DCMT 11T304 T6215 turning insert – Tungaloy (rhombic, 55°)

The DCMT11T304 T6215 is a CVD-coated carbide insert designed for general turning, offering wear resistance and predictable chip control for external and internal turning operations.

• CVD-coated carbide grade T6215
• 55° rhombic geometry for versatile turning
• 0.4 mm corner radius for fine finishing
• Cylindrical hole with one-sided countersink

Maximise uptime with a wear-resistant coating

The CVD-coated T6215 grade delivers enhanced wear resistance and consistent performance in machining stainless steels under stable to lightly interrupted conditions. The chemical vapour deposition layer reduces flank wear and maintains a stable cutting edge, which means longer periods between indexings and fewer unexpected tool changes. For production environments where process stability and repeatability are priorities, this coating supports a higher effective tool life and contributes to predictable cycle times.

Geometry engineered for reliable surface quality

A 55° rhombic geometry combined with a 0.4 mm corner radius gives a balance between strength and finishing capability. The rhombic form provides multiple effective cutting corners and good access in both external and internal turning, while the modest corner radius helps achieve the required surface integrity without excess cutting forces. The one-sided chipbreaker is optimised for controlled swarf formation, reducing the risk of built-up edge and improving surface finish on machined parts.

Designed for compatibility and easy handling

The insert fits ISO-standard turning systems and is best used with a matching external holder or boring bar chosen for form, clearance angle and tolerance class. The cylindrical hole with a one-sided countersink (40°–60°) enables secure clamping and precise seating, simplifying index changes and reducing setup time. With a thickness of 3.97 mm and nominal size 11, the insert integrates into common toolholders and replacement screw sets, supporting efficient workshop workflows and minimal tool stock complexity.
