CCMT 09T302 T6215 turning insert — CVD-coated carbide, 80° rhombic (Tungaloy)

CCMT 09T302 T6215 is an ISO-format indexable insert designed for external and internal turning, optimised for stainless steel in stable to lightly interrupted cutting conditions.

• CVD-coated carbide for stainless steel machining
• Rhombic 80° geometry for versatile turning
• 0.2 mm corner radius for controlled finishing
• Single-sided chipbreaker with countersunk hole

Increased productivity and extended tool life in stainless steel turning

The combination of a CVD coating and a wear-resistant carbide substrate delivers consistent performance when machining stainless steel. The coating reduces flank wear and improves heat resistance, which prolongs cutting edge life and lowers tool-change frequency. As a result, cycle times are reduced and machine availability increases. For customers running medium-volume production, this means less downtime and a more predictable tool consumption pattern—direct benefits for production planning and cost control.

Geometry that stabilises cuts and improves surface finish

The 80° rhombic geometry with a 0.2 mm corner radius provides a balance between strength and finishing capability. The acute geometry allows controlled chip formation and accessibility in shoulder and profile turning, while the small corner radius supports fine surface quality without sacrificing edge robustness. This geometry is especially suitable where dimensional consistency and surface integrity are required, reducing rework and downstream polishing operations.

Reliable chip control and mounting features for consistent results

A single-sided chipbreaker combined with the insert’s cylindrical hole and one-sided countersink (40°–60°) supports predictable chip flow and secure clamping in ISO holders. The standardised ISO form simplifies replacement and inventory management, allowing the insert to be indexed or rotated as permitted by the holder design. Stable clamping and repeatable seating contribute to process reliability and reduce the need for frequent adjustments during batch runs.

Practical suitability and recommended use cases

Designed for turning operations, the insert’s grade T6215 and CVD treatment are tailored for operations on stainless steel under steady to lightly interrupted cutting. Typical applications include external profiling, internal boring and finishing passes where a combination of wear resistance and surface quality is required. Selection of appropriate speeds, feeds and a compatible holder will enable the best compromise between tool life and productivity.
