Hertel 84578822 Jobber Drill Bit No. 60 Hss Tin

Product Description

The HERTEL 84578822 is a wire gauge No. 60 jobber-length drill bit designed for general-purpose drilling in metal, plastic, and similar materials. Manufactured from high speed steel with a titanium nitride (TiN) coating, the bit delivers improved surface hardness and extended cutting life compared to uncoated HSS tooling. At 0.0400 inches in diameter and 1.625 inches overall length, this bit is sized for precision small-diameter work. The 118-degree standard point angle suits a wide range of materials and is compatible with most bench and handheld drill setups. Two spiral flutes with a regular helix clear chips efficiently during through-hole and blind-hole operations.

This bit is suited for light manufacturing, maintenance and repair, sheet metal work, and precision assembly applications where small-diameter holes are required. The straight-cylindrical shank accepts standard three-jaw drill chucks without modification. The web-thinned, tapered web configuration reduces thrust at entry and improves centering on flat and curved surfaces. Machinists, tool-and-die technicians, and maintenance mechanics will find this bit appropriate for bench drill press and handheld drill use in shop and field settings.

Installation Notes

This bit is intended for use by machinists, maintenance technicians, and trade professionals operating drill presses or handheld drills. Secure the straight-cylindrical shank firmly in the chuck before operation and verify chuck key is removed prior to startup. Use appropriate cutting fluid or lubricant when drilling metal to extend tool life and maintain dimensional accuracy. Wear appropriate eye protection and follow applicable shop safety protocols when operating drilling equipment.
