Titanium nitride coating reduces friction and last longer, cutting edge stays sharper longer. Used in repetitive metal drilling with portable drills or stationary drill press. Jobber length.

  • Titanium Nitride (TiN) coating resists heat and friction, providing up to 6X longer life than standard high-speed steel bits
  • Heavy-duty web design provides extreme rigidity when drilling in metal applications
  • 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
