The DART range of HSS drill bits features precision-engineered, high-speed steel drill bits, ideal for drilling into metal surfaces. The tip is designed to cut the material, while the spirals work to remove debris from the hole. Our HSS drills include Cobalt, TiN Coated, Ground, and Rolled, plus a range of Stub, Long Series and Reduced Shank Blacksmith drill bits. From excellent resistance to heat and wear in the Cobalt and TiN coated series to HSS ground split point, these drill bits are the perfect choice for drilling in a wide range of applications.
