Silicon Carbide 400 Fine Grit

Sale price $21.99 Regular price $176.25

These silicon carbide abrasives have sharp, hard grains for fast cutting. Smash those corners and points in the tumbler, wipe out saw marks on the lap, get those stones ready for some polish slurry. Use in tumblers, flat laps, sphere machines or wherever coarse and fine grinding grits are needed.

The standard grit sequence can be varied depending on material and need. Standard sequence for rotary tumblers is 60/90220 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.

  • 60/90 coarse ungraded grit available in 10# and 50# bulk packages
