Hertel 71205843 Jobber Drill Bit 25/64 Inch Hss Oxide

Product Description

The HERTEL 71205843 is a jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastic. The bit measures 25/64 inch (0.3906 inch decimal) in diameter with a 5-1/8 inch overall length and a 3-3/4 inch flute length. It is manufactured from high speed steel with an oxide coating that helps reduce friction and extend tool life under normal shop conditions. The 118-degree standard point angle suits a wide range of common materials. A straight-cylindrical shank allows direct chuck mounting in standard drill presses and hand drills. This bit is suited for machinists, pipefitters, sheet metal workers, and general maintenance technicians working in shop or field environments.

This jobber-length drill bit fits into general fabrication, maintenance, and installation workflows where a reliable, right-hand-cut bit is needed for through-holes and clearance holes in everyday materials. The 25/64 inch diameter falls in the 0.3500 to 0.4000 inch size range, making it a common choice for bolt clearance, anchor prep, and conduit or pipe fitting work. It installs in any standard 3-jaw or keyed chuck accepting a straight shank in the corresponding diameter.
