Hertel 75968057 Threaded Shank Drill Bit 5/32 in Hss

Product Description

The HERTEL 75968057 is a threaded shank drill bit designed for precision drilling in low-tensile strength materials. Built from high speed steel (HSS) with an oxide finish, it delivers reliable performance in repetitive drilling applications. The 135-degree split point reduces walking at entry and requires less feed pressure than conventional point geometries. With a 1/4-28 threaded hex shank, this bit is engineered for quick-change drill drivers and torque-sensitive tool holders commonly used in aerospace and sheet metal assembly environments. At 0.2 pounds, it is lightweight and easy to handle on the job.

This drill bit is suited for use in production and maintenance settings where controlled, repeatable hole placement is critical. The 5/32-inch diameter and 2.125-inch overall length (OAL) make it appropriate for light structural and sheet material work. The spiral flute configuration with a 1.125-inch flute length provides efficient chip evacuation during through-hole drilling in softer metals, plastics, and similar low-tensile materials. It is typically installed by machinists, aerospace maintenance technicians, and sheet metal fabricators.

Key Features

• 135-degree split point reduces walking and lowers required feed pressure
• 1/4-28 threaded hex shank for use with quick-change tool systems
• High speed steel construction with oxide coating for wear resistance
• Web-thinned, tapered web design improves cutting efficiency
• Right-hand cutting direction with regular spiral flutes for standard drilling operations
• Meets NAS 965 specification for threaded shank drill bits

Compatibility

Designed as an OEM-style replacement or production-use drill bit compatible with 1/4-28 threaded quick-change drill drivers and holders used in light manufacturing and maintenance applications.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with quick-change tooling systems. Ensure the drill driver or holder is fully de-energized and secured before inserting or removing the bit. Thread engagement should be firm and fully seated before operation. Always use appropriate eye protection and chip guards when drilling metals or plastics.
