CCMT09T304 T6215 ISO Turning Insert — CVD-coated carbide, 80° rhombic (Tungaloy)

CCMT09T304 T6215 is an ISO‑standard indexable turning insert designed for external and internal turning operations, optimised for stainless steel under stable to lightly interrupted conditions.

• CVD-coated carbide for wear resistance
• Suitable for turning rostfreier Stähle
• Rhombic 80° geometry, 0.4 mm corner radius
• Cylindrical hole with 40°–60° countersink

Durable cutting performance for stainless steel machining

The insert's CVD-coated carbide grade T6215 is developed for wear resistance in demanding turning tasks. The chemical vapour deposition layer increases resistance to adhesive and abrasive wear, which helps to maintain edge stability during continuous cuts. For operations on stainless steels, this coating reduces work hardening at the cutting edge and supports a steady material removal rate. Those seeking fewer tool changes and consistent surface quality will benefit from the combination of substrate and coating, which translates into improved uptime and predictable tool life.

Geometry and mounting that promote stable cuts

The rhombic 80° plate form with a 0.4 mm corner radius and 7° clearance delivers a balance between edge strength and cutting sharpness. The plate thickness of 3.97 mm adds rigidity, while the cylindrical hole with a 40°–60° countersink ensures secure clamping in compatible ISO holders. A single-sided chipbreaker assists chip control when machining with stable setups; selecting the appropriate chipbreaker and grade helps to avoid built-up edge and supports consistent surface finish. Compatibility with a holder is determined by form, clearance angle, tolerance class, fastening method, size and thickness, so correct holder selection is essential for best results.

Productivity gains and predictable tool life

Using a purpose‑matched grade and geometry reduces the need for frequent tool changes and rework. Under the recommended cutting conditions, the insert supports consistent dimensional accuracy and surface finish, which contributes to shorter cycle times and lower per‑part tooling costs. The wear behaviour of the T6215 grade supports a steady flank wear progression rather than sudden chipping, meaning maintenance intervals can be scheduled reliably. For manufacturers aiming to increase throughput while maintaining repeatable component quality, this insert provides a cost‑effective route to stable production.

System advice and selection guidance

The insert is part of a system comprising the ISO turning insert, a matching external holder or boring bar, an underlay/clamping set and replacement screws. Choosing the correct combination—insert grade, chipbreaker, and holder stability—depends on workpiece material, machining strategy and machine rigidity. For specific applications or to confirm holder compatibility, Metav Werkzeuge offers technical advice and can supply the required clamping components and spare fixation screws. Technical data such as clearance angles and hole style should be checked against the intended holder before assembly to ensure safe and repeatable operation.

FAQ

Which materials is this insert intended for?
The CCMT09T304 T6215 insert is designed primarily for machining stainless steels, where the CVD coating enhances wear resistance and reduces built‑up edge.

What determines holder compatibility for this insert?
Compatibility is governed by plate form, clearance angle, tolerance class, fastening method, plate size and thickness; the CCMT09T304 requires an ISO holder matching these parameters.

For what cutting conditions is the T6215 grade recommended?
T6215 is optimised for stable to lightly interrupted turning operations, offering a balance of wear resistance and edge stability for continuous machining of stainless steels.

What role does the chipbreaker play on this insert?
The single‑sided chipbreaker aids chip control in stable setups; selecting a chipbreaker adapted to the workpiece and machining stability improves surface finish and reduces problems with long chips.

Can this plate be used for internal turning as well as external turning?
Yes, the ISO‑standard geometry of the plate makes it suitable for both external and internal turning when paired with the correct holder and boring bar.
