Irwin 63904 Titanium Jobber Drill Bit 1/16 Inches 3 Pack

Product Description

The IRWIN INDUSTRIAL TOOL CO 63904 is a 1/16-inch titanium jobber-length drill bit sold in a pack of three. Coated with titanium nitride, the bit is engineered for extended service life in metal drilling applications. The heavy-duty web design delivers extreme rigidity under load, while shorter cutting lips reduce torque when working through high-tensile-strength materials. A 35-degree split point lowers feed pressure for faster, cleaner penetration without work hardening the material. Licensed electricians, plumbers, HVAC techs, and general trade professionals reach for this bit when precision holes in metal are required on the job.

The 63904 is suited for jobber-length drilling tasks in residential and light commercial settings. Its 1/16-inch diameter makes it appropriate for pilot holes, small clearance holes, and detail work in sheet metal, structural steel, and similar high-tensile materials. The titanium nitride coating reduces heat buildup during continuous use, making this bit a practical choice for repetitive drilling cycles common in trade work. Each pack contains three bits, providing backup on the job without requiring a separate reorder.

Installation Notes

Installation is performed by trade professionals using standard drill drivers or drill presses. Secure the bit firmly in the chuck before use and confirm the chuck key is removed before powering the tool. When drilling metal, use appropriate cutting fluid or lubricant to manage heat and extend bit life. Wear proper eye protection in compliance with applicable job-site safety requirements.
