Titanium Nitride-Coated
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
