CNMG 120412 T6215 Turning Insert (ISO CNMG) – CVD-coated carbide, 80° (Tungaloy)

The CNMG 120412 T6215 is an ISO-indexed rhombic turning insert designed for stable to slightly interrupted machining of stainless steels in external and internal turning.

• CVD-coated carbide T6215
• Optimised for stainless-steel turning
• 80° rhombic CNMG geometry
• Double-sided chipbreaker with cylindrical hole

Productive, wear-resistant grade for stainless-steel turning

The CVD-coated T6215 grade delivers high wear resistance and consistent edge life under stable to lightly interrupted cutting conditions, making it a solid choice for rostfreier Stahl machining where surface finish and tool life matter. The coating reduces built-up edge and thermal wear; the carbide substrate beneath the coating preserves edge stability. As a result, cycle times are often reduced and insertion intervals extended, contributing to a measurable improvement in process efficiency and part consistency.

Geometry and mounting that support secure, precise cutting

The rhombic CNMG geometry with an 80° included angle and a 0° relief provides a reliable cutting profile for a range of turning tasks. The 1.2 mm corner radius offers a balance between edge strength and attainable surface finish, while the cylindrical hole ensures positive locating and clamping in ISO-compatible holders. Where holder compatibility is concerned, matching of form, relief angle, tolerance class, fastening method, size and thickness is essential; compatibility can be verified against ISO specifications or by consulting Metav Werkzeuge for holder recommendations.

Chip control, handling and operational benefit

A double-sided chipbreaker on both faces improves chip formation in stainless-steel applications, lowering the risk of long, stringy chips and enabling smoother machining cycles. The insert’s ISO indexing and reversible faces allow for economical edge changes and reduced tooling costs per cutting edge. For shops seeking predictable repeatability, this design reduces unplanned downtime and simplifies inventory management, while the CVD layer helps maintain cutting-edge geometry over extended runs.

FAQ

What materials is this insert suitable for?
The CNMG 120412 T6215 insert is formulated for machining stainless steels (rostfreier Stahl) under stable to slightly interrupted conditions; the CVD-coated carbide provides wear resistance for such materials.

How does the T6215 grade perform compared with general-purpose grades?
T6215 is a wear-resistant CVD-coated grade that offers longer edge life on stainless steels compared with many uncoated or general-purpose grades, improving productivity and surface quality in turning operations.

What does the CNMG120412 designation indicate?
The CNMG120412 designation refers to the CNMG geometry, 12 mm size and 1.2 mm corner radius configuration; it follows ISO-indexed insert nomenclature for geometry and dimensions.

Is the insert reversible and how many faces are usable before disposal?
This insert features chipbreakers on both faces and is ISO-indexed; faces can be indexed per the holder and system in use, enabling multiple cutting edges to be used before replacement—check the chosen holder system for exact indexing options.

What mounting and clamping features are required?
The insert has a cylindrical hole for positive location and requires an ISO-compatible external holder or boring bar that matches form, relief angle, tolerance class, fastening method, size and thickness to ensure secure clamping and repeatable results.
