Overview
The CMCW221B is Craftsman's cordless sander, built on the brand's 20V platform. It spins at up to 12,000 RPM and weighs about 1.18 kg (2.6 lb) bare, making it a compact option for one-handed sanding work around the shop or job site.
Cordless sanders trade outlet dependence for battery run time, and the listing here does not state whether a battery or charger is included, so confirm bare tool versus kit before ordering. At 12,000 RPM it sits in a typical range for orbital and detail sanders rather than the aggressive end. Pad size and sanding pattern, whether random orbit, sheet or detail, are not specified.
- 20V cordless power source
- 12,000 RPM no load speed
- 1.18 kg (about 2.6 lb) weight
- Part of Craftsman's V20 tool lineup
Who it's for
Suits DIYers and tradespeople already invested in Craftsman's 20V battery system who want a lightweight sander for touch up and finish work. Less suited to anyone needing heavy stock removal or a corded tool for continuous all day use.
Strengths and trade-offs
Drawn from this product's published specifications.
- Compact 1.18 kg body for one-handed use
- Runs on Craftsman's shared 20V battery platform
- 12,000 RPM suits finish sanding
- Pad size and sanding pattern not specified
- Battery and charger inclusion unclear from listing
- No stated dust collection details
Performance notes
Speed alone does not fully describe cut rate, since that depends on pad size, sanding pattern and grit, none of which are listed here. The 1.18 kg weight suggests a tool built for one-handed control rather than sustained heavy pressure, which fits detail and finish sanding more than aggressive material removal.
