Hertel H05767652 Laydown Threading Insert 12 Tpi

Product Description

The HERTEL H05767652 is a solid carbide laydown threading insert designed for right-hand internal Acme thread cutting at 12 threads per inch. Built to insert style 16IR, this insert carries a TiC/TiN coating that improves wear resistance and extends cutting life in demanding threading operations. With a 3/8-inch inscribed circle and a thickness of 0.146 inches, the insert seats positively in compatible 16IR toolholders. It is intended for use by machinists and toolroom professionals on CNC lathes, turret lathes, and manual threading machines where precise Acme thread form control is required.

This insert is suited for internal Acme thread applications in production and job-shop environments. The Acme thread form is commonly found in lead screws, linear actuators, vises, and power transmission components. The right-hand cutting geometry means it is used on standard right-hand threaded bores. Manufacturer grade HG630TR indicates the carbide substrate and coating combination is optimized for steel and general-purpose threading at moderate cutting parameters. A relief angle of 0 degrees is consistent with laydown-style insert geometry.

Key Features

• Solid carbide substrate for rigidity and wear resistance in threading operations
• TiC/TiN coating extends tool life and reduces built-up edge
• 12 TPI Acme thread form for lead screw and power transmission applications
• Right-hand internal cut geometry in 16IR insert style
• 3/8-inch inscribed circle with 0 degree relief angle for positive laydown seating
• Manufacturer grade HG630TR for general-purpose threading in steel

Compatibility

Designed as an OEM-style replacement or standard supply insert for 16IR-style internal threading toolholders used in right-hand Acme thread applications.

Installation Notes

Indexable threading inserts should be installed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before changing inserts. Seat the insert firmly and evenly in the toolholder pocket and tighten the clamping screw to the toolholder manufacturer specification. Verify thread form and pitch with a thread gauge before running production parts.
