Type: Drill / Manual Wheel & Rim Cleaning Brush. What's Included: 1 x Drill Wheel Cleaning Brush (1/4 in hex shank) with silicone protective collar, in the color you select at checkout. Instead of crouching at each one scrubbing spokes by hand until your fingers ache, you clip this into your drill, dip it in soapy water, and let it spin the brake dust out of every gap in seconds.
