Hertel H05767413 Threading Insert 8 Tpi 3/8 in Solid Carbide

Product Description

The HERTEL H05767413 is a solid carbide laydown threading insert designed for right-hand external Acme thread cutting at 8 threads per inch. It carries a TiC/TiN multilayer coating that improves wear resistance and extends edge life on demanding threading applications. With a 3/8 inch (0.3750 inch decimal) inscribed circle and a thickness of 0.1460 inches, this insert fits standard laydown-style threading toolholders in the 16ER style. It is intended for use by machinists and CNC lathe operators working in production or job-shop environments where Acme thread profiles are required on external workpiece diameters.

This insert is suited to threading operations on lathes and turning centers producing external Acme threads at 8 TPI. Acme threads are common in lead screws, power transmission components, and linear actuator applications. The solid carbide substrate handles the interrupted and continuous cut conditions typical in these applications. The 16ER insert style is a widely recognized laydown geometry used in a range of standard threading toolholder bodies. Installation requires a compatible 16ER-style toolholder.

Key Features

• Solid carbide substrate for rigidity and wear resistance in threading operations
• TiC/TiN multilayer coating for extended tool life and reduced built-up edge
• Right-hand external Acme thread profile at 8 TPI
• 3/8 inch inscribed circle (0.3750 inch decimal) in the 16ER laydown style
• 0.1460 inch insert thickness with 0-degree relief angle for laydown toolholder compatibility
• Manufacturer grade HG630TR suited to steel and general-purpose threading materials

Compatibility

Designed as a direct-fit replacement for standard 16ER-style laydown threading toolholders requiring an external Acme thread insert at 8 TPI. Consult your toolholder manufacturer specifications to confirm 16ER insert seat compatibility before installation.

Installation Notes

This insert is installed by a machinist or CNC tooling technician. The lathe or turning center must be powered down and the spindle locked before changing inserts. Use the correct torque wrench and insert screw specified by the toolholder manufacturer to seat the insert securely without over-torquing the clamping screw. Inspect the insert seat and clamping components for debris or damage before seating a new insert.
