Cordless routers have crossed from convenience to everyday tool in most woodworking shops. The tipping point was the pairing of brushless motors with high-capacity batteries, which gave cordless models enough sustained power for edge profiles, hinge mortises, and trimming work. Deal pricing helped push the category forward, too: spring promotions have bundled a battery and charger with the bare tool at prices close to what the tool alone cost a year earlier. Before spending, it helps to understand how router power and performance translate into cutting ability, because the numbers on the box do not always predict how the tool behaves in walnut, plywood, or edge banding.
Fixed Base versus Plunge Routers
The first decision is the base style. A fixed base holds the motor at one depth, which makes it fast to set up and stable for edge work. A plunge base lets you lower the bit into the workpiece under power, which is the right choice for mortises, dados, and interior cuts. New buyers usually start by comparing fixed base versus plunge router features before choosing which to buy first.
When each base earns its place
The table below summarizes the practical differences. The short version: if you trim edges and profile boards, a fixed base covers the work; if you cut hinge mortises and inlays, a plunge base does the job.
| Feature | Fixed base | Plunge base |
|---|---|---|
| Depth control | Set once, locked in place | Adjustable while cutting |
| Best for | Edge profiles, trimming, roundovers | Mortises, dados, inlay work |
| Setup time | Fast | Slower, more adjustment points |
| Learning curve | Gentle | Steeper |
| Typical use | Trim work, shelving edges | Door hinges, sign work |
| Entry price | Lower | Higher |
Many manufacturers sell kits with both bases, which is often cheaper than buying a second router. The motor swaps between bases in seconds, so one tool covers edge work and mortising. Two-base kits add a little cost and a lot of capability, and they are the most common recommendation for a first router.
Cordless versus Corded Power
Corded routers still hold the top of the power range, with full-size motors rated from 1.5 to 3.25 horsepower. Cordless routers mostly sit in the trim-router class, and early cordless models were measured against compact 12-volt edge routers rather than full-size machines. The gap has narrowed as 18V brushless designs matured, but the class distinction still organizes the buying decision.
Horsepower, watts, and real cutting capacity
What the ratings actually tell you
A corded trim router rated at 1 to 1.25 horsepower handles most edge work, and a modern 18V brushless cordless router matches that range for intermittent cuts. Watt ratings matter more than peak marketing numbers, because sustained watts determine whether the motor holds speed under load. A router that bogs down on a 1/2-inch roundover in oak tells you more than the label ever will. Test the tool on the material you actually cut: softwood edges are easy, hardwood profiles and deep dados are the real exam.
Collet size also separates the classes. Trim routers and most cordless models use 1/4-inch collets, which limit the bit selection; full-size routers accept 1/2-inch shanks that resist deflection in deep cuts. If your work stays at 1/4-inch shank territory, a cordless trim router covers it. If you regularly run raised-panel bits or template work with long cutters, the stiffer 1/2-inch shank is worth the switch to a larger machine.
For hinge mortises and shallow dados, cordless is enough for most shops. For table-mounted production work and heavy stock removal, a corded router or a larger motor still wins. Many shops run both, keeping a cordless router near the bench for setup and trim and a corded router for long runs.
Battery Life and Runtime Planning
Battery life is the practical limit on cordless routing. A 6.3 amp-hour pack on a brushless router runs substantially longer than a 2.0 amp-hour pack, and manufacturer runtime claims assume specific cut depths and materials. Cordless router technology keeps improving on motor efficiency and cell capacity, which is why a modern 18V router outperforms an early-generation model with the same voltage.
Matching battery capacity to the job
Plan around the factors that drain a pack fastest:
- Cut depth and bit size: deeper cuts and wider bits draw more current
- Material density: oak and maple pull more power than pine and poplar
- Speed setting: full RPM drains the pack fastest, and most edge work does not need it
- Battery age: cells lose capacity after a few hundred charge cycles
To estimate runtime on your own work, run a short test before trusting the label:
- Time a one-minute pass at your normal depth and speed on the material you use most.
- Note the battery indicator drop after that pass and project the total runtime.
- Repeat at a deeper cut setting to see the worst case.
- Compare the result with a fresh pack, because older cells sag sooner.
- Adjust the plan so one pack charges while the other is in the tool.
A practical rule is to keep a second battery charged and swap when the tool slows, because routers draw more current than drills and the voltage sag shows up as bogging before the pack is empty. Charging one pack while you cut with the other keeps the workflow continuous, and a fast charger turns a lunch break into a full battery.
One Battery Platform, Many Tools
The strongest argument for a cordless router is the battery platform behind it. The same 18V packs that run a router also power drills, drivers, and saws, and manufacturers keep extending their platforms with compact brushless fastening tools that share chargers and cells. Every battery purchase then serves multiple tools, and the marginal cost of adding a router drops.
How a shared platform changes the buying decision
If you already own batteries, a tool-only router is a cheap addition to the kit. If you are starting fresh, the kit price with battery and charger is the real entry cost, and it often beats buying the pieces separately. Check that the packs you own are compatible and that the router does not require a high-output pack to reach full speed; some brushless models limit power on smaller batteries, and that limitation shows up as bogging on deep cuts.
The platform math rewards consistency. Two batteries and a fast charger support a router, a drill, and a driver on the same charge rotation, and the spare pack you already own for one tool becomes runtime for the next. Before committing to a platform, count the tools you actually need on it; a platform with a dozen tools justifies the investment in packs, while a platform you will use for one tool does not.
Router Tables and Stationary Use
A router table turns the tool into a stationary shaper, and the motor choice changes when the router lives in a table. Table work favors a motor with a long body, a fixed speed, and easy above-table adjustment, which is why selecting a router motor for a router table follows different rules than picking a handheld model.
When a cordless router belongs in a table
Cordless routers work in a table for light production and quick setups, especially on site where power outlets are scarce. Corded motors remain the standard for heavy table work, because continuous duty drains packs quickly and stationary use does not benefit from portability. A common compromise is a cordless router for setup cuts and short runs plus a corded motor for long production passes, with the cordless unit staying available for handheld work between table sessions.
Building a Router Setup on a Budget
The hidden cost of routing is accessories. Bits, guides, and finishing tools add up faster than the router itself, and a starter set of common profiles beats a huge assortment of rarely used shapes. The same shopping discipline applies to choosing router bits and finish sanders: buy the profiles you use weekly, then expand.
Stretch the budget without cutting corners
Starter kits change the math. In one spring promotion, a brushless 18V router kit with a battery and charger sold for $189, while the bare tool ranged from $149 to $184 at other retailers and the full kit with a hard case ran about $399. When the kit price is close to the bare-tool price, the battery is effectively free. Add a 1/4-inch straight bit, a roundover bit, and a flush-trim bit, and a basic setup is complete. Deal timing matters, too: flash sales and holiday events routinely drop router prices, and comparing tool-only versus kit pricing at the same store reveals which bundle saves real money.
Bit quality separates frustration from clean cuts. Carbide-tipped bits hold an edge longer than high-speed steel on abrasive materials such as plywood and MDF, and a 1/4-inch shank is the practical ceiling for most cordless collets. Buy a few good profiles instead of a big box of cheap ones, and replace bits when the cut starts to burn rather than when they look dull.
