Carbide-Tipped Drill Bits for Hardened Steel
The straight flutes and notched point withstand the heavy pressure necessary to penetrate hard steel. These carbide-tipped bits maintain their sharp edges when drilling abrasive material. Because they aren’t as brittle as solid carbide bits, they can be used in less rigid setups, such as a hand-held drill. They are jobbers' length and have the rigidity and length required for most hand-held drilling and machine tool applications.
