Ryobi Corner Cat
Score: 78/100Rankings

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 Ryobi 18V Corner Cat Finish Sander is a cordless tool with a compact triangular base designed for accessing corners and tight spaces during light finishing tasks. Its modest power and battery dependency make it unsuitable for heavy stock removal or extended professional use. It is ideal for DIYers and hobbyists with Ryobi ONE+ batteries needing a lightweight sander for finish sanding corners and edges.
