Irwin 63908 Titanium Drill Bit 1/8 Inch 2 Pack

Product Description

The IRWIN INDUSTRIAL TOOL CO 63908 is a 1/8 inch titanium nitride coated jobber length drill bit sold in a 2-pack. Titanium nitride coating bonds to the high-speed steel substrate to extend cutting life compared to uncoated bits. The heavy duty web design adds rigidity through the body of the bit, which is critical when driving into metal. A 35-degree split point initiates the cut without a center punch, reducing feed pressure and preventing work hardening at the entry point. Shorter cutting lips lower the torque demand when working through high tensile strength materials.

These bits are suited for metal drilling applications in trade and light industrial settings. Electricians, plumbers, HVAC techs, and sheet metal workers reach for jobber length bits when drilling through steel brackets, panels, pipe hangers, and structural members. The 1/8 inch diameter is a common pilot and clearance size for fasteners and conduit anchors. The 2-pack format supports continuous workflow when one bit is in use or needs to be swapped out on a busy job.

Key Features

• Titanium nitride coating extends bit life over standard uncoated high-speed steel
• Heavy duty web design provides extreme rigidity during metal drilling
• 35-degree split point reduces feed pressure and eliminates work hardening at entry
• Shorter cutting lips reduce torque requirements in high tensile strength materials
• Jobber length format fits standard drill chucks and quick-change holders
• 2-pack quantity keeps a spare ready on the job

Compatibility

Designed for use with standard 3-jaw drill chucks and quick-change chuck systems accepting 1/8 inch round shank jobber length bits. Suitable for drilling mild steel, aluminum, and similar metals common in trade applications.

Installation Notes

These bits are installed and changed by electricians, HVAC technicians, plumbers, and general trade mechanics using corded or cordless drills. Ensure the drill chuck is fully tightened before operation and that workpieces are secured to prevent movement. When drilling metal, apply consistent feed pressure and use cutting fluid on thicker stock to extend bit life. Inspect the cutting tip before each use and replace any bit showing tip damage or reduced cutting performance.
