The 3 In. Brass-Coated Carbon Steel Crimped Wire Cup Brush offers continuous brushing action for removing rust, scale, and weld splatter. It is ideal for edges, paint-scale and light rust removal on flat or irregular surfaces. The brass-coated carbon steel wire is resistant to rust for increased durability over standard carbon steel wire. The X-LOCK quick change system provides up to 5x faster cup brush changes vs. a standard angle grinder mount. Simply pull the release lever on the X-LOCK Angle Grinder and change the wire cup brush no tools needed. For use with Makita X-LOCK Angle Grinder models XAG25, XAG26 and GA4570 (sold separately).
