CCMT 09T308 AH6225 — Indexable Turning Insert (ISO), PVD‑coated Carbide by Tungaloy

The CCMT09T308 AH6225 is an ISO‑standard indexable insert for turning, designed for medium cutting of stainless steels with a balanced combination of sharpness and edge stability.

• ISO‑standard rhombic insert
• PVD‑coated carbide AH6225
• For stainless steels and mixed conditions
• 80° geometry with 0.8 mm radius

Consistent machining for stainless steels and mixed batches

The combination of a PVD‑coated surface and a carbide substrate in grade AH6225 delivers a balance between wear resistance and cutting-edge sharpness, especially for stainless steels. This results in fewer interruptions for insert changes and a steadier surface finish during medium turning tasks. In practice, the coating reduces adhesive wear and improves heat resistance under variable cutting temperatures, while the substrate preserves a reliable cutting edge under intermittent loading. Such properties translate into improved process stability and can reduce total machining time for serial production and small-batch operations alike.

ISO conformity and secure fit for a wide range of holders

Built to the ISO dimensions specified by the CCMT 09T308 designation, this rhombic insert provides compatibility with holders defined by form, clearance angle, tolerance class, fastening and thickness. The 80° geometry and 7° clearance combine to give a robust cutting angle suitable for external and internal turning, while the cylindrical hole with single‑side countersink (40°–60°) ensures reliable clamping in standard clamp or screw systems. Correct matching of insert and holder reduces chatter and enables predictable repeatability across setups, simplifying tooling logistics on the shop floor.

Process advantages: chip control and tool life

The insert features a single‑sided chipbreaker tailored to medium turning operations; this aids controlled chip formation when machining ductile alloys such as stainless steels and helps protect the cutting edge during chip evacuation. The 0.8 mm nose radius provides a compromise between strength and surface finish, suitable for finishing passes or light to medium roughing where contour accuracy matters. Together, these design choices support longer effective tool life, fewer interventions and a more economical production flow — particularly valuable in high‑mix, low‑volume environments.

Practical recommendations for reliable results

Use the insert in a complete system consisting of a compatible ISO holder, clamping set and replacement screws to maintain repeatable clamping forces. Match the chipbreaker and grade AH6225 to the specific alloy and cutting parameters: slightly reduced cutting speeds and steady feed rates help when machining highly work‑hardening stainless grades. The ISO form and robust edge make the insert suited to both external and internal turning tasks; for unusual geometries or severe interrupted cuts, consider a more stable clamping arrangement or an alternative chip‑control geometry.
