Irwin 91164 Silver Deming Drill Bit 1 Inch Hss 6 Pack

Product Description

The IRWIN INDUSTRIAL TOOL CO 91164 is a 1-inch Silver Deming drill bit built from M-7 high speed steel for exceptional abrasion resistance during heavy-duty drilling applications. The bit measures 6 inches in overall length and features a 1/2-inch reduced shank that fits all standard 1/2-inch drill chucks. A 3-flatted shank design locks firmly in the chuck to minimize slippage during high-torque cuts. The 118-degree standard point geometry is suited for drilling into wood, metal, and plastic. This listing includes a package of 6 bits. Licensed tradespeople and skilled fabricators rely on this bit for creating large-diameter holes efficiently and accurately.

The 91164 is well suited for demanding environments including heavy-duty metal drilling, automotive repair, body shop work, and metal fabrication. The 1/2-inch reduced shank makes the bit compatible with the wide variety of 1/2-inch drills already in the field, eliminating the need for specialty tooling. The bit is also compatible with keyless chucks, allowing for fast bit changes on the job. Typical users include machinists, automotive technicians, body shop fabricators, and maintenance professionals who regularly drill oversized holes in steel, aluminum, and other metals.

Installation Notes

Silver Deming bits should be installed by securing the 3-flatted shank firmly in a 1/2-inch chuck before operation. Ensure the drill is powered off and unplugged or the trigger is locked out before changing bits. Use appropriate cutting fluid when drilling through steel or hard metals to extend bit life and reduce heat buildup. Wear proper eye protection and secure the workpiece before drilling.
