Irwin 63928 Jobber Drill Bit, 7/16 in Dia, 5-1/2 in OAL, Spiral Flute, 2-Flute, 7/16 in Dia Shank, Straight Shank

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
• 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
