CCMT09T308 AH6225 Tungaloy turning insert – PVD-coated carbide, 0.8 mm corner radius

The CCMT09T308 AH6225 is an ISO-standard rhombic turning insert designed for external and internal turning, offering a sharp yet stable cutting edge for medium machining of stainless steels.

• ISO rhombic insert CCMT09T308 AH6225
• PVD-coated carbide for stainless steel
• 0.8 mm corner radius, 80° cutting angle
• Cylindrical hole with 40°–60° countersink

Increased productivity with a universal cutting grade

The AH6225 grade, delivered as a PVD-coated cemented carbide insert, combines edge sharpness and robustness to handle medium cutting depths and fluctuating machining conditions. This balance reduces the need for frequent tool changes and supports longer uninterrupted runs, which in turn improves process efficiency on stainless-steel parts. The sharp, stable cutting edge minimises built-up edge formation in many common stainless alloys, while the coating supports thermal and abrasive resistance during sustained operation.

Reliable clamping and repeatable geometry for consistent results

Manufactured to ISO dimensions, the insert’s rhombic geometry and 80° cutting angle ensure straightforward compatibility with standard holders; fit is governed by form, clearance angle, tolerance class, attachment and plate thickness. The central cylindrical hole with a single-sided countersink (40°–60°) facilitates secure clamping and repeatable seating, reducing setup variability. The 3.97 mm thickness and precise tolerances contribute to stable cutting behaviour and predictable tool life when paired with appropriate underlay, clamping set and replacement screws.

Application benefits and machining guidance

A 0.8 mm corner radius delivers a compromise between edge strength and profile definition: it supports modest radii required for finishing while preserving robustness under interrupted cuts. The one-sided chipbreaker assists in controlling chip formation for many turning tasks, helping to protect the insert’s edge and the workpiece surface finish. Intended for turning operations, the insert is suitable for both external and internal work when combined with a matching ISO holder.

FAQ

What materials is this insert suitable for?
The CCMT09T308 AH6225 insert is formulated for machining stainless steels; the AH6225 grade and PVD coating offer a good balance of edge stability and wear resistance for medium turning operations.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm corner radius increases edge strength compared with smaller radii, providing improved resistance to chipping during interrupted cuts while still allowing acceptable surface finishes for general turning tasks.

Is the insert compatible with ISO holders?
Yes. The insert conforms to ISO dimensions (CCMT09T308) and requires a holder that matches form, clearance angle, tolerance class, attachment and thickness — the ISO-standard geometry ensures broad compatibility.

What fastenings and clamping features does this insert require?
The insert features a central cylindrical hole with a single-sided countersink (40°–60°) and is intended to be used with a matching underlay or clamping set and replacement screws for secure seating.
