Irwin IR73829 Hss Jobber Drill Bit 29/64 in 3/8 in Shank

Product Description

The IRWIN IR73829 is a high speed steel jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastics. Built to jobber-length proportions, it offers a practical reach-to-rigidity balance suited for bench-top drill presses and hand-held power drills. The cutting diameter is 29/64 inches with a 3/8 inch reduced shank, allowing it to seat in standard 3/8 inch chucks without requiring a larger chuck capacity. A bright finish indicates an uncoated HSS construction, which is appropriate for lower-heat applications and easy edge inspection during bit maintenance.

This bit is intended for trade and industrial use in light fabrication, HVAC rough-in, plumbing rough-in, and electrical work where accurate through-holes in steel plate, copper, aluminum, or wood are required. The reduced shank design makes it compatible with standard 3/8 inch chucks found on common cordless and corded drills, expanding its usability across a wide range of job site tools without special adapters.

Key Features

• Cutting diameter of 29/64 inches for precise hole sizing
• 3/8 inch reduced shank fits standard 3/8 inch drill chucks
• High speed steel construction for durability in metal and wood drilling
• Jobber-length geometry balances reach and rigidity for accurate drilling
• Bright finish allows easy visual inspection of cutting edges

Compatibility

Designed as an OEM-style replacement or direct addition for standard 3/8 inch chuck drill presses and hand-held power drills used in light fabrication and trade rough-in applications.

Installation Notes

Installation is performed by any trade professional using a 3/8 inch or larger chuck drill or drill press. Ensure the chuck is fully tightened before operation and that the workpiece is secured to prevent movement. Use appropriate cutting fluid when drilling through ferrous metals to extend bit life and reduce heat buildup. Follow applicable OSHA and site safety requirements for rotating tool use.
