Consistent cutting performance for stainless steel

The PVD-coated AH6225 grade offers a balanced combination of wear resistance and edge stability that favours medium-duty turning operations in stainless steel. The PVD layer reduces adhesive wear and provides a uniform surface that supports repeatable cutting behaviour; this means fewer unexpected interruptions and more predictable tool change intervals. As an ISO-format cutting insert, it is produced to defined tolerances so that insert seating and repeatability in the toolholder are reliable, contributing directly to stable production runs and consistent part quality.

Geometry tuned for predictable chip control and surface finish

A 35° cutting lead angle combined with the rhombic VNMG form and a 1.2 mm corner radius produces a compromise between a sharp cutting edge and mechanical robustness. The geometry helps to control the engagement and direction of the chip, supporting smoother chip flow and reducing vibration in many turning scenarios. For machinists and production engineers, this translates into improved surface finish and reduced need for downstream rework, particularly when machining components with changing profiles or interrupted cuts.

Stable edge and economical productivity

The insert’s design emphasises a sharp edge that remains resilient across variable conditions. The PVD-coated carbide substrate sustains cutting-edge integrity under thermal and mechanical loads typical of stainless steel turning. Economically, the combination of edge life and consistent cutting behaviour lowers the total cost per part: fewer insert changes, reduced cycle-time variability and better utilisation of machine capacity. Where process reliability is crucial, the grade’s balance of sharpness and robustness supports productive, repeatable machining.

System compatibility and straightforward integration

Being ISO-standardised, the insert fits into established toolholder systems when matched by form, clearance, tolerance class, fastening method, size and thickness. The insert is double-sided and supplied with a cylindrical central hole, facilitating secure clamping and easy indexing. Key dimensions such as the 16 mm inscribed circle, 4.76 mm thickness and the specified clearance angle mean straightforward selection of compatible holders and clamping kits. When integrated correctly, the cutting system yields improved stability and predictable performance across batches.
