CCMT 120412 T6215 turning insert (Tungaloy) — ISO-format CVD-coated carbide

The CCMT120412 T6215 is an ISO-format indexable turning insert designed for stable to slightly interrupted turning of stainless steels, offering robust wear resistance and predictable tool life.

• ISO-format rhombic insert, 12 mm
• CVD-coated carbide grade T6215
• Single-sided chipbreaker, with hole and countersink
• 7° relief angle for secure clamping

Durable coating for prolonged stainless-steel turning

The CCMT120412 is manufactured from CVD-coated carbide, a combination that delivers enhanced wear resistance and thermal stability during high-friction turning operations. The CVD coating forms a hard, wear-resistant surface that slows flank and crater wear, enabling longer cutting intervals and more consistent component quality. For workshops aiming to reduce tooling changes and achieve repeatable part tolerances, this coating-grade pairing provides measurable productivity gains and predictable tool-life behaviour.

ISO conformity and geometry for fast integration into tool systems

Designed to ISO geometry, the insert’s rhombic form and 12 mm designation permit straightforward selection of compatible holders. Key dimensions such as the 1.2 mm corner radius, 4.76 mm plate thickness and the 80° included angle influence cutting forces and surface finish; the 7° relief angle supports reliable clamping and clearance. The insert features a cylindrical hole with a one-sided countersink (40°–60°) for standard screw fixation. Because holder compatibility depends on shape, clearance angle, tolerance class, mounting style, size and thickness, systems integration is simplified when these parameters are matched.

Stable chip control and consistent surface quality

Equipped with a single-sided chipbreaker, the insert supports efficient chip formation in turning operations of challenging materials such as stainless steel, helping to avoid built-up edge and to maintain surface integrity. In stable to lightly interrupted cuts the geometry promotes uniform chip evacuation and consistent finishes, reducing rework and downtime. For process optimisation, Metav Werkzeuge’s technical advisors can supply cutting data, recommend feeds and speeds for the grade T6215, and suggest suitable holder geometries to maximise productivity.

FAQ

What materials is this insert designed for?
The CCMT120412 T6215 insert is optimised for turning stainless steel under stable to slightly interrupted cutting conditions, using its CVD-coated carbide grade for enhanced wear resistance.

How does the chipbreaker affect machining?
The single-sided chipbreaker on the T6215 grade promotes controlled chip formation and evacuation during turning, improving surface finish and reducing the risk of built-up edge.

Which holder features must be matched for correct fit?
Holder selection requires matching the insert’s rhombic form, clearance (7°) and thickness (4.76 mm), as well as the plate size (12 mm) and fixing method compatible with the cylindrical hole and countersink.

Is this insert suitable for interrupted cuts?
The insert is suitable for stable to slightly interrupted turning; for heavy interruptions or unstable setups, a different geometry or a more robust grade may be recommended.

What information is available to set cutting parameters?
Cutting data for the CCMT120412 T6215 insert are available from Metav Werkzeuge’s technical team, who can advise on feed, speed and coolant strategy for the intended application.
