The Irwin TurboMax 1/2" drill bit features a 3/8" reduced shank that fits standard 3/8" drill chucks, letting you drill larger holes without upgrading your drill. The Jet Point tip design starts fast without walking and stays sharp longer than conventional HSS bits. TurboMax bits are engineered to drill more holes, faster, than standard high-speed steel bits.
