CNMG 120402 T6215 turning insert — Tungaloy, CVD-coated carbide, 0.2 mm radius

CNMG120402 T6215 is an ISO-format indexable insert designed for turning applications, optimised for stainless steels under stable to lightly interrupted cutting conditions.

• CVD-coated carbide for wear resistance
• 80° rhombic geometry for versatile turning
• 0.2 mm corner radius for fine finishing
• Double-sided with cylindrical hole for secure clamping

Increased productivity through longer tool life

The CNMG120402 insert combines a CVD coating with a wear-resistant carbide substrate, providing a measurable increase in service life compared with uncoated grades. The coating reduces flank and crater wear, which translates into fewer indexings and less downtime. This results in higher process efficiency and a lower cost per component when machining medium-hard and stainless materials. The design supports stable cutting conditions, so the primary benefit is sustained cutting performance with predictable maintenance intervals.

Consistent surface quality and chip control for stainless steels

The 80° rhombic geometry and the double-sided chipbreaker are tuned to promote controlled chip formation when machining stainless steels, where work hardening and built-up edge are common challenges. The modest 0.2 mm corner radius enables fine finishing passes, producing improved surface finishes while maintaining edge strength. As a result, the insert enables reliable dimensional control and repeatable component quality, especially in serial production and precision-turning tasks where consistency matters.

Simple integration and secure clamping for workshop use

Compatibility with standard ISO holders is assured through the insert’s form, clearance angle, tolerance class, fastening method, size and thickness; the cylindrical hole supports positive location and repeatable clamping. The 4.76 mm thickness and standard 12 mm size ensure robust seating in common turning toolblocks, while the 0° relief angle reduces the risk of interference on profile work. The design therefore eases tool changeover, shortens setup time and contributes to a smoother production flow — particularly valuable in mixed-batch or tool-changing workplaces.

For procurement and application support, contact Metav Werkzeuge for supply and tailored advice — Metav Werkzeuge can confirm compatibility with existing holders and recommend cutting data for specific stainless steel grades.
