Hertel 85703791 Jobber Length Drill Bit Wire Size 2

Product Description

The HERTEL 85703791 is a jobber-length drill bit in wire gauge size 2, with a decimal diameter of 0.2210 inches. Manufactured from high speed steel with a bright, uncoated finish, it is designed for general-purpose drilling in metal, wood, plastics, and similar materials. The standard 118-degree point angle suits a wide range of common drilling applications. At 3-7/8 inches overall length with a 2-5/8-inch flute length, this bit fits the standard jobber form factor used across most chuck-equipped drill presses and hand drills found in industrial and maintenance environments.

This bit is suited for production shops, maintenance and repair operations, fabrication facilities, and field service work where wire-gauge-sized holes are required. The straight-cylindrical shank seats directly in standard 3-jaw chucks without adapters. Right-hand cut geometry is compatible with conventional clockwise-rotation drilling equipment. The regular spiral and tapered web configuration with web thinning improves chip evacuation and reduces thrust on entry, making it practical for both hand-held and machine-mounted applications.

Installation Notes

Installation and use should be performed by qualified machinists, maintenance technicians, or trade professionals familiar with rotary cutting tool safety. Secure the shank fully in the chuck before operating and verify chuck key is removed prior to powering the drill. Wear appropriate eye protection and secure workpieces with clamps or a vise rather than holding by hand. Inspect the cutting edges for wear or damage before each use and replace bits that show chipping or heat discoloration.
