Ryobi Corner Cat
Score: 78/100Rankings
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.
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.
