Irwin IR73828 Hss Drill Bit 7/16 in Jobbers Length

Product Description

The IRWIN IR73828 is a high speed steel (HSS) jobbers-length drill bit designed for general-purpose drilling in metal, wood, and plastic applications. It features a 7/16-inch drill diameter, a 5.5-inch overall length, and a 4.0625-inch flute length. The 118-degree standard point angle provides reliable centering on most common materials without requiring a pilot hole. The reduced 3/8-inch shank allows this bit to seat in standard 3/8-inch chucks, making it compatible with a wide range of corded and cordless drills used in the trade. Machinists, pipefitters, electricians, and general contractors reach for jobbers-length HSS bits as a go-to for everyday hole-making tasks.

This bit is suited for residential and commercial applications where a versatile, mid-length drill bit is needed. The jobbers-length format balances reach and rigidity, making it practical for drilling through structural framing, conduit hangers, pipe flanges, sheet metal, and similar trade materials. The reduced shank design broadens chuck compatibility, allowing use with 3/8-inch capacity drill drivers commonly found on job sites. It is sold individually (each), making it easy to replace a single worn bit without purchasing a full set.

Installation Notes

This bit is installed by trade professionals including electricians, plumbers, pipefitters, and HVAC technicians for everyday drilling tasks. Secure the reduced shank fully into a 3/8-inch or larger drill chuck before operation and verify the chuck is tightened to prevent slippage. Use appropriate cutting fluid when drilling through hardened metals to extend bit life and reduce heat buildup. Follow applicable safety codes and wear appropriate eye protection during all drilling operations.
