CCMT 09T302 T6215 – CCMT indexable insert for turning (Tungaloy)

CCMT09T302 T6215 is an ISO-format indexable insert for precision turning, engineered for stable to lightly interrupted machining of stainless steel.

• CVD-coated carbide for wear resistance
• Designed for turning stainless steels
• ISO CCMT shape for broad holder compatibility
• One-sided chipbreaker for controlled chips

Durable performance for stainless steel turning

The insert combines a CVD-coated carbide grade (T6215) with a compact 0.2 mm corner radius, delivering consistent edge life when machining stainless steel under stable conditions. The carbide substrate and coating reduce flank and crater wear, which translates into longer tool life and fewer insert changes. As a result, production runs benefit from improved uptime and reduced tooling interventions, supporting efficient workshop schedules and predictable maintenance cycles.

Reliable clamping and ISO compatibility

Built in the ISO CCMT form, the insert matches common external holders and boring bars when the form, clearance angle, tolerance class, clamping method, size and thickness correspond. The rhombic profile and standardised dimensions simplify tool inventory and replacement procedures. The geometry—including an 80° included angle and a 7° clearance angle—ensures stable seating and repeatable positioning, which aids in maintaining consistent part tolerances across batches.

Coating and grade advantages explained

The T6215 grade is a CVD-coated carbide designed specifically for improved wear resistance in turning applications on stainless steels. CVD coatings provide a hard outer layer that resists abrasive wear while maintaining a tough substrate beneath to avoid premature chipping. This balance is particularly beneficial when machining tougher, work-hardening alloys common in food, medical and chemical industry components, where surface integrity and dimensional accuracy are priorities.

Practical guidance and recommended use

The insert features a one-sided chipbreaker to promote controlled chip formation and evacuation during turning, reducing the risk of built-up edge and improving surface finish. A hole with a cylindrical bore and a single-sided countersink (40°–60°) enables secure fastening and accurate seating in compatible toolholders. For optimal results, match the chipbreaker and grade to the workpiece condition and ensure stable clamping to prevent vibration; choosing the correct holder and clamping hardware will maximise the benefits of the insert’s design.

FAQ

What materials is this insert intended for?
The CCMT09T302 T6215 insert is intended chiefly for turning stainless steel, with the T6215 grade offering wear resistance suited to stable and lightly interrupted cuts.

How is the insert secured in the holder?
The insert features a hole with a cylindrical bore and a single-sided countersink (40°–60°), enabling secure clamping when combined with the appropriate screw, seat and top clamp in compatible CCMT holders.

What does the T6215 grade mean for wear and tool life?
T6215 designates a CVD-coated carbide grade optimised for wear resistance; this helps extend service intervals and supports consistent surface quality during stainless steel turning.

Is the insert compatible with all CCMT holders?
Compatibility depends on matching the insert form, 7° clearance angle, tolerance class, clamping mechanism, size (09) and thickness (3.97 mm) to the holder specifications.

Which chip control can be expected?
The one-sided chipbreaker promotes controlled chip formation and evacuation during turning, improving surface finish and reducing the risk of built-up edge under recommended conditions.
