M35 Cobalt Drill Bits Set for Hardened Metals with TiAlN
✔️ Three-flute TiAlN coated, 21-piece set from 1/16" to 1/2"

Engineered for tough metals, this 21-piece drill bit set uses M35 cobalt steel and a TiAlN coating to cut through stainless steel, hardened cast iron, titanium alloys, and high-carbon steel. The sizes range from 1/16" to 1/2" to cover common metalworking tasks in shops, fabrication floors, and repair operations.

✅ M35 cobalt steel with 5% cobalt delivers hard cutting performance up to 60 HRC
✅ TiAlN coating withstands heat up to 1472°F (800°C), extending tool life
✅ Triple-flute design improves chip evacuation, hole quality, and drilling speed
✅ Three-flat shank ensures zero-slip grip in high-torque drills
✅ 21-piece set covers sizes 1/16"-1/2" for most metal drilling tasks
