Irwin 63920 5/16 in Titanium Jobber Drill Bit 3-pack

Product Description

The IRWIN INDUSTRIAL TOOL CO 63920 is a 5/16-inch titanium jobber length drill bit engineered for metal drilling applications. It features a titanium nitride coating that extends service life by reducing friction and heat buildup at the cutting edge. The heavy-duty web design delivers extreme rigidity under load, while shorter cutting lips lower torque demand when working through high tensile strength materials. A 35-degree split point reduces feed pressure for cleaner entry without work hardening the surrounding material. This package contains 3 bits, sold as a unit. Licensed tradespeople and experienced metalworkers are the primary users.

This drill bit is suited for drilling into steel, iron, and other high tensile strength metals in both shop and field settings. The jobber length format fits standard drill chucks and is compatible with corded and cordless drills used in HVAC, mechanical, electrical, and general fabrication work. The titanium nitride coating makes it a practical choice for repetitive drilling tasks where bit longevity matters. The 3-pack format supports job-site use where multiple setups run simultaneously.

Installation Notes

Installation of this bit is performed by any trade professional using a standard drill. Secure the bit firmly in the chuck before operation and verify chuck tightness before each use. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and reduce heat. Follow shop safety practices including eye protection and secure workpiece clamping.
