Hertel 85704575 Jobber Drill Bit 23/64 Inch Hss Tin Coated

Product Description

The HERTEL 85704575 is a jobber-length twist drill bit designed for general-purpose hole-making in metal, wood, and plastic. Built from high speed steel with a titanium nitride (TiN) coating, it delivers improved surface hardness and extended tool life compared to uncoated HSS bits. The bit measures 23/64 inch in diameter (0.3594 inch decimal equivalent) with an overall length of 4-7/8 inches and a flute length of 3-1/2 inches. A standard 118-degree point angle and web-thinned, tapered web geometry reduce entry force and improve chip evacuation at the start of the cut. It carries a straight-cylindrical shank sized at 23/64 inch for use in standard drill chucks.

This bit is suited for production and maintenance drilling in light industrial, commercial, and trade settings. HVAC technicians, plumbers, electricians, and sheet metal workers will find it useful for drilling clearance holes, anchor pilot holes, and conduit entry points in ferrous and non-ferrous materials. The jobber-length format offers a balance of reach and rigidity that makes it practical across a range of hand-held and bench-mounted drilling operations.

Installation Notes

This bit is installed by a machinist, maintenance technician, or trade professional using a standard keyed or keyless drill chuck. Secure the shank fully in the chuck before operation and verify the bit runs true with no visible wobble. Always wear appropriate eye protection and secure the workpiece before drilling. Follow applicable workplace safety codes and tool manufacturer guidelines for feed rate and speed selection based on the material being drilled.
