Hertel 85707693 Jobber Drill Bit Wire 45 Hss Tin 0.082in

Product Description

The HERTEL 85707693 is a jobber length twist drill bit designed for general-purpose drilling in metal, wood, and plastic. It is sized to wire gauge 45, with a decimal diameter of 0.0820 inches, and features a titanium nitride (TiN) coating over a high speed steel (HSS) body. TiN coating increases surface hardness and reduces friction, extending edge life compared to uncoated HSS. The bit has a 118-degree standard point angle, a regular spiral flute, and a web-thinned, tapered web configuration that aids chip evacuation and reduces thrust at entry. Overall length is 2-1/8 inches with a 1-1/8 inch flute length. It cuts right-hand and runs with a straight-cylindrical shank.

This bit is suited for light-duty production and maintenance drilling tasks in machine shops, fabrication environments, and general trade work. The wire size 45 diameter places it in a precision small-bore range used by machinists, HVAC technicians, and electricians for pilot holes, tap drilling, and clearance holes. It is intended for use in standard drill presses, CNC machines, and hand-held power drills. The 0.0820 inch diameter falls within the 0.0500 to 0.1000 inch size range for this product family. Coolant-through is not supported on this bit.

Compatibility

Designed as a general purpose jobber length drill bit compatible with standard 3-jaw drill chucks accepting a 0.0820 inch straight-cylindrical shank, suitable for use in drill presses, CNC drilling machines, and portable power drills.

Installation Notes

Install in a properly sized drill chuck and tighten securely before use. Power down and de-energize any machine before changing bits. Use appropriate cutting fluid or lubrication when drilling metals to preserve coating life and bit geometry. Small-diameter bits are susceptible to breakage under side load — maintain perpendicular alignment to the workpiece throughout the drilling operation.
