CCMT 09T308 AH6225 Tungaloy – ISO indexable turning insert for turning, PVD‑coated carbide, 0.8 mm corner radius

The CCMT09T308 AH6225 Tungaloy is an ISO‑standard indexable insert designed for external and internal turning of stainless steels, engineered to maintain a stable cutting edge under changing conditions.

• ISO‑standard rhombic insert, size 09
• PVD‑coated carbide grade AH6225
• 0.8 mm corner radius for edge strength
• Cylindrical hole with 40°–60° countersink

Consistent performance for stainless steel turning

The combination of a PVD coating and the AH6225 grade offers a balance between wear resistance and toughness, which is particularly advantageous when machining stainless steels. The coating reduces built‑up edge tendency and improves sliding properties at the chip‑tool interface, while the carbide substrate keeps the cutting edge stable under medium cutting forces. For process planners, this means fewer tool changes and more predictable component quality, translating into higher machine uptime and consistent surface finishes.

Geometry and mounting that reduce variability

The CCMT geometry (rhombic insert, size 09) with an 80° approach angle, 0.8 mm corner radius and 7° relief provides a controlled engagement and favourable force distribution at the tool tip. The insert thickness of 3.97 mm and the included cylindrical hole with a one‑sided countersink (40°–60°) ensure secure clamping in ISO holders; correct seating is defined by form, clearance angle, tolerance class and fixing method. The single‑sided chipbreaker supports consistent chip formation in turning operations, reducing risk of chatter and improving surface integrity.

System advantages and production benefits

Used as part of a matched system—insert, external holder or boring bar, shim and clamp—the indexable solution simplifies tool management and replacement. The universal nature of the AH6225 grade makes it suitable across a broad range of stainless alloys, minimising the number of tool types required in inventory. Process engineers will value the predictable tool life and steady cutting behaviour, which aid cycle time planning and reduce rework. Selecting the correct chipbreaker and maintaining a rigid setup are key to unlocking these efficiency gains.

Practical selection and setup guidance

When specifying the insert, consider the workpiece alloy and machining stability: tighter rigs and higher feed rates benefit from larger radii, while fine finishing calls for smaller corner radii. The PVD coating refers to a thin, durable layer applied in a vacuum process to enhance wear resistance; the corner radius affects both edge strength and surface finish. For the CCMT09T308 AH6225 variant, pairing with a compatible ISO holder and using the recommended clamping hardware ensures repeatable positioning and safe cutting conditions. For unfamiliar applications, testing with conservative feeds and speeds will confirm suitability before full production.

FAQ

What materials is this insert best suited for?
The CCMT09T308 AH6225 is optimised for stainless steels, combining a PVD coating with a carbide substrate to limit built‑up edge and provide reliable edge strength during medium‑duty turning.

Can this insert be used for both external and internal turning?
Yes, the rhombic CCMT shape and the single‑sided chipbreaker make this insert suitable for both external and internal turning operations when paired with the correct holder.

How should the insert be clamped to ensure repeatability?
Secure clamping using the matching ISO holder, appropriate shim and the specified fixing screw is required; the CCMT09T308’s cylindrical hole and countersink ensure positive seating and repeatable positioning.

What does the AH6225 designation mean in practice?
AH6225 denotes a PVD‑coated carbide grade tuned for a balance of toughness and wear resistance, offering a wide material coverage and stable chip formation for stainless steels.

Are there recommended cutting conditions for initial testing?
Begin with conservative feeds and moderate cutting speeds to validate the stability of the setup; once confirmed, feeds and speeds can be increased within the machine and workpiece limits to exploit the insert’s performance.
