Hertel H05767702 Threading Insert 10 Tpi 3/8 in Ic Acme

Product Description

The HERTEL H05767702 is a laydown-style threading insert designed for internal Acme thread cutting applications. Manufactured from solid carbide and finished with a TiC/TiN multilayer coating, this insert delivers consistent thread form geometry and extended tool life in demanding turning operations. It carries an insert style designation of 16IR, operates at 10 threads per inch (TPI), and features a 3/8-inch inscribed circle (IC) diameter with a thickness of 0.146 inches. The HG330TR grade is suited for threading ferrous and non-ferrous materials where coating-enhanced wear resistance is required. Machinists and toolroom technicians working on CNC lathes or manual turning centers are the primary installers.

This insert is used in right-hand internal threading operations producing Acme thread profiles. Acme threads are standard in power-transmission components such as lead screws, jacks, and linear actuators. The 16IR style mounts in compatible laydown threading toolholders designed for that insert geometry. This insert is appropriate for both production and repair threading work in job shop, manufacturing, and maintenance-machining environments.

Key Features

• Solid carbide substrate for rigidity and wear resistance in threading operations
• TiC/TiN multilayer coating enhances surface hardness and reduces built-up edge
• 10 TPI Acme thread form for right-hand internal thread cutting
• 3/8-inch inscribed circle ensures compatibility with 16IR-style laydown toolholders
• 0.146-inch insert thickness provides stable seating in the pocket
• Relief angle of 0 degrees suits laydown-style holder geometry

Compatibility

Designed for use in 16IR-style laydown threading toolholders configured for internal Acme thread inserts. Verify toolholder pocket geometry and clamping configuration against the 16IR insert style before installation.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before seating or indexing the insert. Use the appropriate torque wrench and insert screw specified by the toolholder manufacturer — do not overtighten, as solid carbide inserts are brittle and can crack under excess clamping force. Confirm thread form and pitch with a thread gauge on the first part before committing to a production run.
