CPMT 090308 AH6235 indexable insert for Turning — PVD-coated carbide, 80° rhombic, Tungaloy

The CPMT090308 AH6235 is an ISO rhombic indexable insert intended for turning applications, optimised for stainless steel and resistant to interrupted cutting conditions.

• PVD-coated carbide grade AH6235
• Optimised for stainless steel and interrupted cuts
• Rhombic ISO insert, 80° geometry, 0.8 mm radius
• Cylindrical hole with 40°–60° single-side countersink

Durable coating and grade for reduced breakouts and longer runtimes

The insert uses a PVD-coated carbide substrate in the AH6235 grade, a tougher formulation designed specifically for machining stainless steel and other challenging alloys. The PVD coating enhances edge strength and wear resistance, which lowers the risk of edge chipping during interrupted cuts and helps maintain a predictable wear pattern. This combination improves component quality and reduces unplanned tool changes, supporting more stable production cycles.

ISO conformity and secure clamping for predictable set-up

Manufactured to ISO standards, the plate’s rhombic form and defined 80° geometry allow straightforward matching to compatible holders. The insert features a cylindrical hole with a single-side countersink (40°–60°) to ensure reliable screw engagement and repeatable clamping. With clearly defined dimensions such as 3.18 mm plate thickness and standard tolerances, this solution simplifies tool inventory management and contributes to reproducible machining results.

Geometry and corner radius tuned for finishing and interrupted operations

The 0.8 mm corner radius balances strength and surface finish: it provides a robust cutting edge for intermittent engagement while still permitting high-quality surfaces in finishing passes. The one-sided chipbreaker supports controlled chip formation under varying feed and depth conditions; selection of the correct chipbreaker and holder rigidity will directly influence achievable surface quality and machining stability in both external and internal turning.

Practical benefits for productive turning cells

As part of an ISO insert system, this plate integrates with standard external holders, shims and clamping kits to reduce changeover time and minimise set-up variability. The tougher grade and coating combination aims to increase cutting edge life, which contributes to lower tool consumption and fewer interruptions. For process-planning, the insert’s characteristics support a rational approach to cycle-time reduction and consistent batch output.

FAQ

What materials is this insert best suited for?
The CPMT090308 AH6235 insert is optimised for stainless steel and other materials prone to built-up edge; the AH6235 grade and PVD coating support interrupted cutting and improve edge stability.

How does the AH6235 grade affect tool life?
AH6235’s tougher carbide matrix with PVD coating increases resistance to chipping in the CPMT090308 insert, which often extends usable edge life under unstable cutting conditions.

Which insert geometry should be matched with a holder?
Select a holder designed for ISO rhombic plates with an 80° seating; correct relief angle and tolerance class alignment ensure secure clamping of the CPMT090308 insert.

Can this insert be used for both external and internal turning?
Yes, the insert’s geometry and chipbreaker are suitable for both external and internal turning operations when paired with the correct holder and machining parameters.

What benefit does the 0.8 mm corner radius provide?
The 0.8 mm radius offers a compromise between edge strength for interrupted cuts and the ability to achieve a good surface finish in finishing passes when using the CPMT090308 AH6235 insert.
