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.
