Irwin 67524 3/8 Inch Black Oxide Jobber Drill Bit 5 Pack

Product Description

The IRWIN INDUSTRIAL TOOL CO 67524 is a 3/8-inch heavy-duty jobber-length drill bit constructed from M-2 high speed steel. M-2 HSS delivers a reliable balance of strength, heat resistance, and wear resistance for demanding trade applications. A black oxide coating is applied to the surface to resist corrosion and extend service life. The 135-degree split point geometry provides a self-centering start and eliminates bit walking on smooth or curved surfaces. Sold in a 5-pack, this bit is suited for frequent use across a range of materials.

This drill bit is designed for general-purpose drilling in wood, metal, and plastic. It is appropriate for residential and light commercial work where a reliable, multi-material bit is needed. Electricians, plumbers, HVAC technicians, and general contractors commonly keep jobber-length bits in this diameter on hand for framing penetrations, panel work, and fixture installation. The standard jobber length fits most 3/8-inch and larger keyed or keyless chucks.

Installation Notes

Ensure the drill chuck is fully tightened before operation. When drilling into metal, apply cutting fluid or lubricant to reduce heat buildup and extend bit life. Reduce feed pressure as the bit breaks through the back side of the material to prevent grab or breakage. Wear appropriate eye protection per job site safety requirements.
