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).
