Consistent machining performance for stainless steels

The PVD-coated carbide grade AH6225 provides a balanced combination of wear resistance and edge sharpness, tailored for machining stainless steels in variable conditions. The coating stabilises the cutting edge at elevated temperatures, which reduces microchipping and extends tool life; this leads to fewer tool changes and improved process efficiency. For operations where repeatable surface finish and consistent cycle times matter, the combination of a controlled edge geometry and a dedicated coating delivers measurable productivity gains while maintaining part quality.

Mounting, compatibility and geometry explained

Compatibility with toolholders is governed by form, clearance angle, tolerance class, fastening, size and thickness. The rhombic VBMT outline with an inscribed circle of 16 mm and a plate thickness of 4.76 mm suits a wide range of ISO holders. The insert features a cylindrical hole with a single-sided countersink (40°–60°) for secure clamping and correct seat location. A 5° clearance angle and a 35° wedge geometry ensure predictable cutting forces, while the 0.2 mm corner radius provides a compromise between edge strength for interrupted cuts and the ability to achieve a fine surface finish. These geometric parameters simplify holder selection and process planning in industrial turning setups.

Chip control and selection advice for reliable results

The PS chipbreaker is matched to the grade and geometry to encourage stable chip formation when turning stainless steels, lowering the risk of built-up edge and improving surface consistency. In practice, select the chipbreaker and cutting parameters according to material condition and machine stability: a more rigid setup permits higher feeds and productivity, whereas less stable conditions favour lighter cuts and conservative parameters to protect the edge. For users seeking repeatable production, pairing the insert with an appropriately rated external holder and following standard coolant or dry-cutting practices will deliver the expected tool life and dimensional stability. Manufacturer grade and geometry choices reduce process variation and support predictable component output.

FAQ

What materials is this insert suited for? The VBMT160402-PS AH6225 insert is designed primarily for stainless steels, with the PVD-coated carbide composition engineered for medium machining and variable conditions.

How does the 0.2 mm corner radius affect performance? A 0.2 mm corner radius provides a compromise between edge strength and surface finish: it improves resistance to chipping under intermittent cuts while still enabling good surface quality when using appropriate feeds and speeds.

Which chipbreaker should be selected for stainless steels? The PS chipbreaker supplied with this designation is optimised for controlled chip formation in stainless steels; selection may be adjusted depending on workpiece stability and the desired surface finish.

Is the insert compatible with standard ISO holders? Compatibility depends on holder form, clearance angle, tolerance class, fastening and size; the insert follows ISO dimensions (VBMT 160402 series) and fits matching ISO-standard external holders.

What are the mounting features of the insert? The insert has a cylindrical hole with a single-sided countersink (40°–60°) to ensure secure clamping and correct seating in compatible holders.
