Hertel H05767942 Threading Insert 14 Tpi Stub Acme

Product Description

The HERTEL H05767942 is a laydown threading insert designed for cutting external Stub Acme threads on a lathe or CNC turning center. Built from solid carbide with a TiC/TiN coating, it delivers consistent thread form and extended tool life on ferrous and non-ferrous workpiece materials. The insert uses the 16ER style seat geometry with a right-hand cutting orientation and produces threads at 14 TPI. With a 3/8 inch inscribed circle and a thickness of 0.146 inches, it seats securely in compatible 16ER toolholders. Installation is performed by machinists and CNC operators in production and job-shop environments.

This insert is suited for single-point threading operations on external Stub Acme thread forms, a profile commonly found in power-transmission components, actuators, and mechanical feed screws. The right-hand orientation makes it appropriate for standard right-hand thread cutting passes. It is sold individually but carries a minimum order quantity of 10 units, making it appropriate for toolcrib stocking and production-run replenishment.

Key Features

• Solid carbide substrate for wear resistance and dimensional stability under interrupted cuts
• TiC/TiN multilayer coating reduces friction and extends edge life
• 16ER insert style with 3/8 inch inscribed circle fits standard 16ER toolholders
• 14 TPI Stub Acme thread form for power-transmission and linear-motion applications
• Right-hand external cut orientation for conventional threading passes
• 0 degree relief angle laydown geometry for rigid seating in the pocket

Compatibility

Designed as an OEM-style replacement threading insert for lathes and CNC turning centers equipped with 16ER-style external threading toolholders accepting a 3/8 inch inscribed circle insert.

Installation Notes

Threading inserts are seated and clamped by a qualified machinist or CNC operator following the toolholder manufacturer torque and clamping procedures. Power down and lock out the spindle drive before changing inserts. Inspect the insert pocket for chips, burrs, or wear before seating a new insert, as pocket damage will affect thread-form accuracy. Follow your shop's tool-change and part-program verification procedures before taking a first threading pass.
