Hertel 85707719 Jobber Drill Bit Wire 47 Hss Tin

Product Description

The HERTEL 85707719 is a jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastic. Built from high speed steel with a titanium nitride (TiN) coating, it resists wear and runs at higher surface speeds than uncoated HSS tooling. The bit is wire gauge size 47, with a decimal diameter of 0.0785 inches and an overall length of 2 inches. A 118-degree standard point angle and spiral flute geometry provide clean entry and efficient chip evacuation. The straight-cylindrical shank seats securely in standard drill chucks across keyed and keyless designs.

This bit suits light-duty production and maintenance drilling tasks in fabrication shops, HVAC service work, and general mechanical assembly. The 2-inch overall length and 1-inch flute length make it appropriate for shallow-hole applications where a compact tool is needed. The web-thinned, tapered web configuration reduces the thrust required to start the cut, which is useful when working with hand drills or low-torque benchtop drill presses. It is sold individually and is intended for machinists, tradespeople, and maintenance technicians who need a reliable small-diameter bit.

Key Features

• Wire gauge size 47 with 0.0785 inch decimal diameter for precise small-bore drilling
• TiN coating extends tool life and reduces friction at the cutting edge
• 118-degree standard point angle for general-purpose material compatibility
• Web-thinned tapered web lowers drilling thrust and improves bit starting
• Spiral regular flute with right-hand cut for conventional drill operation
• Straight-cylindrical shank fits standard 3-jaw drill chucks without adapters

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard drill chuck that accepts a 0.0785 inch straight-cylindrical shank.

Installation Notes

Install and remove drill bits only when the drill or drill press is fully powered off and the chuck has stopped rotating. Secure the shank fully into the chuck jaws and tighten with a chuck key or by hand-tightening a keyless chuck before operation. Use appropriate cutting fluid or coolant when drilling ferrous metals to extend tool life. Wear eye protection in accordance with applicable shop safety requirements.
