Hertel H05767454 Threading Insert 6 Tpi 1/2 Inch Ic Carbide

Product Description

The HERTEL H05767454 is a solid carbide laydown threading insert designed for right-hand external Acme thread cutting at 6 threads per inch (TPI). It carries a TiC/TiN multilayer coating that improves surface hardness and wear resistance during threading operations on ferrous and non-ferrous materials. The insert style designation is 22ER, with a 1/2-inch (0.5000-inch) inscribed circle and a thickness of 0.187 inches. It is used by machinists and CNC lathe operators who require consistent, repeatable thread form geometry on external Acme profiles. Manufactured under the HG630TR grade, the substrate and coating combination supports moderate-to-high cutting speeds.

This insert is suited for external Acme thread turning operations on lathes and turning centers in production and job-shop environments. Acme threads are commonly found in lead screws, power transmission components, and linear actuator assemblies. The right-hand orientation makes this insert compatible with standard right-hand threading tool holders accepting the 22ER insert style. It is appropriate for both light finishing and general-purpose threading passes where Acme thread form accuracy is required.

Key Features

• Solid carbide substrate with TiC/TiN coating for extended tool life
• 22ER insert style for use with standard external threading tool holders
• 6 TPI Acme thread form — right-hand external orientation
• 1/2-inch inscribed circle (0.5000 inches) for secure seating in holder pocket
• 0.187-inch insert thickness provides rigidity during threading cuts
• 1-degree relief angle suited for laydown-style insert geometry

Compatibility

Designed as a direct-fit replacement for 22ER-style external threading tool holders accepting a 1/2-inch inscribed circle laydown insert in right-hand configuration.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. The machine spindle must be stopped and the tool post secured before seating or replacing the insert. Use the appropriate torx or hex wrench to clamp the insert per the tool holder manufacturer specification — do not overtighten the clamping screw. Confirm insert seating and thread form alignment with a thread gauge before resuming cutting operations.
