Bosch X-Lock Flap Discs 4-1/2" - 40 Grit

Bosch's X-Lock Abrasive Sanding 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 an X-LOCK wheel on an X-LOCK grinder. The wheel mounts properly without the need for a spanner wrench or flange nuts. The wheel is released from the grinder with the pull of a lever. The pads work with Bosch abrasive sanding fiber discs made with high-quality aluminum oxide grit for exceptional speed and durability in tough environments.
