CPMT09T308 AH120 ISO rhombic turning insert by Tungaloy — PVD‑coated carbide, 09 size

The CPMT09T308 AH120 is an ISO‑standard rhombic indexable insert designed for general turning operations where a sharp cutting edge and high process security are required.

• PVD‑coated carbide grade AH120
• ISO‑standard rhombic insert CPMT09T308
• 11° relief angle for stable cutting
• Cylindrical hole with single‑side countersink

Longer tool life through wear‑resistant grade and coating

The PVD‑coated carbide in the AH120 grade offers a balance of wear resistance and edge strength that reduces flank wear and minimises chipping under mixed cutting conditions. This results in fewer index changes and more consistent cycle times. For production environments where uptime and repeatable component quality matter, the combination of a hard coating and a robust substrate delivers measurable gains in tool life and process stability, translating into predictable maintenance intervals and lower overall tooling cost.

Geometry engineered for reliable chip control and surface quality

The rhombic geometry and the 11° relief angle support steady cutting action and reliable chip evacuation, while the 0.8 mm corner radius gives a compromise between strength and the potential for finer surface finishes. The insert’s single‑sided chipbreaker is optimised for turning tasks and helps produce controlled, segmented chips on a wide range of steels and alloyed materials. For users less familiar with insert geometry: the relief angle prevents rubbing behind the cutting edge, the corner radius determines the balance between edge robustness and finish, and the chipbreaker shapes chips to avoid entanglement and heat build‑up.

ISO compatibility and practical mounting for fast tool changes

Made to ISO dimensions, the insert fits holders that match in form, clearance angle, tolerance class, fastening method, size and thickness. The CPMT09T308 features a cylindrical hole with a single‑side countersink (40°–60°) for secure seating and repeatable clamping; the 3.97 mm plate thickness contributes to rigidity in the cutting zone. The modular system approach (indexable insert, compatible external holder or boring bar, shim and clamp set, replacement screws) simplifies inventory and makes on‑machine insert changes quick and repeatable, helping to keep setup times short and production steady.

FAQ

What materials is this insert suited for?
The CPMT09T308 AH120 is a PVD‑coated carbide insert designed for a broad range of steels and alloyed materials; the AH120 grade emphasises wear resistance and edge strength for reliable turning.

Which holders are compatible with this insert?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, insert size and thickness; the CPMT09T308 follows ISO dimensions for straightforward pairing with standard turning holders and boring bars.

How does the chipbreaker affect machining?
The one‑sided chipbreaker on this insert promotes controlled chip formation and evacuation, reducing the risk of entanglement and improving surface finish during conventional turning cuts.

What mounting features secure the insert reliably?
The insert has a cylindrical hole with a single‑side countersink (40°–60°) for firm, repeatable clamping; combined with the 3.97 mm thickness this ensures rigidity in the cutting zone for stable machining results.
