Vargus 021-07630 Threading Insert 8 Tpi Acme 2G Solid Carbide

Product Description

The VARGUS 021-07630 is a solid carbide laydown threading insert designed for cutting external ACME 2G threads at 8 threads per inch. Built in the 3ER insert style with a 3/8 inch inscribed circle and a thickness of 0.1417 inches (3.60 mm), this insert is manufactured to the VTX grade and carries a TiAlN PVD coating for improved wear resistance and thermal stability. The 29-degree included angle is geometry-specific to ACME thread form requirements. Right-hand cutting orientation is standard. Machinists and toolroom technicians running threading operations on lathes or CNC turning centers are the primary users.

This insert is suited for external ACME 2G threading applications across industrial, mechanical, and production machining environments. ACME threads are commonly found on lead screws, power transmission components, vises, and actuator assemblies. The 8 TPI pitch targets medium-to-coarse thread profiles typical in those applications. The PVD TiAlN coating makes this insert a practical choice for threading steel, alloy steel, and similar ferrous materials where surface temperatures and abrasive wear are concerns.

Key Features

• Solid carbide construction with VTX manufacturer grade for consistent cutting performance
• TiAlN coating applied via PVD process for thermal resistance and extended tool life
• External ACME 2G thread form at 8 TPI with 29-degree included angle
• 3ER insert style with 3/8 inch inscribed circle for standard toolholder compatibility
• Right-hand cutting orientation for standard lathe and CNC turning setups
• Thickness of 0.1417 inches (3.60 mm) for precise seating in laydown insert pockets

Compatibility

Designed for use in laydown threading toolholders that accept the 3ER insert style with a 3/8 inch inscribed circle. Consult your toolholder manufacturer specifications to confirm pocket geometry and clamping compatibility before installation.

Installation Notes

Installation should be performed by a qualified machinist familiar with indexable threading insert toolholders. Ensure the machine spindle is fully stopped and the toolholder is secure before seating or replacing the insert. Verify the insert pocket is clean and free of chips or debris prior to clamping to ensure correct seating depth and thread form accuracy. Follow the toolholder manufacturer torque guidelines for the clamping screw.
