Performance Diamond Products introduces Xlerator MBA Aggressor Grinding Wheels. Made with the company's Diamond Adherence Technology, the diamond retention is increased and a longer life is achieved over vacuum brazing or electroplating. With no matrix to wear down, users can work up to 10 times faster. The diamond surface wraps around the wheel allowing close access to walls. Can also be used for grinding joints and tuck pointing. Use wet or dry, 5/8”-11 thread.
