Hertel 85703445 Jobber Drill Bit 13/64 Inch Hss

Product Description

The HERTEL 85703445 is a jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastic. Built from high speed steel with a bright uncoated finish, it delivers reliable performance across a wide range of shop and field applications. The 118-degree standard point angle allows for easy starting on flat and curved surfaces without center-punching in many setups. At 3.625 inches overall length with a 2.4375-inch flute length, it fits standard drill chucks and magnetic drill presses. Machinists, millwrights, pipefitters, and general tradespeople keep this size stocked for layout and field work.

This bit is suited for light to medium-duty drilling in ferrous and non-ferrous materials. The 13/64-inch diameter, equivalent to 0.2031 inches decimal, is a common size used for clearance holes, tapping pilots, and general hole-making tasks in fabrication shops, mechanical rooms, and job-site conditions. The straight cylindrical shank seats securely in keyed or keyless chucks. The regular spiral flute geometry and tapered web configuration support efficient chip evacuation in through-hole and blind-hole drilling operations.

Key Features

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard keyed or keyless drill chuck accepting a straight cylindrical shank in the 13/64-inch diameter range.

Installation Notes

This bit is installed and used by machinists, pipefitters, electricians, and general tradespeople using handheld drills or drill presses. Secure the shank fully in the chuck before operation and verify chuck tightness. Use appropriate cutting fluid when drilling hard metals to extend tool life and reduce heat buildup. Wear eye protection and follow applicable shop safety procedures during all drilling operations.
