The Craftsman V20 Router (CMCW400B) is a cordless compact fixed-base router on Craftsman’s V20 battery platform—not a router lift, not a CNC, and not a corded mid-size plunge beast. Sold as a bare tool, it expects a battery and charger you may already own. This review covers brushless power feel, speed range, depth adjustment, and where cordless compact routing actually wins.
Cordless compact routers earn their keep when the cord is the enemy: hinge mortises in a hung door, laminate trim on a countertop already installed, round-overs on a deck rail, or punch-list edges in a finished room. The Craftsman V20 CMCW400B sits in that category—a fixed-base compact router with a brushless motor, a depth adjustment knob, a variable-speed dial cited around 16,000 to 30,000 RPM, and an LED to light the cut. It is a real router, just not a two-base corded kit or a CNC gantry.
Brushless marketing is everywhere, but on a compact cordless tool it usually means better efficiency and longer brush life than older brushed designs. You still have to match bit size and depth to what a compact motor can honestly do. Thin round-overs, chamfers, flush trims with a small bit, and light dados in softer stock are the happy path. Deep hardwood plunges with a fat straight bit are how you invent disappointment—and heat.
Craftsman includes an edge guide and dust port adapter, which is more than some bare tools bother with. The edge guide turns straight reference cuts into something repeatable against a board edge; the dust adapter helps when you can park a hose nearby. LEDs are not a gimmick inside a dark cabinet. Depth adjustment via knob is the daily interface—sneak up on final depth, lock your habits, and test on scrap every time you change bits.
Because this listing is bare tool only, your total kit depends on whether V20 batteries already live in your shop. If they do, the CMCW400B is an easy add. If they do not, budget a battery and charger as part of the real purchase—even though we are not quoting prices here. Platform lock-in is the quiet decision underneath every cordless compact router review.
Who should buy it? Remodelers, homeowners, and woodworkers already on Craftsman V20 who want cordless edge work without dragging a cord across finished floors. Who should skip it? Anyone needing a mid-size plunge for deep template work, a table-mounted workhorse, or a CNC for carved parts. Also skip if you expected a JessEm-style lift—that is a completely different product family.
Compared with corded palm routers, you trade unlimited runtime for mobility and cleaner jobsite manners. Compared with premium cordless routers from other brands, decide based on the batteries you already own and the bit sizes you actually run. Soft-start manners, trigger or switch feel, and base stability matter as much as amp slogans once the bit touches wood.
Verdict: the Craftsman V20 Router is a credible cordless compact fixed-base router for people living in the V20 ecosystem. Buy it for trim, hinges, and mobile edge work. Do not buy it as a lift, a jig, or a desktop CNC—and do not forget the bare-tool battery reality before you click purchase.
Who it's for
V20 owners and cordless-leaning DIYers who need a compact fixed-base router for trim, hinge work, and light profiling without a cord.
Who should skip it
Skip if you need a full-size plunge router, a table lift, or you have no V20 batteries and refuse to join that platform. Match the motor class to the cut.
Battery & bare-tool reality
CMCW400B ships as a bare tool. Plan battery capacity around your longest trim sessions, and keep a second pack if you route continuously on site.
Best everyday tasks
Round-overs, chamfers, flush trimming with appropriate bits, hinge mortising with guides, and light edge work where dragging a cord is the real hazard.
- Cordless freedom for trim, hinges, and punch-list work
- Brushless motor targets runtime and performance
- Useful speed range for small bits and materials
- Edge guide and dust adapter in the box
