Irwin 91152 Black Oxide Drill Bit 13/16 in 118 Degree

Product Description

The IRWIN 91152 is a black oxide twist drill bit designed for general-purpose drilling in metal, wood, and plastic. The 13/16-inch diameter and 118-degree split point geometry allow for fast, accurate starts without a center punch, reducing walking on entry. Black oxide coating provides mild lubrication and corrosion resistance, extending tool life in high-cycle shop and field use. This bit is a standard item for electricians, plumbers, HVAC technicians, and general tradespeople who need reliable, repeatable hole quality in a common diameter.

The 91152 fits standard 13/16-inch drilling applications encountered in trade work, including conduit entry holes, pipe rough-in, and bracket fabrication. It is sold individually and suits any drill or drill press accepting a standard straight shank at this diameter. The 118-degree point angle is appropriate for a wide range of common materials found on residential and light commercial job sites.

Key Features

• 13/16-inch diameter for common trade drilling applications
• 118-degree split point for self-starting entry and reduced thrust
• Black oxide finish for lubrication and mild corrosion resistance
• Straight shank compatible with standard chucks and drill presses
• Sold as individual unit (each)

Compatibility

Designed as a standard straight-shank twist drill bit compatible with any drill or drill press chuck sized to accept a 13/16-inch shank.

Installation Notes

Twist drill bits at this diameter should be installed in a properly rated drill or drill press by a qualified tradesperson. Ensure the chuck is fully tightened before operation and use appropriate cutting fluid when drilling ferrous metals to extend bit life. Eye protection is required during use per standard shop safety practice.
