Hertel H05768254 Threading Insert 14 Tpi Stub Acme Solid Carbide

Product Description

The HERTEL H05768254 is a laydown threading insert designed for internal Stub Acme thread cutting at 14 threads per inch (TPI). Built from solid carbide and finished with a TiC/TiN coating, this insert delivers the wear resistance and surface hardness that high-cycle threading operations demand. It carries the HG630TR manufacturer grade designation and features a 3/8 inch (0.375 inch) inscribed circle and a thickness of 0.146 inches. The right-hand cutting orientation and 16IR insert style make it a direct fit for compatible laydown-style toolholders. Machinists and CNC turning specialists working on Stub Acme thread profiles are the primary installers of this insert.

This insert is suited for internal threading operations where Stub Acme thread forms are required, such as lead screw applications, power transmission components, and valve stems. The solid carbide substrate with TiC/TiN finish performs across a range of workpiece materials including steel and cast iron. It is packaged individually and sold in a minimum order quantity of 10 units, making it appropriate for shop stock replenishment or dedicated threading operations that require consistent insert performance across multiple setups.

Installation Notes

Installation is performed by machinists or CNC lathe operators during tooling setup. Power down and lock out the machine before seating or replacing inserts. Use the appropriate torque wrench and insert key to secure the clamping screw without overtightening, which can fracture the carbide substrate. Inspect the insert seat and clamping pocket for debris or damage before installing a fresh insert.
