Hertel 85704187 Jobber Drill Bit Wire 41 Hss 118 Degree

Product Description

The HERTEL 85704187 is a jobber-length drill bit designed for general-purpose drilling in a wide range of materials. Built from high speed steel with a bright uncoated finish, this bit is sized to wire gauge number 41, which corresponds to 0.0960 inches in decimal. It features a 118-degree standard point angle with web thinning on a tapered web, which reduces entry force and helps center the bit on the workpiece. The straight-cylindrical shank measures 0.0960 inches in diameter, and the overall length is 2.375 inches with a flute length of 1.375 inches. Two spiral flutes in a regular helix clear chips efficiently during right-hand cutting operations.

This bit is suited for light-duty through-hole and blind-hole drilling in metal, plastic, and wood. The wire gauge 41 size is commonly used in machining, maintenance, and fabrication work where precise small-diameter holes are required. The jobber-length format provides a practical balance between reach and rigidity for bench drill press and hand drill applications. This size range is typical in sheet metal work, electronics assembly support drilling, and general mechanical maintenance performed by machinists, millwrights, and maintenance technicians.

Key Features

Compatibility

Designed as an OEM-style jobber-length drill bit for use in standard drill presses, CNC drilling machines, and hand drills equipped with chucks accepting a 0.0960-inch straight shank.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with drill press and hand drill operation. Secure the shank fully in the chuck and verify concentricity before running at speed. Power down and de-energize any machine before changing bits. Use appropriate cutting fluid or lubrication for the material being drilled to extend bit life and maintain hole quality.
