CPMT 090308 AH6225 — ISO turning insert for turning by Tungaloy

The CPMT090308 AH6225 is an ISO‑standard rhombic indexable insert intended for external and internal turning, optimised for machining stainless steels under varying cutting conditions.

• ISO‑standard rhombic insert 09
• PVD‑coated cemented carbide grade AH6225
• Sharp yet stable cutting edge for stainless steel
• Compatible with holders with 11° clearance

Consistent performance on stainless steels and mixed batches

The insert is supplied in a PVD‑coated cemented carbide grade (AH6225), developed for a balance between edge sharpness and robustness. This combination reduces the tendency for work hardening on stainless steel and maintains cutting stability under interrupted cuts or variable feeds. The PVD coating increases wear resistance while preserving a keen edge, which translates into longer in‑service intervals and more predictable component tolerances. This makes the insert particularly suitable for shops facing frequent material changes or medium‑duty series production.

Precise geometry for predictable surface finish and tool life

Designed as a rhombic 09 insert with an 11° clearance angle and a 0.8 mm corner radius, the geometry supports repeatable insert seating and a defined chip flow. The combination of corner radius and clearance angle enables a reliable surface finish without excessive cutting forces in common turning operations. The insert’s indexable design facilitates quick orientation changes on the toolholder, reducing downtime and simplifying tool management. Compatibility with ISO‑standard holders ensures straightforward integration into existing turning setups.

Practical selection and integration for productive turning

The insert accepts a cylindrical hole with a one‑side countersink (40°–60°), permitting simple clamping with standard screws and clamping sets. Select the matching chipbreaker and grade according to the workpiece material and process stability: a one‑sided chipformer in this insert suits many turning routines, but matching holder rigidity and appropriate feeds will enhance tool life. Where higher thermal loads or abrasive conditions occur, the PVD coating and cemented carbide composition support sustained performance. For shops seeking to reduce setup variability, the ISO conformity of the insert simplifies spare‑part management and holder interchangeability.

FAQ

Is this insert suitable for stainless steels? Yes. The CPMT090308 AH6225 insert uses a PVD‑coated cemented carbide grade optimised for stainless steel machining, offering a balance of a sharp edge and stability for medium cutting conditions.

Which toolholders are compatible with this ISO insert? Compatibility is determined by the ISO form, insert size (09), thickness (3.18 mm), hole style and tolerance class; the CPMT090308 fits ISO‑compatible holders designed for rhombic 09 inserts with an 11° clearance.

How does the AH6225 grade affect performance? AH6225 provides enhanced wear resistance through its PVD coating while maintaining a sharp cutting edge, resulting in improved edge stability and longer tool life in mixed or variable turning conditions.

What advantages does the 0.8 mm corner radius provide? A 0.8 mm corner radius helps produce a consistent surface finish and distributes cutting forces to reduce edge chipping during moderate depth‑of‑cut operations, supporting dimensional stability.
