Cordless routers have grown from light trim tools into full-size woodworking machines. Current models spin 1/2-inch bits, plunge into stock, and run long enough on a pair of batteries to edge a whole cabinet run. That capability changes how you shop, because a router purchase is really two decisions at once. The first is the tool itself: power, base style, and bit capacity. The second is the battery platform, since the same packs will power drills, saws, and sanders for years.
Timing shapes the value of both decisions. Retail prices on cordless routers swing sharply during the holiday season, and knowing how tool prices shift after Black Friday tells you whether to buy at the first sale or wait for the January dip that follows.
Full-Size Router or Trim Router: Match the Tool to the Work
The first question is not which brand, but which class. Trim routers are small, light, and built for edge profiling, laminate trimming, and light hinge work. Full-size routers carry bigger motors, accept 1/2-inch shank bits, and handle joinery, raised panels, and template work that a trim router cannot manage.
The size difference shows up in the numbers. A typical trim router weighs 3 to 4 pounds and spins at 25,000 to 30,000 RPM with a single speed. A full-size router runs 8,000 to 25,000 RPM with variable speed, weighs 7 to 12 pounds, and delivers 1.5 to 3.25 horsepower.
When a trim router is enough
A trim router earns its place when the work stays small:
- Rounding over edges on boards up to about 3/4 inch thick
- Trimming laminate edges flush after glue-up
- Cutting hinge mortises and small dados
- Cleaning up flush-trim joints with a bearing bit
Where a full-size router earns its space
Full-size routers pay for themselves on heavier work:
- Raised panel door construction with large profile bits
- Dovetail and box joints cut with a jig
- Template routing of sign blanks and shelves
- Freehand work where 1/2-inch shank bits reduce chatter
The same seasonal calendar that drives Black Friday miter saw deals also sets the cadence for router discounts, so the class of tool you need can change what you wait for.
Power, Speed, and Collet Size: Reading the Spec Sheet
Router specs look simple until you compare two models side by side. Horsepower tells you sustained cutting ability, but only when the motor holds speed under load. Brushless motors hold speed better than brushed designs, run cooler, and draw less from the battery, which is why nearly every new cordless router uses them.
Variable speed matters more on a router than on almost any other tool, because large bits have higher rim speeds. Running a 2-inch panel bit at full 25,000 RPM risks burning the wood and stressing the bit. The speed dial lets you drop to 16,000 to 18,000 RPM for big cutters.
Horsepower versus torque
Rated horsepower on cordless routers ranges from about 1.5 to 2.5 HP equivalent, but the rating means less than how the motor behaves at half battery. Hands-on testing of the Metabo 36V cordless variable speed plunge router shows how stall resistance and run time compare with corded performance, and the pattern repeats across brands: the first minute of a cut feels strong, then battery voltage sags and speed control decides whether the cut stays clean.
Soft start and electronic speed control
Soft start ramps the motor up instead of kicking, which keeps the router from jerking sideways at startup and reduces bit runout on plunge cuts. Electronic speed control compensates as voltage drops, holding the set RPM longer through the charge.
Collet size changes bit selection
Collets are the metal sleeves that grip bit shanks. A 1/4-inch collet fits trim bits and most edge profiles. A 1/2-inch collet takes the heavy shanks used on panel and joinery bits, and the thicker shank flexes less, so cuts stay cleaner at depth. A full-size router with both collets covers the widest range of bits, which is why dual-collet models outsell single-size versions.
Battery Platforms: Voltage, Amp Hours, and the MultiVolt Question
The battery platform decision usually outlives the router. Buy into an 18V line and the packs feed drills, impacts, and saws. Higher-voltage lines such as 36V or 40V trade weight for power, and several brands now sell dual-rated packs that work across two voltages.
Dual ratings confuse buyers until the math clicks. A 4 amp hour pack rated at 36V stores 144 watt hours. Run those same cells in an 18V tool and the effective rating doubles to 8 amp hours, because watt hours, the real measure of stored energy, stays the same. The label changes, the energy does not.
