Hertel 85703536 Jobber Drill Bit 11/32 in Hss

Product Description

The HERTEL 85703536 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastic. Built from high speed steel (HSS) with a bright uncoated finish, it features a 118-degree standard point angle and a web-thinned, tapered web construction that reduces thrust and improves chip clearance at entry. The bit measures 11/32 inch (0.3438 inch decimal) in diameter with an overall length of 4-3/4 inches and a flute length of 3-7/16 inches. The straight-cylindrical shank seats securely in standard drill chucks. With two spiral flutes in a regular helix, chips evacuate cleanly during through-hole and blind-hole operations.

This bit suits light to medium fabrication, HVAC sheet metal work, plumbing rough-in, electrical panel drilling, and general maintenance drilling tasks. The 11/32-inch diameter is a common size for conduit knockouts, anchor bolt clearance holes, and pilot holes across a range of trade applications. It is sized within the 0.3000 to 0.3500 inch decimal range and is sold individually, though the minimum order quantity is 6 pieces per purchase.

Compatibility

Designed as a general-purpose replacement or stock drill bit for any standard drill press or hand drill accepting a straight-cylindrical shank in the 11/32-inch size range.

Installation Notes

Install and remove drill bits only when the drill or drill press is fully powered down and the chuck is stationary. Secure the shank fully into the chuck jaws and tighten with a chuck key before operation. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and reduce heat buildup. Wear ANSI-rated eye protection during all drilling operations per standard shop safety practice.
