Hertel H05767579 Threading Insert 16 Tpi Acme Solid Carbide

Product Description

The HERTEL H05767579 is a laydown threading insert designed for internal Acme thread cutting at 16 threads per inch. Manufactured from solid carbide with a TiC/TiN coating, this insert provides wear resistance and thermal protection during threading operations. It carries an insert style designation of 16IR, a 3/8-inch inscribed circle, and a thickness of 0.146 inches. The right-hand cutting orientation and zero-degree relief angle make it suited for Acme thread form applications on lathes and threading machines. Machinists, toolroom operators, and CNC turning professionals install this insert in compatible laydown threading toolholders.

This insert is used in metal cutting operations requiring precise internal Acme thread profiles. The Acme thread form is common in power-transmission components such as lead screws, vises, and linear actuators. At 16 TPI, this insert produces coarser-pitch Acme threads found in medium-duty mechanical assemblies. It is appropriate for use in both production turning environments and job-shop applications where Acme threading capability is needed on a lathe or turning center equipped with a matching 16IR laydown toolholder.

Key Features

• Solid carbide substrate with TiC/TiN coating for extended tool life in threading applications
• 16 TPI cutting geometry ground to Acme thread standard
• Right-hand internal thread orientation for standard Acme threading operations
• 3/8-inch inscribed circle fits 16IR-series laydown threading toolholders
• 0.146-inch insert thickness for secure, repeatable laydown seating
• Zero-degree relief angle consistent with Acme thread form geometry

Compatibility

Designed for use in 16IR-style laydown threading toolholders configured for internal Acme thread cutting. Confirm toolholder pocket geometry and insert seating requirements before installation.

Installation Notes

Installation is performed by machinists or CNC toolroom technicians. Power down and lock out the machine spindle before changing inserts. Use the correct torque wrench and clamping screw specified by the toolholder manufacturer to seat the insert without cracking the carbide substrate. Inspect the insert seating pocket for chips or debris before clamping, as contamination can cause insert rocking and poor thread form accuracy.
