CPMT09T308 T9215 CPMT — Turning insert, CVD‑coated carbide, R0.8 (Tungaloy)

The CPMT09T308 T9215 is an ISO rhombic turning insert designed for medium‑steel machining, offering a single‑sided chipbreaker and secure clamping via a cylindrical hole with one‑sided countersink.

• CVD‑coated carbide grade T9215
• Rhombic ISO size 09, R0.8
• 11° clearance angle
• Cylindrical hole with one‑sided countersink

Improved productivity for medium‑steel turning

The ISO‑format insert combines a CVD‑coated cutting surface with a carbide substrate to balance wear resistance and fracture toughness for sustained machining. The chosen grade, T9215, is optimised for medium steel, enabling longer uninterrupted runs and reliable performance in continuous and light interrupted cuts. For production environments the result is fewer indexings and reduced tool change frequency, which translates directly into higher process throughput and predictable cycle times.

Robust geometry for consistent surface quality

The insert’s R0.8 corner radius and 11° clearance reduce edge chipping while maintaining cutting engagement, supporting a consistent surface finish on turned components. The rhombic form permits both external and internal turning when mounted in a compatible holder, and the 3.97 mm thickness gives the insert the rigidity required to resist vibration under moderate feeds. The single‑sided chipbreaker controls chip flow to prevent entanglement and to aid continuous chip evacuation, which helps to protect the workpiece and toolholder from unexpected damage.

Secure clamping and easy holder compatibility

Compatibility with a toolholder is determined by insert form, relief geometry, tolerance class, clamping method, nominal size and thickness. This insert features a cylindrical hole with a one‑sided countersink (40°–60°) for positive, repeatable clamping and quick indexability. Selecting the matching chipbreaker style and the T9215 grade for the correct cutting data ensures economical cutting tool life and consistent component quality. For tailored recommendations on holder selection and cutting parameters, the technical advisers at Metav Werkzeuge provide practical support and documented cutting data.

FAQ

Is this insert suitable for interrupted cuts?
The CPMT09T308 T9215 insert is designed for continuous and light interrupted cuts; for heavy interruptions a different grade or chipbreaker may be preferable.

Which materials is this grade best for?
The T9215 CVD‑coated grade is optimised for medium steels, offering a balance of wear resistance and fracture toughness for productive machining.

How does the hole and countersink affect clamping?
The cylindrical hole with a one‑sided countersink (40°–60°) ensures repeatable clamping and stable positioning in compatible toolholders, improving repeatability of the insert seating.

Can this insert be used for both external and internal turning?
Yes, the rhombic geometry permits both external and internal turning operations when paired with a suitable holder and correct cutting data.

What should be considered when selecting a chipbreaker?
Select the chipbreaker according to material, cutting mode and stability; this insert’s single‑sided chipbreaker supports controlled chips in typical turning of medium steels.
