The Irwin 63908 is a titanium nitride coated jobber length drill bit designed for drilling in metal and other demanding materials. This 1/8 inch diameter bit is used with portable drills or stationary drill presses. The titanium nitride coating reduces friction, keeps the cutting edge sharper longer, and extends the overall life of the bit compared to uncoated alternatives.
When drilling repetitive holes in high tensile strength metals, this bit excels by reducing torque and feed pressure requirements. The 135 degree split point allows for easier penetration without work hardening or damaging the workpiece, while the rigid web construction provides exceptional stability and control in demanding applications.
Features and Benefits
- Titanium Nitride Coating: Reduces friction and keeps the cutting edge sharper longer, extending the life of the bit.
- 135° Split Point: Allows easier penetration without work hardening the material, reducing required feed pressure.
- Rigid Web Construction: Provides extreme rigidity and stability when drilling in metal applications, minimizing deflection.
- Heavy Duty Design: Shorter cutting lips reduce torque when drilling in high tensile strength materials, making operation easier.
- Jobber Length: Standard 2-3/4 inch overall length for general purpose drilling applications.
