CPMT 090304 AH6235 Tungaloy turning insert — PVD‑coated carbide, 0.4 mm radius

CPMT090304 AH6235 is a rhombic indexable insert designed for precision turning in a wide range of industrial applications, particularly where interrupted cuts and stainless steel machining demand a tougher grade.

• PVD-coated carbide AH6235 for stainless steel machining
• Rhombic CPMT geometry 80° for versatile turning
• 0.4 mm nose radius for precision finishing

Tough grade for demanding stainless steel and interrupted machining

The PVD-coated carbide grade AH6235 has been developed for increased toughness, making it suitable for the elevated breakout risk associated with machining stainless steel and interrupted cuts. The deposit layer improves resistance to built-up edge while the substrate material maintains edge stability under variable cutting forces. This results in fewer unplanned tool changes and more predictable production cycles, which supports higher throughput and lower scrap rates.

Geometry and dimensions that simplify holder selection and repeatability

Designed to the ISO CPMT090304 specification, the insert features a rhombic form with an 80° approach angle and 11° clearance. The 0.4 mm corner radius and 3.18 mm thickness provide a balance between accuracy and robustness for both finishing and light roughing. Compatibility with toolholders is determined by form, clearance angle, tolerance class, fastening method, size and thickness, so correct matching ensures secure clamping and repeatable results with minimal setup time.

Practical chip control and system integration for shopfloor efficiency

A one-sided chipbreaker and the centre cylindrical hole with a single-sided countersink (40°–60°) support consistent chip formation and evacuation in many turning scenarios. The insert is intended to be used as part of a system comprising the indexable insert, appropriate external holder or boring bar, shim/clamping set and spare screws, enabling quick replacement and reduced downtime. Improved chip control and the tougher grade together contribute to prolonged tool life and steadier surface finishes.

FAQ

What materials is this insert optimised for?
The CPMT090304 AH6235 insert is optimised for stainless steel and performs well in applications with interrupted cuts or elevated breakout risk.

Which toolholders are compatible with this geometry?
Compatibility is achieved with holders designed for the CPMT form; the holder must match the insert form, clearance angle, tolerance class, fastening type, size and thickness for secure clamping and repeatable results.

What is the nose radius and how is it used?
The corner radius is 0.4 mm, suitable for precision finishing and controlled light roughing where fine surface quality is required.

How does the coating and grade affect performance?
The PVD-coated AH6235 grade provides enhanced toughness and edge stability, reducing the likelihood of chipping and supporting consistent chip control in demanding workpieces.

Can the insert be used for internal and external turning?
Yes; the insert is suitable for both external and internal turning when paired with the correct external holder or boring bar and clamping set.
