CNMG120416 T6215 ISO turning insert for turning applications — Tungaloy

A CNMG120416 T6215 indexable turning insert designed for machining rostfreier Stahl under stable to slightly interrupted cutting conditions, supplied in ISO‑standard CNMG geometry

• CVD-coated carbide grade T6215
• 80° rhombic insert geometry
• Double-sided chipbreaker, with cylindrical hole
• Optimised for rostfreier Stahl turning

High wear resistance and predictable performance for rostfreier Stahl machining

The CVD‑coated carbide grade T6215 delivers a balance of wear resistance and toughness, making it suitable for continuous and slightly intermittent turning of rostfreier Stahl. The coating reduces flank wear and helps maintain cutting edge integrity, while the substrate provides shock tolerance during modest interruptions. In practice, this means longer in‑process life, fewer index changes and more predictable batch output, which supports efficient production planning and reduces unplanned downtime.

Secure fit and standardised compatibility to simplify tooling selection

Produced to ISO dimensions and featuring CNMG rhombic geometry with an 80° included angle, the insert is compatible with a wide range of external holders and boring bars when the holder matches form, clearance angle, tolerance class, fastening style, size and thickness. The insert's cylindrical hole and defined 4.76 mm thickness permit reliable clamping with standard shims and screws, ensuring repeatable concentricity and stable cutting conditions. Clear guidance on holder selection minimises trial‑and‑error and contributes to reproducible part quality.

Cost‑effective system performance and recommended applications

With a 1.6 mm corner radius and double‑sided chipbreaker, this indexable insert is aimed at both external and internal turning tasks where surface finish and edge life matter. The rhombic shape allows economical use of both major corners, improving cost per cutting edge. Typical use cases include general turning of shafts and rings in rostfreier Stahl, light profiling and stepping operations. The insert integrates into a standard system setup comprising a matching external holder or bar, a locating shim or clamp set and the appropriate replacement screws, thereby simplifying inventory management while supporting productive machining cycles.

FAQ

What materials is this insert suited for?
The CNMG120416 T6215 insert is optimised for machining rostfreier Stahl and performs well in stable to lightly interrupted turning operations.

How does the T6215 coating benefit tool life?
The CVD coating on the T6215 grade reduces flank wear and improves resistance to adhesive and abrasive wear, which extends the service interval of the insert during continuous rostfreier Stahl turning.

Can the insert be used in internal and external turning?
Yes, the rhombic CNMG geometry and double‑sided design make the insert suitable for both internal and external turning when paired with the appropriate holder and clamping components.

How is compatibility with a toolholder determined?
Compatibility depends on matching geometry, clearance angle, tolerance class, fastening arrangement, size and thickness; these parameters should align with the ISO‑standard dimensions of the insert.

What system components are required to mount the insert?
A compatible external holder or boring bar, a locating shim or clamp set and the correct replacement screws are required to secure the insert for machining.
