Hertel 85703734 Jobber Drill Bit 21/32 Inch Hss

Product Description

The HERTEL 85703734 is a jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastic. It measures 21/32 inches (0.6562 inches decimal) in diameter with an overall length of 7-1/8 inches and a flute length of 5-3/16 inches. The bit is manufactured from high speed steel with a bright, uncoated finish and features a standard 118-degree split point with web thinning for reduced thrust and easier starting. The straight-cylindrical shank seats securely in standard drill chucks. This bit is suited for use by machinists, pipefitters, electricians, and general trade professionals requiring a reliable general-purpose cutting tool.

This jobber-length bit is appropriate for through-hole and stepped drilling operations in light manufacturing, maintenance, and field service applications. The regular spiral flute geometry promotes chip evacuation during drilling. The 21/32-inch diameter is commonly used when opening knock-outs, sizing conduit holes, or drilling clearance holes for fasteners. Right-hand cutting direction is standard for use in conventional drill presses, hand drills, and magnetic drills. Sold individually as a single-piece unit.
