Nylon Bristled Scrub Brush that fits any Cordless Drill. Great for heavy duty cleaning. These Drillbrush power scrubbers are our stiffest brushes for use on the most difficult to clean surfaces. This kit includes a mini size black ultra stiff original Drillbrush. This brush is great for getting into tight corners and crevices that larger brushes may clean less effectively. The smaller diameter of the round 2 inch diameter scrub brush allows access for greater control of the brush while using it to strip loose paint, clean bricks, or other harsh scrubbing applications. The increased bristle length of this brush allows the user to clean more narrow crevices or openings then the normal bristle length brushes. Cordless Drill Not Included.
