CNMG 120412 AH6235 indexable insert for turning — Tungaloy, PVD-coated carbide

A CNMG120412 AH6235 indexable insert engineered for external and internal turning, optimised for stainless steel and interrupted cutting conditions.

PVD-coated carbide grade AH6235
Suitable for stainless steel and interrupted cuts
ISO CNMG rhombic insert, 80° cutting angle
Double-sided chipbreaker, cylindrical hole fit

Higher productivity through wear-resistant coating and grade

The combination of a PVD-coated surface with a tougher carbide grade delivers extended tool life under challenging conditions. This insert is designed to maintain cutting-edge stability during cyclic loads and disrupted cuts, which leads to fewer insert changes and reduced machine downtime. The result is measurable efficiency in batch production and continuous turning tasks, supported by the optimised chip control of the integrated double-sided chipbreaker.

Consistent surface finish and process security in stainless machining

For operations on stainless steel, the tougher AH6235 grade minimises edge chipping and supports reliable metal removal even when interruption occurs. The rhombic geometry with an 80° approach angle balances shear control and strength, producing consistent workpiece surfaces and reducing the need for secondary finishing. This stability supports predictable throughput and easier process parameter tuning on the shop floor.

Compatibility and handling that simplify tool planning

As an ISO CNMG insert, the component fits a wide range of holders provided the form, relief angle, tolerance class, fastening and thickness match. The centrally located cylindrical hole ensures straightforward indexing and secure clamping, while the 4.76 mm plate thickness adds rigidity for heavier cuts. This compatibility reduces inventory complexity and makes it simpler to standardise tooling across multiple machines or production cells.

Cost-effectiveness through fewer interventions and predictable performance

By combining robust substrate properties with a wear-resistant coating, this insert reduces the frequency of tool swaps and unexpected stoppages. The predictable wear behaviour allows longer intervals between inspections and more consistent batch outputs, translating into lower operating costs and higher overall equipment effectiveness. The design supports a balance between durable performance and economical use for medium to high-volume turning applications.

FAQ

What materials is this insert best suited for?
The CNMG120412 AH6235 indexable insert is optimised for stainless steel and applications with interrupted cuts, leveraging the AH6235 grade and PVD coating for improved edge stability.

How does the chip control perform in interrupted cutting?
The double-sided chipbreaker on the CNMG insert provides reliable chip formation under interrupted conditions, reducing edge damage and helping to maintain consistent machining cycles.

Is this insert compatible with standard CNMG holders?
Yes; compatibility is determined by plate form, relief angle, tolerance class, fastening method, size and thickness — the ISO CNMG format ensures broad holder compatibility when dimensions match.

What benefits does the PVD coating provide?
The PVD-coated carbide grade AH6235 increases wear resistance and reduces the risk of chipping, thereby extending tool life and improving process reliability during stainless steel turning.
