Hertel H05767827 Threading Insert 5 Tpi 1/2 in Ic Acme

Product Description

The HERTEL H05767827 is a laydown-style threading insert designed for internal Acme thread cutting operations. Built from solid carbide with a TiC/TiN coating, this insert delivers wear resistance and heat tolerance suited to production threading environments. It carries an insert style designation of 22IR and manufacturer grade HG330TR. With a 1/2 inch inscribed circle and a thickness of 0.187 inches, it fits standard laydown threading toolholders configured for right-hand internal threading. Machinists and toolroom professionals use this insert for cutting Acme thread forms at 5 threads per inch on CNC lathes and manual turning centers.

This insert is appropriate for internal Acme threading applications in industrial machining, maintenance repair, and production environments. The Acme thread form is common in lead screw assemblies, linear actuators, vises, and power transmission components. The right-hand cutting geometry and 5 TPI pitch make it a direct selection for threading operations producing standard Acme profiles in those bore configurations. The TiC/TiN finish supports use across a range of ferrous and non-ferrous workpiece materials at moderate to high cutting speeds.

Key Features

• Solid carbide substrate with TiC/TiN coating for extended tool life and thermal resistance
• 22IR insert style in laydown configuration for compatibility with standard 22IR toolholders
• HG330TR manufacturer grade optimized for Acme thread cutting
• Right-hand cutting orientation for internal threading operations
• 5 threads per inch pitch matched to standard Acme thread specifications
• 1/2 inch inscribed circle and 0.187 inch thickness for positive seating in compatible pockets

Compatibility

Designed for use in 22IR-style laydown threading toolholders configured for internal Acme thread cutting at 5 TPI. Confirm toolholder insert pocket geometry and seating dimensions before installation.

Installation Notes

Threading inserts should be installed by qualified machinists familiar with lathe tooling and insert indexing procedures. Ensure the machine spindle is fully stopped and the toolholder is clear of the workpiece before seating or replacing the insert. Use the appropriate torque wrench and clamping hardware specified by the toolholder manufacturer — do not over-tighten the clamping screw. Inspect the insert pocket for chips or debris before seating to ensure proper contact and accurate thread profile.
