CPMT 09T308 T6215 indexable turning insert, CVD-coated carbide — Tungaloy

CPMT 09T308 T6215 is an ISO-standard rhombic turning insert optimised for external and internal turning of stainless steels, designed for stable to mildly interrupted cuts.

• CVD-coated carbide for high wear resistance
• Rhombic ISO form CPMT for versatile turning
• 11° clearance angle for secure cutting geometry
• Single-sided chipbreaker, cylindrical hole with countersink

Durable coating and substrate for longer tool life

The insert combines a CVD-coated surface and a carbide substrate to deliver high wear resistance and consistent edge retention when machining stainless steels. The coating reduces adhesive wear and improves surface finish, while the carbide core maintains edge stability under steady cutting conditions. This results in fewer tool changes and more predictable production cycles, making the insert a cost-effective choice for shops aiming for sustained productivity.

Precise geometry for predictable compatibility and clamping

Manufactured to ISO-standard dimensions, the rhombic indexable insert offers a defined form, radius and thickness that determine compatibility with holders. The 11° clearance and a corner radius of 0.8 mm provide a balanced cutting edge for finishing and semi-finishing operations. The insert features a cylindrical hole with a single-sided countersink (40°–60°) to ensure stable clamping and repeatable seating; correct matching of holder form, tolerance class and fastening method is essential to achieve the expected cutting performance.

Application guidance and efficiency in turning stainless steels

With a single-sided chipbreaker tailored to the T6215 grade, this insert controls chip formation during turning and reduces the risk of built-up edge when machining work-hardening alloys. The grade is intended for stable to slightly interrupted conditions and is suitable for both external and internal turning. Selecting feeds and speeds that respect workpiece material and machine rigidity maximises tool life and surface quality — the coating and substrate combination supports consistent results across series production.

FAQ

What materials is this insert best suited for?
The CPMT 09T308 T6215 insert is formulated for machining stainless steels and performs well in stable to mildly interrupted turning operations.

How does the hole and countersink affect clamping?
The cylindrical hole with a one-sided countersink (40°–60°) ensures secure and repeatable seating in compatible ISO holders, improving stability and reducing vibration during cutting.

Which chipbreaker type does the insert have and why is it important?
This insert features a single-sided chipbreaker; it is designed to control chip formation when turning stainless steels, assisting in evacuation and reducing built-up edge.

Is the CPMT 09T308 compatible with existing ISO holders?
Compatibility depends on matching the insert form, clearance angle, tolerance class, fastening method, size and thickness; when these align, the insert seats and clamps correctly in standard ISO holders.
