CNMG 120408 AH120 Tungaloy turning insert — PVD‑coated carbide, 80° geometry

The CNMG120408 AH120 Tungaloy insert is an ISO‑standard rhombic, double‑sided turning insert designed for dependable external and internal machining in ISO tool systems.

• ISO rhombic insert, 80° cutting geometry
• PVD‑coated carbide AH120 for wear resistance
• 0.8 mm corner radius for sharp edge control
• Double‑sided chipbreaker, with cylindrical hole

Consistent cutting stability for reliable turning results

The rhombic 80° geometry combined with a 0.8 mm corner radius provides a balance between a robust cutting edge and fine surface control, making the insert suitable for both roughing and light finishing passes. The double‑sided design doubles indexable life, reducing tool changes and supporting a steady production rhythm. As an ISO‑compliant insert, it integrates into standard toolholder systems where form, clearance and tolerance class determine compatibility, helping to maintain cycle times and reduce downtime.

Durable grade and coating for extended tool life

The AH120 grade is a PVD‑coated carbide formulated for wear and chipping resistance under typical turning conditions. The PVD layer increases hardness and heat resistance at the edge, which translates into improved tool life and more consistent part quality over longer runs. For applications where a sharp cutting edge and process reliability are required, this grade provides predictable performance and reduced frequency of insert replacement, contributing to lower tooling costs per component.

Quick integration and practical handling in the tooling system

ISO designation and standard dimensions simplify selection and changeover: the insert is a rhombic CNMG120408 with a cylindrical locating hole, 4.76 mm thickness and 12 mm inscribed size. This geometry permits straightforward clamping in appropriate external holders or boring bars together with a shim and clamp set; spare screws are included in typical system assemblies. The combination of ISO compatibility, a secure mounting interface and a proven chipbreaker geometry supports repeatable set‑ups and easier stock management for production shops.
