Irwin 63915 Titanium Drill Bit, Jobber Length, 15/64 In.

The Irwin 63915 is a titanium nitride–coated jobber length drill bit sized 15/64 inch in diameter, engineered for metal drilling with both portable drills and stationary drill presses. The titanium nitride coating reduces friction, extends tool life, and keeps the cutting edge sharper longer during repetitive drilling tasks, making it an economical choice for frequent use in metal applications.

This drill bit features a heavy-duty web design that provides extreme rigidity when drilling in hard metals. The 135-degree split-point geometry enables smoother starts and easier penetration with reduced feed pressure. The shorter cutting lips reduce torque when drilling in high-tensile-strength materials, helping to prevent work hardening during demanding applications.

Features and Benefits

• Titanium Nitride Coating: Reduces friction and extends bit life, keeping the cutting edge sharper longer for consistent performance across multiple drilling cycles.
• 135-Degree Split Point: Provides smoother starts and easier penetration without excessive feed pressure, reducing the risk of skidding or work hardening.
• Heavy-Duty Web Design: Reduces flex and allows smoother drilling of hard metals with extreme rigidity.
• Reduced Lip Length: Shorter cutting edges reduce torque when working with high-tensile-strength materials.
• Jobber Length: Standard length suitable for general-purpose drilling in metal with both handheld and stationary equipment.
