CCMT09T308 T6215 rhombic turning insert by Tungaloy — CVD-coated carbide for stainless steel

The CCMT09T308 T6215 is a CVD-coated indexable insert designed for turning applications on stainless steel under stable to slightly interrupted machining conditions, compatible with ISO holders matching form, clearance and tolerance.

• CCMT09T308 rhombic insert, 80° geometry
• CVD-coated carbide grade T6215 for stainless steel
• 0.8 mm nose radius for fine surface finishes
• Cylindrical hole with single-side chipbreaker

Consistent high-performance machining of stainless steel

The combination of a CVD-coated surface and the T6215 carbide matrix yields a wear-resistant cutting edge optimised for the demands of machining stainless steel. This treatment improves thermal and abrasive resistance, which in turn prolongs edge life and reduces the frequency of insert changes. For production environments where uptime and predictable tool life matter, the coating and substrate pairing support higher cutting parameters while maintaining consistent results. The ISO-designated insert is aimed at external and internal turning tasks, where stable chip formation and controlled wear are priorities.

Geometry engineered for repeatable accuracy and surface quality

Featuring an 80° rhombic shape with a 0.8 mm nose radius and a 7° clearance angle, the insert provides a balanced contact zone that supports dimensional stability and surface finish. The 3.97 mm plate thickness adds stiffness in the clamp, reducing vibration in medium-duty turning operations. The cylindrical hole with one-sided countersink (40°–60°) ensures secure fastening in the pocket and consistent seat position, which is essential for repeatable tool offsets and reliable toolpath programming. These geometric details translate into fewer regrinds and more predictable cycle times.

Durable chip control and process efficiency

A single-sided chipbreaker matched to the grade helps evacuate chips effectively and reduces the risk of built-up edge when machining stainless steel. Under stable to slightly interrupted cutting, this design promotes steady chip flow and lowers the chance of surface damage, so cycle times remain efficient and downstream processes benefit from improved workpiece quality. When considered against throughput, the robust edge preparation and coating deliver a favourable tool-life-to-cost ratio, helping to lower overall machining costs in batch production and intermittent series.

System compatibility and straightforward handling

The insert integrates into standard ISO turning systems: an insert body, matched external holder or boring bar, backing/clip set and replacement screws form the complete assembly. Compatibility depends on insert form, clearance, tolerance class, fixing method, size and thickness; verifying these parameters with the chosen holder ensures correct seating and safe clamping. Spare screws and underplates should match the insert hole and countersink style for reliable mounting. For applications requiring adaptation—such as light interruptions or mixed material batches—adjusting cutting data and selecting the appropriate chipbreaker variant will maintain process security.

FAQ

What materials is this insert intended for?
The CCMT09T308 T6215 insert is formulated for machining stainless steel, offering enhanced wear resistance and chip control suited to that material class.

Is the insert compatible with standard ISO holders?
Compatibility is determined by insert form, clearance angle, tolerance class, fixing and thickness; the CCMT09T308 is ISO dimensioned and fits holders designed for CCMT inserts when those parameters match.

What benefits does the T6215 grade provide?
The T6215 CVD-coated carbide grade delivers good wear resistance and stable cutting behaviour for turning operations on stainless steel under stable to slightly interrupted conditions.

How does the chipbreaker affect performance?
The single-sided chipbreaker promotes consistent chip formation and evacuation, reducing built-up edge risk and improving surface quality in continuous turning.

Which cutting data adjustments are recommended for stainless steel?
When using the CCMT09T308 T6215 insert, moderate speeds and increased feed for thermal stability, together with appropriate coolant strategy, will typically yield the best compromise between productivity and tool life.
