CPMT09T304 AH6225 Tungaloy insert — ISO rhombic turning insert for stainless steels

A CPMT09T304 indexable insert designed for external and internal turning, offering a balanced cutting edge for medium-duty machining of stainless steels

• PVD-coated carbide AH6225 for stainless steels
• ISO rhombic insert with 80° cutting edge
• 0.4 mm corner radius for consistent finishes
• Cylindrical hole with single-side countersink
• 11° clearance angle, 3.97 mm plate thickness

Stable cutting performance for stainless steels

The PVD-coated AH6225 grade provides a reliable mix of edge sharpness and wear resistance optimised for stainless steels in variable production environments. By combining a hard, wear-resistant coating with a tough carbide substrate, the insert sustains a stable cutting edge under interrupted cuts and fluctuating feeds, which helps to maintain surface quality and reduce rework. The result is a measurable improvement in process stability during medium-range turning operations.

Geometry engineered for precise surfaces and tool life

A 0.4 mm corner radius and an 80° cutting edge geometry support predictable load distribution and fine finishing capability. The 11° clearance angle reduces flank contact while preserving edge strength, making the insert suitable for operations that require consistent dimensional control. With a plate thickness of 3.97 mm, the indexable part offers sufficient rigidity in the clamping zone to resist chatter and provide repeatable tool life across batches.

Integrated chip control and mounting details for productive turning

The single-sided chipbreaker and the cylindrical hole with one-sided countersink (40°–60°) aid reliable chip evacuation and secure clamping in compatible holders. Good chip control shortens cycle interruptions and lowers the risk of surface blemishes, especially when machining long, springy stainless bars. The ISO-format design ensures compatibility with a wide range of standard external holders and boring bars when the correct form, relief, tolerance class, attachment method, size and thickness are matched.

Application guidance and selection criteria

As an ISO indexable insert, the component is intended for both external and internal turning; the correct selection of chipbreaker and grade depends on workpiece material, machining strategy and machine/tool stability. The ISO designation and rhombic form make it straightforward to compare sizes and fit holders, while the PVD layer and carbide core warrant long tool life under typical mixed-duty cycles. For changed conditions, choose a chipbreaker and cutting data aligned to feed, depth of cut and coolant strategy to maximise productivity.

FAQ

Is this insert suitable for continuous stainless steel turning?
The CPMT09T304 AH6225 insert is formulated for stainless steels and performs well in continuous medium-duty turning when cutting data and holder rigidity are matched to the application.

What does the AH6225 grade offer compared with other grades?
AH6225 is a PVD-coated carbide grade that balances sharpness and durability for stainless steels, providing stable edge life under mixed cutting conditions.

Can the insert be used for internal boring as well as external turning?
Yes, the ISO rhombic form and the specified geometry allow use in both external and internal turning operations, provided the correct holder and clamping arrangement are selected.

How does the single-sided chipbreaker affect machining?
The single-sided chipbreaker improves chip control for typical turning tasks and helps reduce re-cutting of chips, leading to more consistent surface quality and fewer cycle interruptions.
