Hertel 71206718 Jobber Drill Bit 54 Wire 0.0550 in Hss

Product Description

The HERTEL 71206718 is a wire gauge size 54 jobber length drill bit designed for general-purpose drilling in metal, plastic, and similar materials. It measures 0.0550 inches in diameter with a 1-7/8 inch overall length and a 7/8 inch flute length. The bit is machined from high speed steel and finished with an oxide coating that reduces friction and provides basic corrosion resistance during use. The 118-degree standard point angle and web-thinned tip promote accurate starting and reduce thrust requirements. With a straight-cylindrical shank, it seats securely in standard drill chucks. This bit is suited for machinists, maintenance technicians, and fabrication professionals working with small-diameter holes in light to medium-duty applications.

This drill bit fits into general-purpose drilling operations where wire gauge sizing is specified. Typical applications include pilot hole drilling, fixture work, sheet metal fabrication, and precision layout tasks in job shop, maintenance, and light manufacturing environments. The right-hand spiral flute design evacuates chips efficiently during through-hole and blind-hole drilling at standard spindle speeds appropriate for high speed steel tooling. Sold individually per package.

Key Features

• Wire gauge size 54, equivalent to 0.0550 inches decimal diameter
• High speed steel construction for general-purpose metal and plastic drilling
• Oxide coating reduces friction and provides basic surface protection
• 118-degree standard point angle with web-thinned tip for accurate starting
• Regular spiral, right-hand cut with two flutes for consistent chip evacuation
• Straight-cylindrical shank fits standard drill chucks without modification

Compatibility

Designed as a general-purpose jobber length drill bit suitable for use in standard drill presses, CNC drilling machines, and hand drills equipped with chucks accepting a 0.0550 inch straight-cylindrical shank.

Installation Notes

Secure the shank fully in the chuck before operation and verify runout is within acceptable limits for small-diameter tooling. Use cutting fluid or light oil when drilling ferrous metals to extend tool life and improve hole finish. Reduce feed pressure on breakthrough to prevent bit deflection or breakage at this diameter. Small-diameter bits are susceptible to breakage from lateral load — maintain alignment between the spindle axis and the workpiece.
