Hertel H05768452 Threading Insert 5 Tpi 1/2 in Ic Stub Acme

Product Description

The HERTEL H05768452 is a laydown-style threading insert designed for internal Stub Acme thread cutting applications. Built from solid carbide and coated with a TiC/TiN multilayer finish, this insert delivers consistent thread form geometry and extended cutting life in ferrous and alloy materials. It carries an insert style designation of 22IR, a manufacturer grade of HG630TR, and is configured for right-hand cutting. With a thread pitch of 5 TPI and a 1/2 inch inscribed circle, it fits standard toolholders sized for that IC class. Machinists and CNC operators working in job shop or production environments rely on this geometry for precise Stub Acme internal thread forms.

This insert is suited for internal threading operations on lathes and turning centers where Stub Acme thread profiles are required. Stub Acme threads are commonly found in lead screw assemblies, linear actuators, and power transmission components. The right-hand orientation and 5 TPI pitch make this insert appropriate for medium-pitch internal thread cutting on steel, cast iron, and similar workpiece materials. It is sold individually, with a minimum order quantity of 10 pieces per purchase.

Installation Notes

Installation is performed by qualified machinists or CNC technicians. The machine spindle must be stopped and all motion arrested before indexing or replacing the insert. Seat the insert fully against the toolholder pocket and secure the clamping screw to the toolholder manufacturer specification. Inspect the insert seating and thread form on a test pass before committing to a production run.
