Overview
Spinning up to 30,000 RPM on an 18 volt battery, Craftsman's CMCW400B is a compact cordless trim router weighing 4.1 pounds, drawing 2 amps for edge and trim work rather than heavy stock removal.
Compact trim routers trade table-mounted power for portability, and the CMCW400B's 30,000 RPM top speed keeps it in that category, suited to edge profiles, laminate trimming and light detail work. The CMCW naming's B suffix commonly signals a bare tool sold without battery or charger, so check the listing carefully if you need those included.
- 18 volt cordless power source
- Top speed of 30,000 RPM
- 2 amp motor draw
- Weighs 4.1 pounds
Who it's for
Woodworkers who already own Craftsman's 18 volt battery platform and want a portable trim router for edge work, roundovers or laminate trimming are the fit. It's not the tool for heavy dado or full depth routing, where a corded, higher powered router does more per pass.
Strengths and trade-offs
Drawn from this product's published specifications.
- Reaches 30,000 RPM for clean edge cuts
- Cordless and light at 4.1 pounds
- Runs on Craftsman's 18 volt battery system
- 2 amp draw limits it to lighter cuts
- B suffix suggests bare tool, no battery included
Performance notes
Speed is the main lever on a trim router, and 30,000 RPM keeps the bit moving fast enough for clean edges in wood and laminate despite the modest 2 amp draw. Running cordless at 4.1 pounds keeps the tool maneuverable for one-handed use, though battery powered routers generally sustain less power than a corded model on repeated heavy cuts.
