Silicon Carbide Wheel Points

Tougher than aluminum oxide bits, Dremel's silicone carbide grinding stones are designed for use on hard materials such as glass, ceramics, stone, porcelain and non-ferrous metals. Ideal for sharpening, deburring and for general purpose grinding and for projects like removing stilt marks, clearing excess glaze on ceramics, and glass engraving. The 9/32 In. (7.1 mm) flame shape of the grinding stone can be used on conic and flat surfaces.
