Hertel 85707362 Jobber Drill Bit Wire 14 0.182 in Tin Hss

Product Description

The HERTEL 85707362 is a jobber length drill bit designed for general-purpose metal drilling applications. It is manufactured from high speed steel with a titanium nitride (TiN) coating that extends cutting life and reduces friction at the cutting edge. The bit is sized to wire gauge number 14, corresponding to 0.1820 inch decimal diameter. It features a standard 118-degree split point, a two-flute spiral configuration with a tapered web, and a straight-cylindrical shank. Overall length is 3-3/8 inches with a flute length of 2-3/16 inches. Machinists, maintenance technicians, and trade professionals install this bit in standard drill presses, hand drills, and CNC equipment for through-hole and starter-hole work.

This drill bit is suited for ferrous and non-ferrous metals, plastics, and general construction materials in both shop and field environments. The regular spiral flute geometry promotes chip evacuation during drilling, which reduces heat buildup and helps maintain hole quality. The web-thinned point reduces the force required to start the cut and minimizes walking on harder materials. It is a single-piece, single-quantity item appropriate for replacement or stock use in maintenance and repair operations.

Key Features

• Wire size 14 diameter, 0.1820 inch decimal equivalent
• TiN coating for increased surface hardness and reduced cutting friction
• 118-degree standard point angle with web thinning for easier starts
• Two-flute regular spiral with tapered web for consistent chip removal
• Straight-cylindrical shank fits standard drill chucks without adapters
• 3-3/8 inch overall length with 2-3/16 inch flute length

Compatibility

Designed as a general-purpose jobber length drill bit compatible with standard drill presses, hand drills, and CNC equipment accepting straight-cylindrical shanks in the 0.1500 to 0.2000 inch diameter range.

Installation Notes

This bit is installed by machinists and maintenance technicians using standard drill chucks. Secure the shank fully in the chuck before operation and confirm the chuck key is removed before starting the spindle. Use appropriate cutting fluid or coolant when drilling harder metals to preserve coating life. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed to maintain hole tolerance and finish quality.
