SNMG 120412 T6215 Turning Insert by Tungaloy — CVD-coated carbide, 90°

SNMG120412 T6215 is an ISO‑standard turning indexable insert for external and internal turning, designed for stable to lightly interrupted machining of stainless steels

• CVD-coated carbide grade T6215
• ISO SNMG120412 indexable shape
• Suitable for stainless steels
• Double-sided chipbreaker with hole

Extended tool life through wear-resistant coating and grade

The CVD‑coated carbide composition and the selected T6215 grade combine to deliver improved wear resistance under typical turning conditions for stainless steels. The coating reduces flank and crater wear during extended cuts, which leads to longer intervals between tool changes and lower tooling costs per component. As a consequence of the hard coating and substrate pairing, the insert sustains cutting-edge integrity in stable setups, supporting predictable production runs and helping to maintain consistent part quality over time.

Reliable chip control and surface quality for demanding materials

The engineered double‑sided chipbreaker promotes repeatable chip formation and evacuation when machining stainless grades that tend to form continuous chips. Controlled chip flow reduces the risk of entanglement and secondary finishing, while the insert geometry contributes to a consistent surface finish on turned components. Where surface integrity is critical, the combination of the chip control feature and the CVD-coated surface assists in achieving controlled temperatures at the cutting zone and minimises chatter-related marks.

ISO compatibility simplifies tool selection and integration

Manufactured to ISO specifications for SNMG inserts, the design ensures compatibility with a wide range of standard external holders and boring bars; compatibility depends on shape, relief angle, tolerance class, clamping method, size and thickness. The presence of a cylindrical central hole and the standard square form facilitate secure clamping and straightforward replacement in toolholders, enabling rapid set‑ups and predictable positioning for repeatable geometry and tool offsets.

Application guidance: where this insert performs best

The insert is suited to both external and internal turning operations under stable to lightly interrupted cutting conditions. For optimal results, pair the grade and chipbreaker with a holder and clamping system matched to the workpiece rigidity and spindle power. The 90° main cutting edge orientation and the nominal corner radius support general turning profiles; selecting appropriate cutting data for stainless steels will further extend tool life and improve productivity.
