The 3" Carbon Steel Crimped Wire Cup Brush offers continuous brushing action for removing rust, scale, and weld splatter. The durable carbon steel wire construction is ideal for edges, paint-scale and light rust removal on flat or irregular surfaces. 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).
