• Double-sided chipbreaker, cylindrical hole

Reliable cutting performance for stainless steel machining

The AH6225 grade combines a PVD finish with a wear-resistant carbide substrate to provide a sharp and stable cutting edge for turning applications. This composition supports consistent cutting behaviour when machining stainless steel, reducing the need for frequent edge changes during varied production runs. For operators less familiar with coatings: PVD (physical vapour deposition) creates a thin, hard layer that improves wear resistance and helps maintain edge geometry under thermal and mechanical stress, which translates into steadier component tolerances and fewer scrap parts.

Secure seating and repeatable tool engagement

Compatibility with standard toolholders is determined by the insert’s geometry and dimensions; the rhombic ISO-standard shape, cylindrical hole and a 4.76 mm thickness ensure dependable clamping. The plate’s 80° main cutting angle and 0° clearance contribute to a predictable cutting contact that is particularly useful in set-ups with limited rigidity. The modest 0.4 mm corner radius helps to balance edge strength and surface finish. Clear identification of these parameters simplifies holder selection and reduces set-up time, improving process repeatability and lowering the risk of vibration-related tool wear.

Operational economy through doubled edges and controlled chips

A double-sided chipbreaker and two usable cutting edges per face mean the insert offers an economical cost-per-edge compared with single-sided alternatives. The optimised chip geometry promotes stable chip formation, easing evacuation and reducing incidental tool interference, which in turn supports longer uninterrupted cycles and improved surface quality. Careful pairing of chipbreaker style and the AH6225 grade with machine stability and cutting data yields tangible gains in overall productivity and fewer unscheduled tool changes, contributing to lower production costs over time.

FAQ

What materials is this insert suitable for?
The CNMG090404 AH6225 insert is designed primarily for stainless steel; the AH6225 grade and PVD coating give robust performance across a range of alloyed steels commonly found in stainless-steel turning.

How does the insert secure to the holder?
The rhombic form with a cylindrical hole and ISO-standard geometry provides a repeatable seating and clamping mechanism; compatibility is defined by holder form, tolerance class and the insert’s dimensions.

Is the insert reversible to use multiple cutting edges?
Yes, the double-sided chipbreaker design offers multiple usable edges per index, which extends service intervals and improves cost efficiency.

Which features contribute to surface finish and tool life?
The combination of the AH6225 grade, PVD coating and a modest corner radius supports a stable cutting edge, while the chipbreaker promotes controlled chips—together these factors enhance surface finish and extend effective tool life.

Can this insert be used for internal turning as well as external turning?
The ISO-standard CNMG geometry is suitable for both external and many internal turning tasks, provided the holder and overhang meet the necessary rigidity and clearance requirements.
