Irwin IR60524 Hss Jobber Drill Bit 3/8 Inches 118 Degree

Product Description

The IRWIN IR60524 is a high speed steel jobber-length drill bit sized at 3/8 inches in diameter. It is designed for general-purpose drilling in metal, wood, and plastic, making it a standard tool on commercial and industrial job sites as well as in trade service vans. The 118-degree standard point angle provides a self-centering entry suitable for a wide range of materials. With an overall length of 5 inches and a flute length of 3.625 inches, this bit fits standard 3/8-inch and 1/2-inch keyed or keyless chucks. The straight shank ensures compatibility with most portable drill drivers and drill presses used by electricians, plumbers, HVAC techs, and general contractors.

This bit is suited for jobber-length drilling tasks encountered across electrical, plumbing, HVAC, and mechanical trades. It handles typical penetrations through sheet metal, framing lumber, plastic conduit bodies, and similar substrates found in residential and light commercial work. The jobber length designation means the flute-to-diameter ratio follows standard proportions, giving a balance of rigidity and reach appropriate for hand-held drilling operations.

Installation Notes

Secure the straight shank firmly in the chuck before operation and verify the bit runs true before drilling under load. Use appropriate cutting fluid when drilling hardened steel or cast iron to extend bit life and reduce heat buildup. Always wear eye protection and secure the workpiece. Follow applicable OSHA and site safety requirements when operating rotary drilling tools.
