CNMG 090412 T6215 indexable insert for turning — Tungaloy, CVD‑coated carbide, double‑sided chipbreaker

The CNMG090412 T6215 is an ISO‑format indexable insert designed for turning applications, offering a wear‑resistant CVD coating and a chip control geometry suited to rostfreier Stahl.

• CVD‑coated carbide grade T6215
• Suitable for rostfreier Stahl turning
• Double‑sided chipbreaker for stable chips
• ISO CNMG 090412, 80° rhombic geometry

High‑wear resistance for stable production

The CVD‑coated carbide T6215 grade delivers elevated wear resistance under stable to mildly interrupted cutting conditions, which translates into fewer insert changes and longer tool life. This hardcoating deposits a uniform ceramic layer that reduces flank wear and supports consistent cutting temperatures; the result is improved process predictability and reduced unplanned downtime. For production environments where cycle time and repeatability matter, the combination of coating and substrate offers measurable productivity gains.

Clear compatibility and secure mounting for fast setup

Built to the ISO CNMG 090412 format, the insert's 80° rhombic geometry and 4.76 mm thickness ensure broad compatibility with standard external holders and boring bars, while the presence of a cylindrical centre hole enables reliable clamping. Compatibility is determined by holder form, clearance angle and tolerance class; compatibility checks avoid costly adaptations and shorten setup time. The standardised shape simplifies spare‑part management and inventory planning for machining shops.

Predictable chips and improved surface finish

The double‑sided chipbreaker is engineered to produce controlled chip formation when machining rostfreier Stahl, supporting both continuous and slightly interrupted cuts. Controlled chip flow reduces rework risk and protects workpiece surfaces, contributing to superior surface quality and more consistent dimensional stability. A corner radius of 1.2 mm balances edge strength and finish, offering a compromise between robust cutting and the ability to achieve fine finishes in typical turning tasks.

Economical handling and application guidance

Being indexable and double‑sided, the insert maximises usable cutting edges and reduces cost per cutting edge compared with brazed tools, supporting more economical tool management. The geometry and coating are optimised for turning operations and integrate into conventional ISO tool systems without special adaptations. For technical selection or matching to a specific holder system, Metav Werkzeuge provides application guidance and can advise on the most suitable chipbreaker and grade pairing for a given machining scenario.

FAQ

What applications suit this insert best?
This insert is intended for external and internal turning; the CNMG090412 T6215 is especially suited to machining rostfreier Stahl under stable to slightly interrupted conditions.

What material is the cutting edge made from?
The CNMG090412 T6215 features a CVD‑coated carbide substrate; the coating enhances wear resistance and supports longer tool life.

How is the insert secured in the holder?
The insert has a cylindrical centre hole and is clamped in place with the appropriate clamp and screw system compatible with ISO CNMG inserts.

What effect does the corner radius have on machining?
The 1.2 mm corner radius increases edge strength for more robust cutting while still allowing good surface quality, making it a balanced choice for many turning operations.

Can the chip shape be controlled for rostfreier Stahl?
Yes, the double‑sided chipbreaker is designed to produce predictable chips when machining rostfreier Stahl, improving process stability and surface finish.
