DNMG 150404 T6215 indexable insert for turning — Tungaloy

The DNMG150404 T6215 Tungaloy insert is an ISO-standard, rhombic turning insert designed for external and internal machining of stainless steels under stable to lightly interrupted cutting conditions.

• CVD-coated carbide T6215 for stainless steels
• Rhombic 55° insert with cylindrical hole
• Double-sided chipbreaker for cost efficiency
• 0.4 mm corner radius, 4.76 mm thickness

Consistent cutting performance for stainless steels

The CVD-coated carbide grade T6215 is formulated for wear resistance when machining stainless steels, offering a stable cutting edge under continuous and slightly interrupted cuts. The coating reduces flank wear and extends edge life, which translates into longer uninterrupted production runs and fewer tool changes. The insert’s geometry promotes predictable chip formation and reduced built-up edge, so process windows remain stable even when feed and speed are varied for optimisation.

Compatibility and secure clamping for reliable setup

Machining reliability starts with correct seating and clamping. The ISO-standard rhombic shape with a 55° lead angle and a cylindrical hole enables simple, repeatable positioning in standard holders; compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness. The through-hole supports positive clamping and straightforward replacement with existing toolholders, reducing setup time and ensuring secure clamping that maintains repeatability over batch production.

Productivity gains from geometry and edge design

A double-sided chipbreaker doubles the available cutting edges, improving cost efficiency per insert and reducing changeover frequency. The 0.4 mm nose radius supports fine finish work and light profiling, while the 4.76 mm thickness provides sufficient body stiffness for stable performance at moderate cutting parameters. Together, these features help to achieve consistent surface finishes and reliable chip control, so cycle times and downstream rework can be reduced.

Choosing the right grade and chip control for process stability

Selecting the correct chipbreaker and grade for the workpiece and machining strategy is essential; the chip control built into this insert supports effective evacuation and lowers the risk of edge damage. The robust edge preparation of the grade contributes to process stability and longer tool life, especially when paired with an appropriate holder and clamping kit. For specialised applications or interrupted cuts, matching holder rigidity and cutting data to the component and machine dynamics is advised. If additional technical data is required, the Metav Werkzeuge team can provide cutting parameter recommendations and compatibility checks.
