Hertel 71206775 Jobber Drill Bit No 60 Hss Oxide

Product Description

The HERTEL 71206775 is a jobber-length drill bit in wire gauge size No. 60, designed for precision drilling in metal, plastic, and similar materials. It is manufactured from high-speed steel with an oxide coating that reduces friction and provides basic corrosion resistance during operation. The bit measures 1.625 inches overall length with a flute length of 0.6875 inches, and features a standard 118-degree split-point angle with a web-thinned, tapered web configuration for improved centering and reduced thrust. The straight-cylindrical shank diameter matches the drill diameter at 0.0400 inches, making it compatible with standard drill chucks. This is a general-purpose bit suited for light-duty production and maintenance work.

This bit is used in applications requiring small-diameter precision holes, including instrument assembly, sheet metal fabrication, electronics enclosure work, and light mechanical repair. The No. 60 wire gauge size at 0.0400 inches decimal equivalent is commonly used for pilot holes, tap-drill operations for fine-thread fasteners, and through-hole placement in thin-gauge materials. It is intended for use in hand drills, drill presses, and CNC drilling equipment capable of accepting small-diameter straight-shank tooling. Right-hand spiral flute geometry provides standard chip evacuation suitable for most general-purpose drilling scenarios.

Key Features

• No. 60 wire gauge size, 0.0400 inches decimal equivalent diameter
• High-speed steel construction with oxide coating for reduced friction
• 118-degree standard point angle with web-thinned tapered web for improved centering
• Right-hand cut with 2-flute regular spiral for efficient chip removal
• Straight-cylindrical shank fits standard drill chucks and collets
• 1.625 inches overall length suitable for jobber-length drilling applications

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard drill chucks and collets accepting straight-cylindrical shanks at 0.0400 inches diameter.

Installation Notes

This bit is installed and operated by machinists, tool-and-die technicians, sheet metal workers, and maintenance professionals. Secure the straight shank firmly in the chuck before operation and verify runout on sensitive or tight-tolerance applications. Use appropriate cutting fluid or lubrication when drilling ferrous metals to extend tool life. At this diameter, feed pressure should be light and controlled to avoid bit deflection or breakage.
