Hertel H05768429 Threading Insert 6 Tpi 3/8 Inch Ic

Product Description

The HERTEL H05768429 is a solid carbide laydown threading insert designed for internal Stub Acme thread cutting at 6 threads per inch (TPI). Carrying the HG330TR grade designation, this insert features a TiC/TiN multilayer coating that improves wear resistance and extends tool life during threaded-bore operations. The 3/8 inch inscribed circle (0.3750 inches) and 0.146 inch thickness conform to standard 16IR toolholder seating geometry. It is configured for right-hand cutting and fits standard laydown insert pockets used in CNC turning centers and manual lathes. Machinists and tool-room operators working in production or job-shop environments install this insert when cutting internal Stub Acme thread forms in ferrous and non-ferrous materials.

This insert is suited for internal threading operations on CNC lathes and turning centers where Stub Acme thread profiles are required. Stub Acme threads are commonly found in power-transmission applications such as linear actuators, lead screws, and valve stems. The 6 TPI pitch makes this insert appropriate for medium-to-coarse thread applications in those component types. It is a single-point threading insert sold individually, with a minimum order quantity of 10 units per purchase transaction.

Installation Notes

Installation is performed by machinists or toolroom technicians on CNC or manual turning equipment. Power down and lock out the machine before seating or replacing inserts. Use the appropriate torque wrench and insert screw specified by the toolholder manufacturer — do not overtighten, as this can fracture the carbide substrate. Verify insert seating and pocket cleanliness before initiating a threading pass.
