description: Milwaukee's one piece carbide tipped core bits are ideal for drilling large holes in brick, block, and concrete. The asymmetric tooth pitch with alternating tooth geometries for up to 20% faster drilling speeds. The one piece design maximizes energy transfer and the thick wall core body is durable in large hammers. The fluted core exterior minimizes friction loss and removes debris faster. Core bit cut with the outer cutting edge only. The inside core must be removed to allow for deeper hole drilling applications beyond 3\depth: 3