Watt hours versus amp hours
Amp hours describe current over time, watt hours describe total energy. Two packs with the same amp hour rating can store very different energy if the voltages differ, so compare watt hours when choosing between platforms.
System compatibility
Packs are not interchangeable across brands, and even within one brand, older tools may not accept newer high-capacity batteries. Before you commit, check which tools share the platform and how long the line has been supported.
Retail pressure adds another layer. Before choosing a platform, learn how to compare retailers, brands, and tool types so a tempting discount does not lock you into a system with thin future options.
Questions to answer before buying into a platform:
- How many tools in the line share this battery?
- Does the brand publish a battery compatibility chart?
- What do replacement packs cost relative to the tool price?
- Are there dual-voltage packs that bridge old and new lines?
Tool-Only, Kit, or Starter Bundle: Doing the Deal Math
Cordless routers sell in three shapes. Tool-only drops the battery and charger and assumes you already own the platform. A kit adds one battery, a charger, and usually a bag. A starter bundle pairs the tool with a larger battery and charger, sometimes with the battery value buried in a separate promo.
The shapes interact with coupons in surprising ways. A tool-only price can fall below half the kit price, while a promotional starter bundle can include a higher-capacity battery than the standard kit. Do the math on actual contents, not the headline discount.
| Option | What you get | Typical sale price | Best for |
|---|---|---|---|
| Tool only | Router, collets, guides, bag | $130 to $160 | Buyers already in the platform |
| Kit | Router, 2.5 to 5 Ah battery, charger, bag | $350 to $450 | New owners who need everything |
| Starter bundle | Router, 4 to 8 Ah battery, charger | $130 to $160 with promo | Platform entry on a budget |
Why tool-only deals win for some buyers
Tool-only pricing makes sense when you already own batteries and chargers. The router becomes an add-on to an existing platform, and the savings can fund a second battery later.
Counting the battery into the price
When a promo bundles a free battery, value the battery at its retail price and subtract it from the total. A $139 router with a battery that normally costs $120 is effectively a $19 router, which beats most tool-only prices.
Bundles also shift when brands consolidate. The 2024 pairing of Metabo HPT and Metabo under one roof changed how their cordless lines share batteries and chargers, and buyers who track the merger’s meaning for tool buyers have found better bundle pricing as the two catalogs align.
Accessories in the Box: Collets, Guides, and Dust Collection
The contents of the box often decide the real value of a deal. Most full-size routers ship with 1/4-inch and 1/2-inch collets, a collet wrench, a template guide set, a straight or edge guide, and dust collection attachments. Adding those pieces separately can cost as much as a budget trim router.
Template guides turn the router into a pattern-following machine for hinge mortises and shelf pin holes. The straight guide rides a fence for groove cuts parallel to an edge. Dust collection attachments matter more than they look, because a router throws chips directly at your face and a shop vac port keeps the cut line visible.
Template guides and when you need them
Template guides are metal rings that screw to the sub-base. A bushing rides against a template while the bit cuts inside, which lets you reproduce the same mortise or hinge pocket on every piece.
Dust collection setup
Look for a shroud that fits over the bit with a 1-1/4 or 2-1/2 inch port. A clean cut line is also a safer one, since you can see the bit and the stock.
Corded routers still lead on sustained power, and tests evaluating router power and performance show why many shops keep one plugged in even after switching their everyday tools to cordless.
Buying Checklist: What to Verify Before You Pay
A deal is only a deal if the configuration matches your needs. Run through the list before checkout:
- Confirm both collet sizes are included or that the model accepts the bits you own.
- Check whether the price includes a battery and charger, and what capacity that battery carries.
- Verify coupon stacking, since some discounts exclude already-marked-down items.
- Note the expiration date of each promo, because buy more, save more tiers reset at thresholds.
- Compare the total with shipping and tax against the kit price at other retailers.
- Confirm the battery fits your existing tools and vice versa.
- Read the return policy before relying on a holiday price match.
The same checklist applies beyond routers. A contractor review of the Metabo HPT 18 gauge cordless brad nailer shows how buyers verify duty cycles, magazine capacity, and consumable costs before committing, and the habit of checking configuration before price keeps every tool purchase honest.
