CPMT 090308 AH6235 – ISO turning insert by Tungaloy, PVD‑coated carbide for turning

The CPMT090308 AH6235 is an ISO‑format turning insert designed for external and internal turning, offering a tougher PVD‑coated carbide grade for stainless steels and interrupted cutting conditions.

• PVD-coated carbide grade AH6235
• For stainless steel and interrupted cuts
• Rhombic ISO CPMT090308, 0.8 mm corner radius
• Cylindrical hole with one-sided countersink

Optimised cutting performance for stainless steels

The combination of a PVD-coated carbide substrate and the AH6235 grade delivers a balance of toughness and wear resistance tailored to machining stainless steel. The coating increases thermal and abrasion resistance while the tougher substrate reduces the risk of edge chipping during interruptions in the cut. This results in more predictable tool life and fewer unscheduled indexings, which supports a smooth production flow and reduces cost per part. The design is particularly suited to applications where material adhesion and work hardening are concerns.

Stable edge geometry for reliable surface quality

A rhombic ISO CPMT090308 geometry with a 0.8 mm corner radius and an 11° clearance creates a stable cutting edge that withstands moderate engagement and intermittent forces. The insert’s single-sided chipbreaker promotes controlled chip formation on softer and adhesive materials, improving surface finish and reducing built-up edge formation. The insert thickness of 3.18 mm and the 80° lead angle contribute to a secure clamping condition and reduced vibration, supporting consistent dimensional accuracy and repeatable results in series production.

System compatibility that simplifies tool selection

ISO standardisation ensures straightforward integration into existing tool systems, but compatibility depends on holder shape, clearance angle, tolerance class, fixing method, size and thickness. The cylindrical hole with a one‑sided countersink (40°–60°) provides positive, repeatable seating in many common clamping systems. Selecting the correct chipbreaker and the AH6235 grade for the workpiece stability and cutting conditions will extend life and reduce downtime. For complex setups or to match this insert to a specific holder, consult Metav Werkzeuge for tailored advice and verified component pairing.
