    • 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
