Hertel 71205819 Jobber Length Drill Bit 11/32 Inch Hss

Product Description

The HERTEL 71205819 is a jobber length drill bit designed for general-purpose drilling in metal, wood, and plastic. It is manufactured from high speed steel with an oxide coating that helps reduce friction and extend tool life under normal operating conditions. The bit measures 11/32 inch (0.3438 inch decimal) in diameter with a standard 118-degree point angle and a right-hand spiral flute configuration. At 4-3/4 inches overall length with a 3-7/16 inch flute length, it fits standard drill chucks and press spindles used daily in fabrication, mechanical, and maintenance trade work.

This bit is suited for production and maintenance drilling applications in fabrication shops, mechanical rooms, and field service environments. The straight cylindrical shank accepts standard three-jaw chucks on both hand drills and drill presses. The regular spiral and tapered web with web thinning improve chip evacuation and reduce the thrust needed to start and complete a hole, making it practical for repetitive drilling tasks across a range of base materials.
