Extended-Length Carbide-Tipped Drill Bits with Coolant Holes
Also known as gun drills, use these bits to drill long, straight holes. A hole in the bit allows coolant to be channeled through the tool for more efficient chip evacuation. More wear resistant than cobalt steel and high-speed steel, these carbide-tipped bits maintain a sharper, harder edge at high temperatures for excellent performance on abrasive material.
