The Craftsman CMCW221B is a lightweight, cordless detail sander designed for precision work in tight spaces, featuring a variable speed range of 9,000 to 12,000 OPM and a versatile dust collection system. It operates on the Craftsman V20 battery platform and includes a dust-sealed switch and D-handle for ergonomic control during vertical sanding tasks. While ideal for DIYers and professionals seeking portability and clean operation, the bare tool format and non-standard sandpaper sizes are notable trade-offs.

The BLACK+DECKER BDCMS20B is a cordless 20V MAX* bare-tool mouse detail sander designed for sanding in tight corners and small spaces. It features a compact ergonomic design with an interchangeable detail finger attachment, variable speed up to 12,000 RPM, and a hook-and-loop sandpaper system for easy changes. While it offers excellent portability and control, the requirement to buy batteries separately and the lower speed compared to corded models are significant considerations.
