CPMT 090308 AH6225 Wendeplatten - Tungaloy

Combining a PVD‑coated carbide grade AH6225 with an ISO rhombic 09 geometry, this insert offers a sharp yet stable cutting edge optimised for stainless steel turning. The 0.8 mm corner radius and 11° clearance ensure reliable surface finish and repeatable results in medium machining; order the CPMT090308 AH6225 insert via Metav Werkzeuge or request specialist advice if needed.

CPMT 090308 AH6225 ISO indexable insert for turning, PVD‑coated carbide — Tungaloy

A CPMT 090308 AH6225 rhombic ISO insert designed for external and internal turning of stainless steels, delivering stable cutting performance under variable conditions

• PVD-coated carbide for durability
• Grade optimised for stainless steels
• ISO rhombic 09 with 80° geometry
• 0.8 mm corner radius for fine finishes

Maximum process reliability through tailored grade and coating

The combination of a PVD‑coated surface and the AH6225 carbide composition provides a balanced balance between edge sharpness and wear resistance. In machining of stainless steels, the coating reduces adhesive wear and improves temperature resistance, which translates into more consistent tool life and fewer interruptions. The result is predictable productivity gains and a reduced need for frequent insert changes, helping to keep cycle times steady in batch and serial production.

Precise geometry for consistent surface quality and chip control

With the ISO rhombic 09 form and an 80° insert angle, the geometry is oriented towards robust engagement and good tool life in both external and internal turning. The 0.8 mm corner radius supports improved surface finish on medium passes without compromising edge strength. A single-sided chipbreaker aids controlled chip formation in varied cutting conditions; for interrupted cuts or mixed stability scenarios this layout helps avoid long stringy chips and reduces the risk of machine downtime.

Secure clamping and easy integration into ISO tool systems

The insert is supplied with a cylindrical hole and a one‑sided countersink (40°–60°) to match standard clamping systems. Combined with the typical holder, shim and screw stack, the component integrates into existing ISO toolholders with predictable seat and tolerance behaviour. The 3.18 mm thickness contributes to stable clamping and resistance to bending under load, which supports repeatable dimensional accuracy across a production run.

Practical machining guidance and selection note

This insert is specified for turning stainless steels under medium cutting conditions; select the chipbreaker and cutting data to match workpiece stability and feed range. For higher metal removal rates or different materials, consider alternative grades or geometries. Specification advice is available from Metav Werkzeuge; technical drawings, recommended cutting parameters and compatibility checks with specific holders can be supplied on request.

FAQ

Which materials is this insert best suited for?
The CPMT090308 AH6225 insert is optimised for machining stainless steels; the AH6225 grade and PVD coating are selected to give good edge stability and wear resistance for those materials.

How is the insert secured in the toolholder?
The insert uses a cylindrical hole with a one‑sided countersink (40°–60°) for screw clamping; this arrangement matches standard ISO holders when used with the recommended shim and screw.

What machining tasks is this geometry suitable for?
The rhombic 09 form with an 80° angle and a 0.8 mm radius is intended for both external and internal turning at medium cuts, offering a compromise between finish quality and edge robustness.

Does the AH6225 grade include a chipbreaker, and what is its effect?
Yes, the insert features a single-sided chipbreaker that promotes predictable chip formation and improved evacuation, which supports stable cycle times and surface consistency.
