Hertel 2386704 Screw Machine Drill Bit 7/64 in Hss Tin

Product Description

The HERTEL 2386704 is a screw machine length drill bit designed for high-speed drilling in metal fabrication, maintenance, and production environments. Built from high-speed steel with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction during repeated use. The 135-degree split point minimizes walking on entry and reduces the thrust force needed to start a hole. At 1-13/16 inches overall length, this stub-length bit fits tight spaces where a jobber-length bit cannot reach. Licensed HVAC techs, plumbers, electricians, and general tradespeople keep these on hand for sheet metal work, panel drilling, and fixture installation.

This bit is suited for right-hand drilling in ferrous and non-ferrous metals, plastics, and composite materials. The straight-cylindrical shank fits standard 3-jaw drill chucks on corded drills, cordless drills, and drill presses. The shorter overall length provides greater rigidity than jobber-length bits, making it a practical choice for production drilling, repetitive hole patterns, and applications where chatter or deflection is a concern. It is sold individually and appropriate for both shop and field use.

Key Features

• TiN coating extends tool life and reduces heat buildup during drilling
• 135-degree split point starts on contact and reduces axial thrust
• Web-thinned, parallel-web construction improves chip evacuation
• Screw machine (stub) length increases rigidity and reduces deflection in tight spaces
• Heavy-duty drill bit grade rated for production and repetitive use
• Straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a direct-fit replacement screw machine drill bit for any standard 3-jaw drill chuck accepting a straight-cylindrical shank in the 0.1000 to 0.1500 decimal inch size range.

Installation Notes

This bit is installed and used by any trade professional operating a hand drill or drill press. Secure the straight shank fully in the chuck before operation and verify chuck tightness. Always wear appropriate eye protection when drilling. For best results in metal, use cutting fluid to reduce heat and extend bit life.
