Hertel 71206908 Jobber Drill Bit Wire 73 Hss Oxide

Product Description

The HERTEL 71206908 is a wire gauge size 73 jobber length drill bit designed for precision drilling in light-duty and general-purpose metalworking applications. The bit measures 0.0240 inches in diameter with an overall length of 1.125 inches and a flute length of 0.3125 inches. Constructed from high speed steel with an oxide coating, it delivers reliable performance when drilling through ferrous and non-ferrous metals, plastics, and similar materials. The 118-degree standard point angle and web-thinned tip geometry help reduce walking and improve bite during entry. This is a single-piece unit sold individually, with a minimum order quantity of 12.

This drill bit is suited for bench drilling, hand drilling, and machine drilling tasks where fine-diameter holes are required. At 0.0240 inches, the wire size 73 designation places this bit in the smallest range of jobber drill assortments, making it useful for printed circuit board drilling, instrument work, light sheet metal, and other precision applications. Machinists, tool and die technicians, and maintenance mechanics working on close-tolerance assemblies are the typical end users of this size range.

Key Features

• Wire gauge size 73 at 0.0240 inches diameter for fine-tolerance hole making
• High speed steel construction for use across general-purpose drilling applications
• Oxide coating provides surface hardness and mild corrosion resistance
• 118-degree standard point angle with web-thinned tip reduces entry force
• Spiral regular flute design with tapered web configuration for efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks

Compatibility

Designed as a general-purpose jobber length drill bit compatible with standard keyless and keyed drill chucks that accept straight-cylindrical shanks in the 0.0240-inch diameter range.

Installation Notes

This bit is installed by a machinist or maintenance technician into a compatible drill chuck on a drill press, CNC machine, or hand drill. Secure the shank firmly in the chuck before operation and verify concentricity to avoid bit deflection at this small diameter. Use appropriate cutting fluid for ferrous metals to extend bit life and reduce heat buildup. At this diameter, feed pressure must be controlled carefully to prevent bit breakage.
