DNMG150412 T6215 DNMG Turning Insert — CVD‑coated carbide, 55° rhombic (Tungaloy)

The DNMG150412 T6215 is an ISO‑standard rhombic turning insert for external and internal turning, optimised for stainless steels under stable to lightly interrupted cutting conditions

• CVD-coated carbide for wear resistance
• 55° rhombic form, positive geometry
• Double-sided chipbreaker for stable chips
• Cylindrical hole, 4.76 mm thickness, 1.2 mm radius

Consistent performance in stainless steel turning

The CVD‑coated carbide grade T6215 combines a wear‑resistant coating with a robust substrate, delivering stable tool life when machining stainless steels. The CVD process deposits hard ceramic layers that reduce flank wear and improve resistance to built‑up edge and adhesion — common issues when turning austenitic stainless grades. For production runs where repeatability and predictable insert life matter, this grade reduces unplanned tool changes and supports higher uptime.

Improved chip control and productivity

A double‑sided chipbreaker on a 55° rhombic insert enhances chip formation and evacuation for a wide range of cutting conditions. The positive geometry of the rhombic shape lowers cutting forces and heat generation, which in turn reduces power consumption and spindle load. Stable chip control decreases secondary operations for chip clean‑up, meaning fewer interruptions and a smoother, more productive turning cycle for bars and components.

ISO compatibility and system guidance

As an ISO‑standard turning insert, compatibility with the toolholder depends on form, clearance angle, tolerance class, fastening method, size and thickness. Confirm holder match by checking the holder pocket for DNMG‑type inserts and the clamping method for a cylindrical centre hole. Choosing the correct holder and clamping set ensures secure seating, repeatable positioning and the intended cutting geometry during indexing.

Design features that support economic machining

Key dimensions such as the 1.2 mm corner radius, 4.76 mm thickness and the cylindrical hole influence edge strength, stability and clamping reliability. A larger corner radius increases nose strength for heavier cuts, while the given thickness provides rigidity for extended tool life. Specified for turning under stable to lightly interrupted conditions, this insert offers a balance between edge durability and finish quality, contributing to lower overall machining costs through fewer tool changes and consistent workpiece tolerances.

FAQ

What materials is this insert suited to machine?
The DNMG150412 T6215 insert is optimised for machining stainless steels, offering wear resistance and reduced tendency to form built‑up edge in common stainless grades.

How does the double‑sided chipbreaker benefit production?
A double‑sided chipbreaker provides repeatable chip control and allows indexing of the insert to use both cutting edges, increasing productivity and reducing tooling costs for the turning process.

Which holders are compatible with DNMG inserts?
Compatibility requires a holder designed for DNMG‑type inserts; check form, clearance angle, tolerance class, fastening method, size and thickness to ensure proper seating and clamping of the insert.

How does the 1.2 mm corner radius affect cutting?
The 1.2 mm corner radius improves nose strength and tool life for moderate depths of cut, balancing robustness with surface finish quality in turned components.
