cordless kit. The comparison applies across tool categories; cordless chainsaws compared across brands show how much runtime and power vary even between tools with identical voltage ratings.
Batteries, Cells, and Runtime
Runtime comes from the battery pack, not the tool. Pack capacity is quoted in amp-hours, and higher-capacity packs such as 6Ah and 8Ah units roughly double the runtime of 3Ah packs on the same tool. Cell type matters too: newer high-output cells sustain higher current draw without sagging, which keeps the router at full speed through a long cut.
Manufacturers quote runtime in linear feet of routing, which makes the number concrete. A rating of up to 225 linear feet per charge, measured with a 5/8-inch roundover bit in pine, translates to a surprising amount of finished edge before the pack needs a charger.
Understanding how battery cells and performance tiers differ helps with the purchase decision, because the difference between a standard pack and a high-output pack shows up in cut speed and runtime more than in the voltage printed on the side.
Estimating Real-World Runtime
- Bit diameter: larger bits remove more material per revolution
- Wood species: hardwoods load the motor harder than softwoods
- Cut depth and feed rate: deeper, faster cuts draw more current
- Battery age and temperature: cold packs and old cells deliver less
Fast chargers and spare packs solve the runtime problem more cheaply than a second router. A 6Ah pack on the charger while a second pack works keeps the tool running through a full day, and the charger’s speed decides how long the pause lasts.
Collets, Bits, and Matching the Tool to the Task
The collet is the tapered sleeve that grips the bit shank, and router bits come in two standard shank sizes: 1/4 inch and 1/2 inch. Trim routers accept only 1/4-inch bits; mid-size and full-size routers accept both, which opens the full catalog of bits, including the large profiles that exist only in 1/2-inch shank versions.
Bit shank size matters beyond compatibility. A 1/2-inch shank is stiffer than a 1/4-inch shank, so it deflects less under load and produces smoother cuts on heavy profiles. Users who mostly run small bits can live with a 1/4-inch collet alone; users who work raised panels, large roundovers, or deep joinery want the 1/2-inch option.
Trim Router, Mid-Size, or Full-Size
| Router class | Collet | Power class | Typical work |
|---|---|---|---|
| Trim router | 1/4 inch | Low | Edges, laminate, light trimming |
| Mid-size router | 1/4 and 1/2 inch | Medium | Edges, dados, joinery, sign work |
| Full-size router | 1/2 inch | High | Table work, raised panels, heavy profiles |
A trim router handles the small jobs that come up constantly, but its narrow base and low power limit it on deep cuts and large bits. The mid-size class is the sweet spot for most woodworkers because it accepts both shank sizes and stays light enough for hand-held use. Full-size routers spend most of their time in a table, where their weight and power are assets.
Building a Cordless Tool System
A cordless router makes the most sense inside a battery system you already own. If the platform covers the other tools you use, the router adds capability at the cost of a bare tool plus whatever base you need. If the router is your first cordless tool, the platform decision deserves thought, because every later purchase locks into the same batteries and chargers. Tools such as cordless circular saws and reciprocating saws share the packs, so the ecosystem grows in value with each addition.
Buying the Router, Then the Kit
- Inventory the cordless tools and batteries you already own
- Compare the platform’s battery sizes and charger speeds
- Decide between a bare tool and a kit with bases, collets, and bits
- Verify the collets cover the bits you plan to run
Before committing to a platform, check the direction of the lineup and how the batteries and chargers have improved; recent cordless tool lineups show how much the ecosystem can change in a few years. A router that fits a platform with a future beats a slightly better router attached to a dead end. Choose the batteries first, then the router that runs on them.
