Hertel 71206965 Jobber Drill Bit Wire 79 Hss Oxide

Product Description

The HERTEL 71206965 is a wire gauge size 79 jobber length drill bit designed for precision drilling in tight-tolerance applications. Manufactured from high speed steel with an oxide coating, this bit measures 0.0145 inches in diameter with an overall length of 0.75 inches and a flute length of 0.125 inches. The 118-degree standard drill point angle and two-flute spiral configuration provide clean entry and efficient chip evacuation. It is sold individually and is intended for installation and fabrication professionals working in metalworking, electronics, and light manufacturing environments.

Wire gauge drill bits in this size range are commonly used by machinists, electronics technicians, and tool-and-die professionals for drilling small pilot holes, clearance holes, and precision through-holes in thin metals, circuit boards, and plastics. The number 79 wire size corresponds to a 0.0145-inch decimal diameter, placing it in the very fine end of the standard wire gauge drill series. This bit is appropriate for bench drill press work or hand-held rotary tool use where controlled feed pressure is essential to prevent breakage at this diameter.

Key Features

• Wire gauge size 79 at 0.0145 inch decimal diameter for fine precision drilling
• High speed steel construction provides hardness and wear resistance for general-purpose metalworking
• Oxide coating reduces friction and provides light corrosion resistance during use
• 118-degree standard point angle suits a broad range of workpiece materials
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Web-thinned, tapered web configuration reduces thrust required at entry

Compatibility

Designed as a general-purpose jobber length drill bit suitable for use in standard drill presses, CNC drilling centers, and rotary hand tools equipped with chucks or collets accepting a 0.0145-inch straight-cylindrical shank.

Installation Notes

This bit should be installed by a qualified machinist or technician familiar with small-diameter tooling. Secure the shank fully in the chuck or collet and verify runout before drilling. Use low spindle speeds and light, consistent feed pressure to avoid bit deflection or breakage at this diameter. Always wear appropriate eye protection when operating rotary cutting tools.
