Hertel 85703460 Jobber Drill Bit 15/64 Inch Hss

Product Description

The HERTEL 85703460 is a jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastics. It is manufactured from high speed steel with a bright, uncoated finish and features a standard 118-degree point angle with web thinning for easier penetration and reduced thrust. The straight-cylindrical shank measures 15/64 inch in diameter and fits standard three-jaw chucks. With an overall length of 3-7/8 inches and a flute length of 2-5/8 inches, this bit suits bench drill presses, hand drills, and drill drivers used in fabrication, maintenance, and mechanical service work.

This bit is suited for general-purpose drilling applications in light manufacturing, HVAC fabrication, plumbing rough-in, and electrical trade work. The 15/64-inch diameter is commonly used for clearance holes, pilot holes, and tapping preparation in mild steel, aluminum, and similar materials. The right-hand spiral flute configuration clears chips efficiently during through-hole drilling. It is sold individually and is appropriate for contractors and tradespeople who need a reliable stock diameter on hand for everyday shop and field use.
