Rubber-Cushioned Abrasive Grinding Bits for Metals
The abrasive grains in these bits are blended with rubber, which cushions during grinding to produce a smoother surface texture than other bits with similar grits. Bits are also known as mounted points and die grinder bits. Head diameter is measured at the widest point.
Bits for aluminum, brass, and bronze are silicon carbide, which cuts through soft metals without generating much heat or causing material buildup.
Caution: As bit shank is exposed beyond 1/2", maximum safe rpm decreases significantly. Refer to ANSI standard B7.1. Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

Miniature Dremel-Compatible Cutoff Wheels for Ceramics
Made of diamond abrasive, these wheels cut ceramics, tile, and other abrasive materials. Because they’re miniature, they work best to make small, precise cuts. Use them to make plunge cuts in the center of material or to make flush cuts. The higher the grit number, the finer the grit. Choose a coarser grit for fast cuts; choose a finer grit for smooth cuts.
Warning: Use wheels that have a greater rpm rating than the no-load rpm of your tool.
