CCMT 120408 T6215 Tungaloy turning insert – 80° rhombic, 0.8 mm radius

The CCMT120408 T6215 is an ISO-format indexable insert designed for external and internal turning, optimised for rostfreier Stahl under stable to lightly interrupted cutting conditions

• ISO format CCMT120408 compatible system
• CVD-coated T6215 grade for stainless steel
• Rhombic 80° geometry for stable cutting
• 0.8 mm corner radius for robustness

Durable coating and grade for predictable wear performance

The insert is manufactured from carbide and finished with a CVD‑coating in grade T6215, a combination intended to reduce abrasive wear and maintain cutting-edge integrity when machining stainless steels. This material-and-coating pairing provides a measurable improvement in tool life under consistent cutting conditions and contributes to a reliable surface quality on the workpiece. The wear behaviour of the grade allows predictable tool-change intervals, which supports cycle-time planning and reduces unscheduled downtime.

Geometry and dimensions that simplify holder selection and clamping

The ISO designation and the CCMT120408 format make the insert compatible with standard clamping systems when the holder matches the insert form, relief angle, tolerance class, clamping method, size and thickness. The 80° rhombic geometry combined with a 7° relief angle gives good edge strength with accessible cutting directions, while the 0.8 mm corner radius balances robustness and finish. At 12 mm inscribed circle and a plate thickness of 4.76 mm, the insert fits common ISO turning assemblies; secure fixation is achieved via the supplied hole arrangement and standard clamping components.

Application benefits: productivity, chip control and system planning

Equipped with a one-sided chipbreaker and a cylindrical hole with a single-sided countersink (40°–60°), this insert offers stable chip formation when matched to an appropriate holder and cutting parameters. The design supports both external and internal turning operations, particularly where stability is high or interruptions are light. Selecting the correct chipbreaker and grade according to material, operation and machine rigidity yields tangible gains in productivity and surface finish, while the system approach—insert plus holder, shim/clamp and replacement screws—ensures repeatable clamping and quick replacement in production environments.

FAQ

Which materials are recommended for this insert?
The CCMT120408 T6215 insert is specified for machining rostfreier Stahl (stainless steels) under stable to lightly interrupted turning conditions; select the chipbreaker and cutting data to match workpiece alloy and rigidity.

What are the key dimensions and angles of the insert?
The insert has an inscribed circle of 12 mm, a thickness of 4.76 mm, a corner radius of 0.8 mm, a geometry angle of 80° and a relief angle of 7°, matching common ISO turning holder requirements.

How is compatibility with a holder determined?
Compatibility depends on the insert form, relief angle, tolerance class, clamping method, size and thickness; ensure the holder accepts the CCMT120408 format and the 4.76 mm plate thickness for secure clamping.

What performance can be expected from the T6215 grade?
Grade T6215 combines a wear‑resistant CVD coating with a carbide substrate to provide consistent edge life and good abrasion resistance when turning stainless steels, supporting longer tool life and stable process windows.

How is the insert clamped and secured in the assembly?
The insert uses a cylindrical hole with a single-sided countersink (40°–60°) for positive positioning; a compatible holder with the correct shim/clamp and replacement screws completes the system for repeatable clamping.
