An innovative abrasive 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. Can be easily dressed using an old file. 6″ long and 1/2″ Square; 120 grit. Made in Japan.
