CNMG120408 AH6235 ISO turning insert, 80° rhombic — Tungaloy

The CNMG120408 AH6235 is an ISO-design turning insert designed for external and internal turning, optimised for stainless steel and interrupted cutting conditions.

• PVD-coated carbide grade AH6235
• 80° rhombic geometry for versatile turning
• Double-sided insert with cylindrical hole
• Suited to stainless steel and interrupted cuts

Stable cutting and longer tool life for demanding stainless steel work

The AH6235 grade is a PVD-coated carbide designed to improve resistance against built-up edge and chipping during interrupted or unstable cuts. With a combination of a tougher substrate and a hard, wear-resistant coating, the insert offers improved durability in applications where surface quality and predictable tool life are critical. This leads to fewer insert changes, reduced downtime and a more economical production flow when machining stainless steel and similar alloys.

Geometry and chip control that support process reliability

The 80° rhombic shape provides a favourable balance between cutting-edge strength and access to the component, making it suitable for a wide range of turning tasks. The insert’s double-sided chipbreaker promotes consistent chip formation and evacuation, which reduces the risk of chip entanglement and protects the cutting edge from excessive thermal and mechanical loads. Compatibility with the toolholder is determined by form, relief angle, tolerance class, clamping method, size and thickness, ensuring the insert can be integrated into existing tool systems with predictable results.

Practical process guidance and material application

For typical turning operations, select a holder that matches the ISO geometry and provides secure clamping for the rhombic insert with a cylindrical hole. The AH6235 grade performs particularly well in interrupted cuts and where the workpiece material tends to work-harden, such as stainless steel; the tougher substrate reduces edge failure. The ISO designation and standard dimensions simplify inventory management and replacement planning, supporting consistent machining outcomes across batches and shifts.
