DCMT 11T312 T6215 turning insert, 55° rhombic — Tungaloy

DCMT11T312 T6215 is an ISO‑standard turning insert optimised for stable to slightly interrupted machining of stainless steels, offering a wear‑resistant CVD coating and geometry suitable for both external and internal turning.

• CVD-coated carbide for stainless steel machining
• 55° rhombic shape for versatile turning
• 1.2 mm corner radius for consistent edge strength
• Cylindrical hole with single-sided countersink

High‑performance turning with fewer interruptions

The CVD‑coated carbide grade T6215 delivers elevated wear resistance and stable chip formation when machining stainless steel, which helps to extend cutting edge life and maintain component quality. The coating and substrate combination reduce built‑up edge and improve heat resistance under continuous cutting, meaning fewer insert changes and longer productive runs. For best results, select the chipbreaker and grade that match the workpiece material and cutting conditions to achieve a consistent surface finish and minimal rework.

Easy integration into ISO tool systems for secure clamping

Designed as an ISO‑standard plate, the insert fits into compatible holders when shape, relief angle, tolerance class, fixing method, size and thickness are matched correctly. The 55° rhombic form and 7° relief support a range of turning operations, while the cylindrical hole with one‑sided countersink (40°–60°) ensures positive seating and secure clamping, reducing vibration and enhancing repeatable part accuracy. The modest 3.97 mm thickness contributes to stability in both external and internal setups.

Practical gains for production efficiency

A 1.2 mm corner radius provides a balance between edge robustness and cutting forces, promoting reliable tool life and consistent component tolerances. Using this insert within a complete system — insert, suitable external holder or boring bar, shim/clamping set and replacement screws — streamlines changeovers and supports predictable machining cycles. The geometry and coating support improved productivity by reducing downtime for tool changes and by delivering a repeatable surface quality across batches.

FAQ

Which materials is this insert best suited to machine?
The DCMT11T312 T6215 insert from Tungaloy is optimised for stainless steel machining under stable to lightly interrupted conditions, providing improved wear resistance and chip control.

What does the 55° rhombic geometry mean for turning tasks?
A 55° rhombic shape offers versatility for both external and internal turning, enabling balanced cutting forces and good edge support for general turning operations.

How does the T6215 CVD coating benefit production?
The T6215 CVD coating increases heat and wear resistance, which extends tool life and helps maintain surface finish during longer production runs with stainless steel workpieces.

What should be checked for correct insert compatibility with holders?
Compatibility depends on plate form, relief angle, tolerance class, fixing method, size and thickness; ensure the holder matches the ISO designation and the insert’s 3.97 mm thickness and hole style.

Is this insert suitable for interrupted cuts?
The grade and geometry are intended for stable to slightly interrupted cutting; for heavily interrupted conditions specialised grades or geometries should be considered.
