This 5 pack of corner tools gives you the ability to polish hard to reach concrete areas like corners, door jambs, stairs, and more. It fits most multi-tools and is designed for wet use.

Thanks to Blue Star Diamond Technology™, the BSD Corner Tool has a stronger ceramic-bonded matrix that holds the diamond particles together. When compared to a traditional resin-bonded matrix, this tool will last longer and get corner work done faster.
