Hertel 85707578 Jobber Drill Bit Wire 34 Hss Tin

Product Description

The HERTEL 85707578 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastic. Built from high speed steel (HSS) with a titanium nitride (TiN) coating, it delivers extended tool life compared to uncoated HSS by reducing friction and heat buildup at the cutting edge. The bit is wire gauge size 34, with a decimal diameter of 0.1110 inches and a 118-degree standard point angle. Overall length is 2-5/8 inches with a 1-1/2-inch flute length. The straight cylindrical shank seats in standard drill chucks. Machinists, tool-and-die techs, and maintenance mechanics are the primary users.

This bit is suited for light-to-medium duty drilling operations on the bench, in a drill press, or handheld. The regular spiral flute and tapered web configuration with web thinning support efficient chip evacuation and reduced thrust in softer metals and non-ferrous materials. At 0.1110 inches, it falls in the 0.1000 to 0.1500 inch decimal range, making it a common selection for tapping pilot holes, clearance holes, and precision work in maintenance and fabrication environments. Each package contains one bit, with a minimum order quantity of 12 units.

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard drill presses, CNC machines, and hand drills equipped with a chuck that accepts a 0.1110-inch straight cylindrical shank.

Installation Notes

Installation and use should be performed by machinists or qualified trade personnel familiar with rotating cutting tools. Secure the shank fully in the chuck and verify concentricity before operation. Always wear eye protection and ensure the workpiece is clamped before drilling. Do not exceed the recommended RPM for the bit diameter and material being drilled.
