BSD Corner Tool 2-Pack


The BSD Corner Tool is an extension to the Easy Edge product line. With it, you can easily blend corners to match the edges and floor. Works great on stairs, door jambs, and countertops.

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.

When ordering, please note that these come in a 2-pack. To order 4 tools total, select a quantity of 2. The BSD Corner Tool is also available in a 5-Pack Starter Set.
