CNMG 120404 AH6235 Tungaloy indexable turning insert – PVD-coated carbide, 80°

The CNMG 120404 AH6235 is an ISO-standard indexable turning insert engineered for external and internal turning, optimised for challenging stainless-steel applications and interrupted cutting conditions.

• ISO-standard geometry for holder compatibility
• PVD-coated carbide AH6235 for toughness
• Optimised for stainless steel and interrupted cuts
• Double-sided design with cylindrical hole for secure clamping

Consistent performance in stainless-steel machining

The combination of a PVD-coated surface and a tough AH6235 carbide grade delivers enhanced resistance to chipping and work-hardening when machining stainless steels. This results in steadier cutting forces, improved surface integrity and fewer unplanned tool changes. The design focuses on sustaining cutting edge integrity under intermittent engagement, which translates to longer uninterrupted production runs and lower process variability.

Secure clamping and straightforward machine integration

The CNMG geometry with 80° approach angle and a cylindrical hole allows secure, repeatable clamping in standard ISO external holders. The rhombic plate form and the double-sided configuration permit indexation of a fresh cutting edge without tool change, reducing machine downtime. Compatibility is ensured by standardised form, clearance angle and thickness, so the insert integrates smoothly into common turning tool systems.

Coating and substrate engineered for edge stability

A PVD-coated surface on a tough carbide substrate improves wear resistance while maintaining edge toughness. This balance reduces notch wear on reactive materials and helps control heat at the cutting zone, supporting consistent chip formation. The integrated double-sided chipbreaker is tailored for mixed and interrupted cuts, assisting with chip control and reducing the risk of built-up edge in sticky materials.

Practical selection and application guidance for production

Select a chipbreaker and grade that suit the workpiece and machining strategy: the AH6235 grade is recommended for demanding stainless steel tasks and applications with elevated breakout risk. Ensure the toolholder matches the insert’s ISO designation, thickness and hole style; secure clamping combined with correct cutting data yields repeatable surface finish and tool life. The insert forms part of a system: holder, clamping parts and spare screws should be checked for compatibility during set-up.
