Bosch's X-lock backing pads feature the X-lock mount that offers a wheel change that's up to five times faster than conventional interfaces. There's an audible snap when mounting the X-lock backing pad on an X-lock grinder. The wheel mounts properly with the included X-lock clip. The wheel is released from the grinder with the pull of a lever. The pads work with Bosch abrasive fiber discs made with high-quality zirconia grit for exceptional metal removal and finishing. Bosch X-lock backing pads are not backward compatible with standard 7/8 in arbor mounts.
