Hertel H08695363 Threading Insert 20 Tpi 3/8 in Ic Un

Product Description

The HERTEL H08695363 is a laydown-style threading insert designed for right-hand internal UN thread cutting at 20 threads per inch. Built from solid carbide with a TiC/TiN finish, this insert delivers consistent thread form and wear resistance in demanding CNC turning and threading applications. The 3/8 inch inscribed circle and 0.146 inch thickness conform to the 16IR insert style geometry. The TiC/TiN coating improves surface hardness and reduces friction during thread cutting, extending tool life in ferrous and non-ferrous materials. This insert is specified by machinists and tooling technicians working with standard UN internal thread profiles.

This insert is suited for internal threading operations on lathes and turning centers where UN-standard thread forms are required. The right-hand cutting orientation and 20 TPI specification make it appropriate for common fastener thread profiles in manufacturing, maintenance, and repair machining. The 16IR insert style seats into compatible laydown threading toolholders. Sold individually, with a minimum order quantity of 10 units per order.

Key Features

• 3/8 inch inscribed circle with 0 degree relief angle for positive seating
• 0.146 inch thickness consistent with standard 16IR seat geometry

Compatibility

Designed as an OEM-style replacement or direct tooling insert for 16IR-style laydown threading toolholders used in internal UN thread cutting applications.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine powered down and the spindle locked before indexing or replacing inserts. Use the appropriate torque wrench and insert screw for the toolholder to avoid seat damage. Inspect the insert pocket and clamping screw for wear before seating a new insert. Verify thread form with a calibrated thread gauge after first-pass cuts.
