CNMG 120402 AH6225 Turning Insert – PVD-coated carbide, 0.2 mm radius (Tungaloy)

A CNMG120402 AH6225 insert for ISO-based turning applications, optimised for medium cutting conditions and reliable performance on stainless steels.

• ISO rhombic 80° geometry
• PVD-coated carbide grade AH6225
• 0.2 mm corner radius for versatility
• Double-sided insert with cylindrical hole

Stable edge for consistent stainless-steel turning

The PVD-coated carbide composition of this insert ensures a sharp yet robust cutting edge, particularly suited to machining stainless steels under variable conditions. The AH6225 grade combines wear resistance with controlled edge geometry, which reduces the risk of edge chipping and preserves surface finish over extended cuts. For shops seeking predictable tool life and repeatable results, the CNMG form delivers a balance between toughness and wear resistance while the 0.2 mm corner radius supports a wide range of turning tasks without compromising profile accuracy.

Simple system integration and predictable fit

Designed as an ISO-standardised insert, the rhombic CNMG form matches common clamping systems by shape, relief angle and thickness; compatibility is defined by form, relief, tolerance class, fastening, size and thickness. The insert’s cylindrical hole and standard dimensions make it a drop-in option for many external holders and boring bars, simplifying tool management. Using standardised components reduces setup time and minimises inventory complexity, enabling faster changeovers and lower organisational overhead in production environments.

Productivity through chip control and economy

The double-sided chipbreaker supports stable chip formation during external and internal turning, which contributes to smoother machining and reduced machine downtime. Because the insert can be indexed, two cutting edges are available per side, extending the effective lifetime and lowering cost per cutting edge. The combination of a resilient substrate and the AH6225 coating is optimised for medium cutting speeds common in stainless-steel operations, helping to maintain surface quality and process stability across batch runs.

Practical selection guidance for reliable results

When selecting an insert for a specific turning task, match the chipbreaker and grade to workpiece material, machining method and machine stability. For stainless steels under medium conditions, AH6225 is a universal choice offering a compromise between initial sharpness and edge protection. The CNMG geometry is particularly suitable for turning profiles and general external operations; for finishing passes the smaller corner radius supports finer surface quality while for heavier cuts consideration of larger radii and alternative grades is advised.
