CPMT090304 AH6225 Tungaloy insert — PVD-coated carbide, 0.4 mm radius for turning

The CPMT090304 AH6225 is an ISO-standard rhombic turning insert engineered for reliable external and internal turning of stainless steels under varying conditions.

• ISO-standard rhombic insert
• PVD-coated carbide grade AH6225
• 0.4 mm corner radius
• Designed for stainless steel turning

Consistent edge stability for mixed stainless-steel work

The PVD-coated carbide grade AH6225 delivers a balance of sharpness and robustness that suits medium cutting conditions; the coating improves wear resistance while the substrate maintains a stable cutting edge. This results in predictable tool life and reduced variability in batch production, translating to fewer tool changes and less downtime. The combination of substrate and coating supports both finish and semi-finishing operations on stainless steels, helping maintain dimensional accuracy and surface quality across workpieces.

Precise geometry for predictable chip control and clamping

With a 0.4 mm corner radius and a 11° clearance angle, the insert geometry is tailored to provide reliable cutting forces and chip formation in turning operations. The rhombic plate form and the cylindrical hole with single-sided countersink (40°–60°) ensure secure seating in compatible holders and accurate repeatability during index changes. Selecting the correct single-sided chipbreaker further refines chip form for the chosen feed and depth of cut, improving process stability and reducing the risk of built-up edge formation.

System compatibility and simple selection for efficient workflow

As an ISO-standard insert, this plate integrates into established toolholder systems; compatibility depends on form, clearance, tolerance class, fastening and plate dimensions. The plate thickness of 3.18 mm and the size designation 09 align with common outside holders and boring bars, allowing straightforward replacement without extensive adapter inventories. For workshops running mixed materials, choosing this grade simplifies tooling logistics while keeping cutting performance consistent across shifts.

FAQ

What materials is this insert best suited for?
The CPMT090304 AH6225 insert is optimised for stainless steels, providing a balance of edge sharpness and wear resistance for medium cutting conditions.

How does the 0.4 mm corner radius affect machining?
A 0.4 mm corner radius increases edge strength for interrupted cuts and contributes to consistent surface finish; the CPMT090304 geometry supports stable cutting forces and predictable results.

Is this insert compatible with standard ISO holders?
Yes; the CPMT090304 is an ISO-standard rhombic insert and will fit holders designed for size 09 plates with a 3.18 mm thickness and the specified hole and countersink style.

What role does the AH6225 grade play in tool life?
The AH6225 PVD-coated carbide grade offers a compromise between wear resistance and edge sharpness, helping to extend tool life during variable stainless-steel turning while maintaining surface quality.

Can the chipbreaker be adapted for finishing or roughing?
The single-sided chipbreaker on this insert can be matched to the specific feed and depth of cut; choosing the appropriate breaker tailors chip formation for either finishing or more productive roughing passes.
