CPMT 09T302 AH6225 turning insert — rhombic ISO insert for turning, PVD-coated carbide, 11° relief, with hole — Tungaloy

The CPMT09T302 AH6225 Tungaloy insert is an ISO-format rhombic turning insert designed for external and internal turning, optimised for stainless steel and medium cutting conditions.

PVD-coated carbide grade AH6225 for robustness Specifically designed for stainless steel machining Rhombic ISO 09 geometry with 80° included angle 0.2 mm corner radius and 11° relief for balanced performance

Consistent machining performance with a universal cutting grade

The PVD-coated AH6225 grade delivers a reliable compromise between edge sharpness and wear resistance, which is particularly beneficial when machining stainless steel under varying conditions. The surface coating reduces built-up edge and improves thermal resistance, enabling sustained cutting at moderate feeds and speeds. By choosing this grade, shops gain repeatable tool life and fewer insert changes, improving throughput and reducing unplanned downtime.

Geometry and chip control that support process stability

The rhombic ISO 09 shape and one-sided chipbreaker are tailored to provide reliable chip formation and evacuation during both external and internal turning. The 80° included angle increases cutting edge strength in interrupted cuts, while the cylindrical hole with single-sided countersink (40°–60°) ensures secure clamping in compatible holders. These features help maintain consistent surface finish and reduce the risk of vibration-related defects in the workpiece.

ISO compatibility for straightforward system integration

Produced to ISO standards for indexable turning, the insert integrates into common tool systems when matched for form, relief angle and tolerance class. The typical tool system comprises an appropriate external holder or boring bar, a shim/clamp set and replacement screws. This interoperability simplifies stocking and tooling decisions, allowing existing fixtures to be reused and reducing the need for special adapters.

Balanced edge geometry for medium cutting and application guidance

With a 0.2 mm corner radius, 11° relief and a 3.97 mm plate thickness, the insert balances cutting-edge sharpness with mechanical strength, making it suitable for medium-depth turning where a stable edge is required. Select the chipbreaker and clamping arrangement according to part rigidity and cutting parameters; the CPMT09T302 AH6225 insert performs best when matched to the workpiece stability and the chosen cutting data, helping to achieve predictable cycle times and surface quality.

FAQ

What material is this insert best suited for?
The CPMT09T302 AH6225 insert is optimised for machining stainless steel, offering a universal performance profile for medium turning.

How does the AH6225 grade affect tool life?
The AH6225 PVD-coated carbide provides enhanced edge stability and thermal resistance, which generally extends tool life in mixed or demanding stainless steel applications.

Which holder types are compatible with this ISO insert?
Compatibility depends on form, relief angle, tolerance class, clamping and thickness; the CPMT09T302 integrates with standard ISO-compatible external holders and boring bars when these parameters match.

What benefits does the 0.2 mm corner radius offer?
A 0.2 mm corner radius strikes a balance between edge strength and finish quality, reducing edge chipping while still permitting good surface integrity during medium cuts.

Is the insert suitable for internal turning?
Yes, the geometry and chip control characteristics make the insert suitable for both external and internal turning operations when the correct holder and setup are used.
