AG0003 – GRX Spru Grinding Wheel 4 ”x1/2” x1/2”

Material for fast grinding and superb surface finishing! GRX consists of aluminum oxide dispersed in a unique elastic bond. Cuts a bit slower than silicon carbide yet imparts a very smooth surface finish – each grit yields a much higher finish than expected. Grinds platinum, gold, silver, steel and aluminum without clogging. Prevents metal surfaces from becoming scorched during processing. Very long-lasting.
