CPMT 090304 AH6225 – Tungaloy indexable insert for turning

The CPMT090304 AH6225 is an ISO‑standard rhombic indexable insert for external and internal turning, optimised for stainless steels and medium machining with a sharp yet stable cutting edge.

• ISO rhombic insert CPMT 09 size
• PVD-coated AH6225 for stainless steels
• Single-sided chipbreaker and countersunk hole
• Secure seating with precise 11° clearance angle

Consistent performance for stainless-steel turning

The PVD coating combined with the AH6225 grade on a cemented carbide substrate delivers a balance of wear resistance and edge stability for variable cutting conditions. This composition supports a sharp cutting edge that resists built-up edge formation when machining austenitic and other stainless steels, reducing the need for frequent index changes. The result is improved process reliability and longer effective tool life, which together translate into fewer interruptions and more predictable cycle times on the shop floor.

Secure clamping and effective chip control for reliable production

The rhombic geometry with a defined 11° clearance angle and a corner radius of 0.4 mm ensures repeatable seating in ISO‑compliant holders; the insert’s cylindrical hole with one-sided countersink (40°–60°) provides positive locating and clamping stability. The single-sided chipbreaker guides chips away from the cutting zone, lowering the risk of entanglement and minimising rework. Clear mechanical location and reliable chip control reduce setup time and contribute to consistent surface finish and dimensional accuracy during serial production.

System setup and process advantages for shops

As part of an ISO‑based system, the insert functions together with a matching external holder or boring bar, the correct underlay/clamp set and replacement screws for safe operation. The plate thickness of 3.18 mm and the standard CPMT size allow easy replacement across common clamping systems. For practical use, select the chipbreaker and grade according to material, cutting parameters and machine stability; this approach optimises cutting forces and extends edge life, making the tooling solution cost‑effective for medium turning tasks while maintaining high process safety.
