Hertel H05767371 Threading Insert 10 Tpi 3/8 in Carbide

Product Description

The HERTEL H05767371 is a laydown threading insert designed for cutting external Acme threads on CNC and manual lathes. Built from solid carbide with a TiC/TiN coating, it delivers consistent thread form and extended tool life in ferrous and non-ferrous materials. The insert carries a 10 threads per inch (TPI) pitch, fits a 3/8 inch inscribed circle toolholder seat, and measures 0.146 inches thick. The HG630TR manufacturer grade is suited to a range of threading applications where dimensional accuracy and surface finish are priorities. This insert is installed by machinists and toolroom technicians on production and job-shop turning equipment.

This insert is used for right-hand external Acme thread turning operations, commonly found in power-screw and lead-screw production for industrial, agricultural, and mechanical equipment. The Acme thread standard is widely specified wherever a trapezoidal thread form is required for load transfer or linear motion. The laydown seating style provides positive indexing in compatible toolholders, making it appropriate for repeat-production threading passes on turned components.

Key Features

• Solid carbide substrate with TiC/TiN coating for wear resistance and extended edge life
• 10 TPI Acme external thread form for lead-screw and power-screw applications
• Right-hand cutting geometry for standard lathe threading operations
• 3/8 inch inscribed circle for compatibility with standard laydown threading toolholders
• 0.146 inch insert thickness for stable, positive seating in the toolholder pocket
• Zero relief angle geometry for use with toolholders that provide relief through holder design

Compatibility

Designed for use in standard laydown threading toolholders accepting a 16ER insert style with a 3/8 inch inscribed circle. Confirm toolholder insert-pocket specifications before installation.

Installation Notes

This insert is installed and indexed by machinists using manufacturer-specified torque on the insert clamping screw — consult the toolholder documentation for the correct value. Ensure the machine spindle is stopped and the toolholder is removed or secured before changing inserts. Inspect the toolholder pocket for chips or damage before seating the new insert. Dispose of worn carbide inserts in accordance with applicable facility waste and safety guidelines.
