Hertel 85703403 Jobber Drill Bit 9/64 Inch Hss 118 Degree

Product Description

The HERTEL 85703403 is a jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastic. Built from high speed steel with a bright uncoated finish, it delivers reliable performance across a wide range of shop and field applications. The bit features a 118-degree standard point angle with web thinning for easier penetration and reduced walking on entry. At 2-7/8 inches overall length with a 1-3/4 inch flute length, it fits standard drill chucks and drill presses without modification. The straight-cylindrical shank measures 9/64 inch in diameter, matching the bit diameter for secure chuck engagement. Machinists, fabricators, and maintenance technicians working in light industrial and trade settings will find this a dependable everyday cutting tool.

This bit is suited for general-purpose drilling tasks in residential and light commercial maintenance, fabrication shops, and field service work. The 9/64 inch diameter is commonly used for pilot holes, clearance holes, and tap drilling in ferrous and non-ferrous materials. The two-flute spiral design with a regular spiral type clears chips efficiently during through-hole drilling. It is sold individually but requires a minimum order quantity of 12 units, making it practical for stocking tool cribs or service van inventories.

Installation Notes

Secure the shank fully in a properly tightened drill chuck before operation. Use appropriate cutting fluid or coolant when drilling hardened or abrasive materials to extend bit life. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point is damaged. Follow applicable shop safety procedures and wear appropriate eye protection during drilling operations.
