CNMG 120412 T6215 Wendeplatten - Tungaloy

Take advantage of the combination of a CVD‑coated carbide grade (T6215), a 1.2 mm corner radius and an 80° rhombic geometry to achieve stable turning of stainless steel with reliable chip control and extended tool life; order directly via Metav Werkzeuge or consult the team for application support.

CNMG 120412 T6215 ISO rhombic turning insert — CVD‑coated carbide, 1.2 mm radius (Tungaloy)

CNMG 120412 T6215 is an ISO‑standard rhombic insert designed for external and internal turning applications where wear resistance and consistent surface quality are required

• ISO rhombic insert CNMG 120412
• CVD-coated carbide grade T6215
• 1.2 mm corner radius, 80° geometry
• Double-sided chipbreaker, cylindrical hole

Consistent wear resistance for stainless steel turning

The CVD‑coated carbide composition in T6215 delivers high wear resistance for turning stainless steel under stable to lightly interrupted conditions. The chemical vapour deposition layer improves thermal stability at the cutting edge, which reduces flank wear and helps maintain a predictable cutting life. This results in more consistent surface finish and fewer tool changes, directly contributing to lower process costs and less machine downtime. The coating’s role is to protect the substrate during higher temperatures commonly encountered when machining corrosion‑resistant alloys.

Geometry and chip control that secure process reliability

The rhombic 80° approach with a 1.2 mm corner radius and a double‑sided chipbreaker provides predictable chip formation and strength at the corner for semi‑finishing and finishing passes. The cylindrical hole and standard plate thickness (4.76 mm) enable secure clamping in compatible ISO holders; compatibility is determined by form, clearance angle, tolerance class, fastening, size and thickness. A properly matched chipbreaker and grade reduce vibration and support repeatable machining results, making the insert suitable where dimensional stability and surface integrity matter.

Integration into the turning system for efficient production

As an ISO turning insert, the CNMG format integrates into common external holders or boring bars together with the required shim and clamp set and replacement screws. The reversible, double‑sided design increases tool economy: when one edge is worn, indexing yields another usable edge without removal of the substrate. This system approach supports shorter setup times and simpler inventory management while supporting higher productivity and predictable performance in batch or serial production environments. Application guidance and grade selection for specific feeds and speeds are available to align cutting data with machine rigidity and workpiece material.

FAQ

What materials is this insert best suited for?
The CNMG 120412 T6215 insert is optimised for stainless steel and similar stainless materials thanks to its CVD coating and carbide substrate, providing wear resistance and thermal stability.

How does the T6215 grade affect tool life?
The T6215 CVD‑coated carbide extends tool life by improving heat resistance and protecting the cutting edge, so the insert maintains cutting performance longer under continuous or lightly interrupted cuts.

Is the insert reversible and economical for batch production?
Yes, the rhombic CNMG form is double‑sided with a chipbreaker on each face, allowing indexing to a fresh edge and reducing tooling costs across production runs.

Which holder characteristics must be checked for compatibility?
Compatibility with a holder is determined by the insert form, clearance angle, tolerance class, fastening method, plate size and thickness; these parameters ensure secure clamping and correct geometry during turning.

What system components are required to fit the insert?
A compatible external holder or boring bar, the appropriate shim/underlay, clamping set and replacement screws are the standard components for assembling the ISO insert system.
