Hertel 85707701 Jobber Drill Bit Wire 46 Hss Tin

Product Description

The HERTEL 85707701 is a jobber-length twist drill bit designed for general-purpose metal drilling in production and maintenance applications. Ground from high speed steel (HSS) and finished with a titanium nitride (TiN) coating, it handles the heat and abrasion typical of repetitive drilling in steel, aluminum, brass, and similar materials. The wire gauge size is 46, corresponding to a decimal diameter of 0.0810 inches. Overall length is 2.125 inches, with a flute length of 1.125 inches. The 118-degree standard point angle is a proven all-purpose geometry suited to a wide range of workpiece materials. Machinists, tool-and-die workers, and maintenance technicians are the primary users.

This bit fits standard drill presses, hand drills, and CNC drilling operations where a straight-cylindrical shank is appropriate. The 0.0810-inch shank diameter matches the drill diameter, making it compatible with standard collets and Jacobs-style chucks sized for small-diameter tooling. Typical applications include pilot holes, through-holes in sheet metal and structural steel, and precision location drilling in light manufacturing and repair environments. The general-purpose grade makes it a practical stock item for high-turnover tooling inventories.

Key Features

• Wire size 46 (0.0810 inches decimal) for precise small-diameter hole work
• TiN coating extends tool life by reducing friction and surface heat
• 118-degree standard point angle suits a broad range of materials
• Web-thinned, tapered web reduces thrust force at entry
• 2-flute regular spiral geometry promotes chip evacuation
• Straight-cylindrical shank fits standard chucks and collets

Compatibility

Designed as an OEM-style jobber drill bit for use in any standard drill press, hand drill, or CNC spindle accepting a straight-cylindrical shank at 0.0810 inches diameter.

Installation Notes

Secure the shank fully in the chuck and verify runout before drilling. Always power down and de-energize or lock out the machine before changing tooling. Use appropriate cutting fluid or coolant for the workpiece material to maximize bit life, particularly in steel. Dispose of worn tooling per shop safety procedures to avoid handling sharp flute edges.
