CARBIDE STRAIGHT FLUTE DRILL BITS FOR WORK-HARDENED STEELS (42–65 RC)
Carbide Straight Flute Drill Bits engineered for extreme applications where standard drills fail. Designed to cut through work-hardened steels, broken fasteners, and high-nickel alloys, these USA-made drills deliver maximum heat resistance, rigidity, and edge life in punishing conditions.
Manufactured from premium sub-micrograin solid carbide with a blended 10% cobalt binder, these drills feature exceptional toughness and thermal stability for high-temperature machining environments.
A 140° split point provides aggressive engagement with reduced walking—making these some of the best carbide drills available for drilling out broken bolts, frozen fasteners, and snapped extractors.
