Hertel H05768064 Threading Insert 8 Tpi 3/8 in Stub Acme

Product Description

The HERTEL H05768064 is a laydown threading insert designed for right-hand external Stub Acme thread cutting at 8 threads per inch. Manufactured from solid carbide with a TiC/TiN coating, this insert delivers wear resistance and heat control suited for demanding threading operations on lathes and turning centers. It features a 3/8-inch inscribed circle and a 0.146-inch thickness with a 0 degree relief angle, conforming to the 16ER insert style. Licensed machinists and CNC operators working with Stub Acme thread forms will find this insert geometry built to spec for consistent thread profile accuracy.

This insert is intended for external threading applications where the Stub Acme thread standard is required, such as lead screws, linear actuators, and power-transmission components. The right-hand cutting orientation makes it suitable for conventional lathe setups turning standard right-hand threaded workpieces. It is used in production and job-shop environments where solid carbide tooling is selected for extended tool life over high-speed steel alternatives. Sold individually with a minimum order quantity of 10 units.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the toolholder is secure before seating or replacing the insert. Use the appropriate torx or clamp screw driver specified by the toolholder manufacturer to torque the insert clamp — do not overtighten by feel alone. Verify insert orientation for right-hand cutting direction before resuming operation.
