Features

  • Constructed of M-35 5% cobalt high-speed steel for super abrasive resistance in tough metals
  • Heavy-duty spiral flute design produces faster chip ejection
  • Shorter cutting lips reduce torque for drilling in high tensile strength materials
  • 135 deg split point reduces feed pressure for easier penetration without work hardening and tip point ensures a true start and eliminates bit walking

Description
High-speed steel with M-35, 5% cobalt, for higher heat and abrasion resistance; heavy-duty web construction for strength and durability. Split point begins drilling immediately, minimizing bit walk when used in applications such as metal drilling, including heavy-duty abrasive alloy metal drilling on hardened steel (heat-treated).
