#1 – #35 Terminator Straight Flute Carbide XF SERIES
CARBIDE STRAIGHT FLUTE DRILL BITS FOR HARDENED STEEL (42–65 HRC)
Solid Carbide Straight Flute Drill Bits engineered for extreme applications where standard HSS and cobalt drills fail. Designed to drill hardened and work-hardened steels, broken bolts, broken taps, snapped screw extractors and Easy-Outs, heat-treated steels, stainless steel, titanium, nickel alloys, and other difficult-to-machine materials.
These USA-made carbide drills deliver exceptional heat resistance, rigidity, and cutting-edge life in demanding production, maintenance, and repair applications. Also widely used in aerospace, defense, medical, and precision machining applications where tool rigidity and performance in difficult materials are critical.
A 140° split point provides aggressive engagement with reduced walking—making these an excellent choice for drilling out broken bolts, frozen fasteners, hardened studs, snapped extractors, and broken taps.
