CPMT09T304 AH6225 indexable turning insert by Tungaloy — PVD‑coated carbide for stainless steel turning

CPMT09T304 AH6225 is an ISO‑standard indexable insert optimised for turning applications, offering a balanced combination of edge sharpness and stability for medium machining of rostfreier Stahl

• PVD‑coated carbide for rostfreier Stahl
• ISO‑standard rhombic insert, 80° approach
• Sharp and stable cutting edge for medium cuts
• Cylindrical hole with countersink for secure clamping

Consistent surface quality and reliable cutting performance

The combination of a PVD‑coated substrate and the AH6225 grade results in a wear‑resistant cutting edge that maintains form under variable conditions. For machining rostfreier Stahl, a sharp yet stable edge reduces built‑up edge and improves surface finish, while the chosen carbide composition supports moderate cutting speeds without premature flank wear. This balance translates into fewer insert changes and predictable part quality, which is especially valuable in batch production and mixed‑material runs.

Fast, repeatable tool set‑up thanks to ISO conformity

Manufactured to ISO dimensions and a rhombic geometry, the insert guarantees compatibility with standard holders when form, clearance angle, tolerance class, fastening method, size and thickness match. The 80° approach angle and the 11° clearance are designed for stable seating and reliable chip flow. The insert’s cylindrical mounting hole with a single‑sided countersink (40°–60°) ensures secure clamping and accurate indexation, accelerating tool changes and reducing setup variability on the shop floor.

Lower process risk and improved productivity

The cutting grade and coating of this indexable plate support stable chip formation and good wear resistance under typical turning conditions. Selecting the appropriate single‑sided chipbreaker and grade for the workpiece material and machining stability minimises the risk of chatter and tool failure. As a result, machining cycles become more consistent, throughput increases and downstream finishing effort is often reduced, yielding a measurable productivity gain over time.

Practical guidance for turning operations and system composition

Suitable for both external and internal turning, the insert forms part of a system that includes a matching external holder or boring bar, a shim/clamping set and replacement screws. When replacing an insert, check that the holder geometry and tolerance class correspond to the ISO designation to preserve cutting angles and seat integrity. For operators less familiar with coating technologies: PVD (physical vapour deposition) applies a thin, hard layer that improves abrasive wear resistance while preserving edge sharpness—a practical advantage for machining rostfreier Stahl.
