These packages of Silicon Carbide Ungraded 60/90 Coarse Grind Grit (available in varying amounts) are designed for use in tumblers, flat laps, sphere machines, or other rock tumblers where coarse and fine grinding grits are necessary.

Diamond Pacific outlines the basic grit sequence as follows, but it can be modified depending upon material: The standard sequence for a rotary tumbler is 60/90, 220 and 600 silicon carbide, followed by a polish. For best results, use an aluminum oxide pre-polish 800 grit before the final polish. Use this same silicon carbide sequence including the aluminum oxide pre-polish, in vibratory tumblers. When lapping, add the 400 and 1000 grits to the standard sequence.
