Reliable turning performance for stainless steels is achieved through the combination of a CVD-coated carbide grade and an 80° rhombic geometry with a 1.6 mm corner radius; order this insert via Metav Werkzeuge or consult our specialists for application advice.

CNMG120416 T6215 ISO turning insert — rhombic 80° for turning, Tungaloy

A CNMG120416 T6215 indexable insert designed for ISO-compliant external and internal turning, optimised for stable to lightly interrupted machining of stainless steels

• CVD-coated carbide T6215 for wear resistance
• 80° rhombic geometry for versatile turning
• 1.6 mm corner radius for robust edge strength
• Double-sided chipbreaker for consistent chip control
• Cylindrical hole for secure mounting

Improve process stability when machining stainless steels

The insert's CVD-coated carbide grade provides elevated wear resistance and thermal stability during continuous turning operations, which translates into fewer interruptions and more predictable tool life. The moderate 1.6 mm corner radius reduces edge chipping risk during heavier engagement yet maintains a reliable profile for achieving consistent surface finish. Used in the correct cutting window, this geometry supports stable cutting and helps maintain dimensional tolerance in serial production.

Simplify tooling management with ISO compatibility

As an ISO-compliant CNMG form, the insert fits a wide range of standard holders and boring bars; compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness. The 80° rhombic geometry balances strength and accessibility for shoulders and profiles, while the cylindrical hole and standard thickness simplify clamping and replacement routines. The double-sided design and standardised dimensions reduce inventory complexity and enable rapid indexation during changeovers, contributing directly to improved shop-floor efficiency.

Balance cutting performance and reproducibility

The T6215 grade offers a wear-resistant coating tailored to the demands of stainless steel turning under stable to slightly interrupted conditions. Combined with a double-sided chipbreaker, the insert promotes controlled chip formation, reducing rework and machine downtime. This focus on reproducible cutting behaviour supports a favourable cost-per-part ratio by extending edge life and lowering the frequency of insert changes in medium- to high-volume runs.

Practical selection and application guidance

Selection of the correct chipbreaker and holder stiffness is essential: choose a breaker and grade that match the workpiece alloy and the expected interruption severity. The insert's geometry and coating are optimised for machining oxidising and work‑hardening alloys, but process variables such as feed, depth of cut and coolant strategy will determine the final cutting window. When paired with a suitably rigid toolholder and correct clamping, this insert offers a straightforward route to increased cycle stability and consistent surface quality in production turning.
