This DeWALT Power Tools Extreme Metal Drill Bit set is designed for precise drilling in steel, alloyed and non-alloyed metals up to 900N/mm. The bits feature a patented split pilot point design that prevents walking or slipping upon contact, making them particularly effective for creating accurate, burr-free holes in sheet metal and thin materials. In addition to metalworking, these versatile drill bits perform effectively when used on wood and plastic, suitable for both portable and stationary drilling applications.
