Hertel 85703544 Jobber Drill Bit 23/64 in Hss

Product Description

The HERTEL 85703544 is a jobber-length twist drill bit designed for general-purpose hole-making in metal, wood, and similar materials. Built from high speed steel with a bright uncoated finish, this bit delivers consistent performance across a wide range of drilling applications. It measures 23/64 inches (0.3594 inches decimal) in diameter with a standard 118-degree point angle and a right-hand spiral flute configuration. The straight-cylindrical shank seats securely in standard three-jaw chucks. With an overall length of 4-7/8 inches and a 3-1/2 inch flute length, it handles typical through-hole and blind-hole work on the bench, in the field, or on the shop floor.

This bit fits general fabrication, maintenance, and installation tasks common to HVAC, plumbing, electrical, and light industrial work. The two-flute spiral design evacuates chips efficiently, reducing heat buildup during moderate-speed drilling. The web-thinned, tapered web construction reduces the thrust force required to start and advance the cut, making it a practical choice for hand-drill or drill-press use when working with ferrous and non-ferrous stock, conduit strut, sheet metal brackets, and similar trade materials.

Key Features

• High speed steel construction for durability across general-purpose drilling tasks
• 118-degree standard point angle for versatile use in metal and other common materials
• Web-thinned tapered web reduces required thrust and improves hole starting accuracy
• Right-hand, two-flute spiral design promotes efficient chip evacuation
• Straight-cylindrical shank fits standard three-jaw chucks without adapters
• Bright uncoated finish suited for dry drilling and light cutting fluid use

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with standard three-jaw chucks and drill presses accepting a 23/64-inch straight-cylindrical shank.

Installation Notes

Install and remove this bit only when the drill or drill press is fully powered down and the chuck key is clear of the chuck. Secure the workpiece with a vise or clamp before drilling to prevent movement. A center punch mark at the hole location helps seat the bit point and reduces walking on hard surfaces. Use cutting fluid on ferrous metals to extend bit life and improve hole finish.
