CPMT09T308 AH6225 indexable turning insert — PVD-coated carbide, 80° geometry — Tungaloy

The CPMT09T308 AH6225 indexable turning insert for ISO-system turning, designed for stable, medium-duty machining of stainless steels and suitable for both external and internal turning operations

• PVD-coated AH6225 grade
• Sharp, durable cutting edge
• 80° rhombic geometry for turning
• Suitable for stainless steel machining

Proven machining performance for stainless steels

The CPMT09T308 insert combines a PVD-coated carbide substrate with the AH6225 alloy to deliver a sharp yet robust cutting edge optimised for rostfrei (stainless) steels. The coating enhances wear resistance and thermal stability, which translates into longer tool life and fewer index changes on high-mix production runs. Because the grade is conceived for varying conditions, it supports stable chip formation across interrupted cuts and changing feeds, reducing the risk of unexpected edge breakage and improving process repeatability in serial production.

Secure clamping and geometry that improves surface quality

The 80° rhombic geometry and 0.8 mm nose radius provide a balance between strength and finish capability: the acute angle allows good access to profiles while the nose radius supports a consistent surface finish. The insert includes a cylindrical hole with single-sided countersink (40°–60°) for secure fastening; compatibility with the toolholder depends on form, clearance angle, tolerance class, fastening method, size and thickness. With a 11° clearance angle and a plate thickness of 3.97 mm, the geometry helps to damp vibrations and maintain a steady cutting line, which benefits both productivity and the final component tolerances.

Practical selection and process benefits

Select the one-sided chipbreaker and the AH6225 grade to match feed, depth of cut and the stability of the setup for the best economy per part. The insert is part of an ISO system that makes indexing quick and reduces machine downtime, improving overall throughput. For workshops seeking predictable performance, this insert supports a cost-effective strategy by combining good wear resistance, broad material coverage and straightforward indexing.

FAQ

What materials is this insert suitable for?
The CPMT09T308 AH6225 insert is formulated for stainless steels, offering stable chip control and wear resistance on a broad range of austenitic and martensitic grades.

How does the AH6225 grade benefit machining?
AH6225 is a PVD-coated carbide grade that provides a sharp, stable cutting edge with improved heat resistance and wear life, making the insert reliable for medium machining and variable conditions.

Which holders are compatible with this insert?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; the insert follows ISO geometry to ensure interchangeability with ISO-type external and internal turning holders.

Can the insert be used for finishing?
Yes. The 0.8 mm nose radius and 80° geometry enable satisfactory surface finishes when appropriate feeds and speeds are selected; choose a finer feed and stable clamping for finishing passes.

What is the purpose of the single-sided chipbreaker?
The one-sided chipbreaker is optimised to control chip shape and evacuation during turning, reducing the risk of built-up edge and improving machining stability on stainless steels.
