Harder and more wear resistant than cobalt steel, these carbide bits create an accurate starting place in your workpiece. Cut an indent, then continue drilling with a longer bit. The indent prevents slipping so the final hole is centered and precise. Carbide stays sharp at high temperatures and faster speeds. It can be brittle, however, so these bits require a rigid machine tool holder to prevent breakage and should not be used in hand drilling applications.

Cut clean holes in abrasive material without fraying or delaminating the surface. Made of carbide, these bits resist wear to retain a sharp edge, even after after hundreds of cuts.
