DNMG150408 T6215 DNMG — Turning insert for stainless steel by Tungaloy

DNMG150408 T6215 is an ISO-standard rhombic turning insert designed for general external and internal turning of stainless steels under stable to lightly interrupted cutting conditions

• CVD-coated carbide for high wear resistance
• Rhombic 55° geometry for versatile turning
• Double-sided chipbreaker for controlled chips
• 0.8 mm corner radius for stronger cutting edges

High wear resistance for consistent stainless-steel turning

The CVD-coated carbide grade delivers elevated wear resistance and thermal stability specifically tuned for machining stainless steel in consistent setups. The coating reduces flank and crater wear under continuous cutting, so the insert maintains dimensional stability over longer tool life. Select the appropriate chipbreaker and grade based on workpiece material and the rigidity of the setup to achieve reproducible results and minimise unplanned stops.

Geometry that supports repeatable surface quality and tool life

A 55° rhombic form with a 0° clearance and a 0.8 mm radius concentrates cutting forces into a stable edge geometry. The thicker body (4.76 mm) and the cylindrical hole secure the insert in the pocket and reduce vibration transmission, improving surface finish and extending edge life. These design choices improve resistance to chipping while offering versatility for both external and internal turning operations.

Controlled chip formation and economical operation

The double-sided chipbreaker promotes predictable chip formation and evacuation, which eases coolant and chip-management demands on the machine. Using a two-sided insert effectively doubles the available cutting edges before indexing is required, supporting economical operation without compromising process stability. The combination of chip control and the CVD coating helps to reduce downtime and tooling cost per part in production runs.

ISO compatibility and straightforward system integration

As part of the ISO insert family, this item integrates into standard toolholder systems where compatibility is defined by shape, clearance, tolerance class, attachment style, size and thickness. Typical system components include the ISO insert, a matching external holder or boring bar, a clamping set, and replacement screws. For complex applications or transition to new materials, technical advice is available to confirm holder selection and clamping torque to maintain secure seating and consistent cutting results. If there is uncertainty about process parameters or holder matching, the technical team can provide guidance or specific recommendations via email or phone.
