Hertel 2385854 Screw Machine Drill Bit 9/64 Inch Hss

Product Description

The HERTEL 2385854 is a screw machine length drill bit designed for high-production drilling in metal fabrication, machining, and general mechanical work. Built from high-speed steel with an oxide finish, it measures 9/64 inch (0.1406 inch decimal) in diameter with an overall length of 1-15/16 inches and a flute length of 15/16 inch. The 135-degree split point reduces walking on entry and lowers the thrust needed to start a hole. The shorter screw machine length body provides added rigidity compared to jobber-length bits, making it well-suited for drill press and CNC work in tight setups. Licensed machinists, tool and die technicians, and mechanical contractors are the typical users.

This bit is appropriate for drilling into steel, aluminum, cast iron, and similar metals in residential and commercial maintenance, light manufacturing, and trade shop environments. The right-hand spiral flute with a parallel web configuration and web-thinned point improves chip evacuation and cutting efficiency in short-hole applications. It fits standard drill chucks accepting straight-cylindrical shanks and is sold individually, with a minimum order quantity of 12 units.

Key Features

• 135-degree split point reduces drill walking and lowers entry thrust
• High-speed steel construction rated for heavy-duty drilling applications
• Oxide coating improves wear resistance and reduces friction during cutting
• Screw machine length body provides greater rigidity than jobber-length bits
• Web-thinned, parallel web configuration promotes efficient chip clearance
• Right-hand spiral flute compatible with standard drill chucks

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for any drill press, hand drill, or CNC spindle accepting a straight-cylindrical shank in the 9/64 inch diameter range.

Installation Notes

This bit is installed and used by machinists, maintenance mechanics, and trade professionals working with metal substrates. Secure the straight-cylindrical shank fully in the chuck and verify chuck key tightening before operation. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend tool life and maintain hole quality. Inspect the cutting edge for wear or chipping before each use and replace bits that show signs of dulling to avoid workpiece damage.
