CNMG 120412 T6215 — Indexable insert for turning by Tungaloy

The CNMG120412 T6215 is an ISO-format indexable insert designed for external and internal turning, optimised for rostfreier Stahl under stable to slightly interrupted cutting conditions

• CVD-coated carbide grade T6215
• Designed for rostfreier Stahl turning
• 80° rhombic geometry with cylindrical hole
• Double-sided chipbreaker for stable cutting

Durable CVD coating for extended edge life

The CVD-coated carbide composition, identified by grade T6215, provides a hard, wear-resistant surface that reduces flank wear during extended cuts. This coating is particularly suitable for rostfreier Stahl where built-up edge and adhesive wear can shorten tool life; the protective layer delays wear progression and permits longer uninterrupted machining, translating into fewer indexings and improved cost-efficiency per component. The effect of the coating is a more consistent finish and predictable tool-change intervals.

Geometry and form that improve process stability

The insert’s 80° rhombic geometry with a cylindrical hole ensures secure clamping and compatibility with a wide range of ISO holders. The 1.2 mm corner radius supports robust engagement in moderate depths of cut, while the rhombic shape offers a balance between strength and accessibility in external and internal operations. Compatibility is determined by form, clearance angle, tolerance class, clamping method, size and thickness, so selecting the correct holder and backlash settings is essential for repeatable accuracy and vibration suppression.

Chip control and productivity for turning applications

Equipped with a double-sided chipbreaker, the insert improves chip formation across varied feeds and cutting directions, reducing the risk of entanglement and stabilising cycle times. As an indexable insert with multiple usable edges, it allows cost-effective edge replacement without discarding the body. For shops aiming to increase throughput, this combination of chip control and reliable edge life supports higher material removal rates under stable conditions and contributes to predictable surface quality on finished parts.

FAQ

What materials is this insert suitable for?
The CNMG120412 T6215 insert is intended primarily for rostfreier Stahl; the T6215 grade and its CVD-coated carbide construction provide wear resistance suited to that material class.

How does the double-sided chipbreaker affect tool life?
The double-sided chipbreaker on this turning insert improves chip formation and evacuation, contributing to steadier cutting conditions and more consistent edge life across indexed positions.

Can this insert be used for internal turning as well as external turning?
Yes, the rhombic 80° geometry and the plate’s form make it suitable for both external and internal turning operations, provided a compatible holder and clamping arrangement are used.

Which parameters determine compatibility with a holder?
Compatibility for ISO-format inserts is governed by the insert form, clearance angle, tolerance class, clamping method, size and thickness; ensure these align between the CNMG120412 insert and the selected holder
