The Tension Drill Brush is a boar hair brush head that attaches to a standard drill, for cleaning chalk and shoe rubber off Tension Board holds in a fraction of the time a hand brush takes. It works on any wooden or resin holds, so it earns its place in any home board or training wall maintenance kit.

The medium-density natural bristles are firm enough to break down caked-on grime and oils without chewing up the hold surface. Use it dry to knock off loose chalk, or wet with isopropyl alcohol for a deeper clean of grip surfaces. It's designed for a standard drill only; skip the impact driver, which can hit holds too hard and cause damage, and keep a hand brush for the tight spots behind crimps.
