Hertel H05767975 Threading Insert 12 Tpi Stub Acme Carbide

Product Description

The HERTEL H05767975 is a laydown threading insert designed for cutting external Stub Acme threads on a lathe or CNC turning center. Built from solid carbide with a TiC/TiN multilayer coating, it delivers wear resistance and thermal stability during threading operations. The insert follows a 16ER style geometry with a right-hand cutting orientation, a 12 threads-per-inch (TPI) pitch, and a 3/8-inch inscribed circle. At 0.146 inches thick with a zero-degree relief angle, this is a precision ground insert intended for machinists and toolroom professionals working on threaded components in steel and similar workpiece materials.

This insert is suited for external threading applications where Stub Acme thread forms are required, such as lead screws, power transmission components, and linear motion assemblies. The 12 TPI pitch and 16ER laydown profile make it compatible with standard 16ER-style toolholders. It is appropriate for both production turning environments and job shop work where repeatable thread form accuracy is critical. Each insert is sold individually, with a minimum order quantity of 10 units per order.

Key Features

• Solid carbide substrate for rigidity and long tool life in threading applications
• TiC/TiN multilayer coating improves surface hardness and reduces built-up edge
• Right-hand external cut in the Stub Acme thread standard at 12 TPI
• 16ER insert style fits standard 16ER-style laydown threading toolholders
• Zero-degree relief angle geometry consistent with laydown insert seating
• 3/8-inch inscribed circle and 0.146-inch thickness for precise toolholder fit

Compatibility

Designed for use in standard 16ER-style laydown threading toolholders configured for external threading operations. Confirm toolholder seat geometry and insert pocket dimensions before installation.

Installation Notes

Threading inserts of this type are installed and replaced by machinists or toolroom technicians on CNC or manual lathes. Power down and lock out the machine before changing inserts. Use the correct torque wrench and insert screw specified by the toolholder manufacturer to seat the insert properly. Do not exceed the recommended depth of cut or feed rate for the insert grade, and inspect the insert for chipping or wear before each use.
