The Dremel solid carbide cutting bit features a 3/16" shank. It is ideal for cutting soft wood, hardwood, plywood, composites, laminate and metal sheet, engineered flooring, drywall, acoustic tile, plastics, fiberglass, vinyl siding and aluminium. Carbide bits easily cut through hard woods, like oak and walnut, as well as 22 gauge (and lower) steel. When cutting wood, solid carbide cutting bits last five-times longer than standard multi-purpose bits. This bit is designed specifically for the Dremel Trio tool.
