DCMT 11T308 T6215 DCMT11T308 indexable turning insert for turning — Tungaloy

The DCMT11T308 T6215 is an ISO‑standard rhomboid indexable insert designed for turning operations, optimised for machining stainless steels under stable to mildly interrupted cutting conditions.

• CVD‑coated carbide T6215 for wear resistance
• 55° rhomboid geometry for versatile turning
• 0.8 mm corner radius for finishing and light roughing
• Central hole with countersink for secure clamping

Consistent productivity through wear‑resistant grade and coating

The insert’s CVD‑coated carbide construction ensures sustained cutting performance when machining stainless steels, where heat and work‑hardening can otherwise shorten tool life. The T6215 grade is formulated to resist abrasive and adhesive wear under stable to slightly interrupted cuts, which means longer intervals between index changes and fewer unscheduled tool exchanges. This translates into measurable productivity gains and more consistent component quality when facing typical turning tasks.

Geometry engineered for precision and secure mounting

The 55° rhomboid geometry with a 0.8 mm corner radius provides a balanced profile for external and internal turning, offering a compromise between edge strength and surface finish. The single‑sided chipbreaker supports controlled chip formation for many stainless steel alloys, while the central hole with a cylindrical bore plus a one‑sided countersink (40°–60°) enables secure clamping in compatible holders. The modest 7° clearance angle and plate thickness 3.97 mm contribute to stable seating and repeatable tool positioning in ISO‑standard toolholders.

Material and coating advantages explained for reliable results

A CVD (chemical vapour deposition) coating forms a hard, thermally stable layer on the carbide substrate, improving resistance to oxidation and flank wear during elevated cutting temperatures. For stainless steel turning, this means less tendency for built‑up edge and improved surface integrity on the workpiece. The combination of grade and coating offers a practical solution where consistent edge retention is required, supporting a predictable machining cycle and reducing process variation.

System compatibility and recommended setup for turning applications

The insert forms part of an ISO plate system: the complete setup requires a matching external holder or boring bar, a supporting shim and clamping set, and the correct fastening screw. Compatibility is determined by shape, clearance angle, tolerance class, fastening method, size and thickness; selecting a holder that matches the DCMT11T308 geometry and the insert’s clamping style is essential for vibration control and repeatable performance. Opt for the chipbreaker and grade that suit the specific stainless steel grade and the stability of the machining setup to achieve the targeted balance of tool life and surface finish.
