CNMG 120408 T6215 CNMG indexable turning insert — Tungaloy, CVD-coated carbide, 80°

CNMG120408 T6215 is an ISO-format indexable turning insert designed for external and internal turning, optimised for rostfreier Stahl under stable to lightly interrupted cutting conditions

• CVD-coated T6215 for stainless steel machining
• ISO CNMG120408 rhombic indexable insert
• 80° cutting angle with 0° relief
• Double-sided chipbreaker, cylindrical hole

Consistent cutting performance for stainless-steel turning

The insert combines a CVD-coated surface with a wear-resistant T6215 carbide substrate to extend tool life during continuous operations. This surface treatment reduces adhesive wear and maintains edge stability, which results in fewer tool changes and more predictable cycle times. For shops that value repeatability, the ISO CNMG120408 geometry offers a standardised form factor that simplifies tool inventory and holder selection while supporting stable chip evacuation.

Productivity gains through geometry and chip control

With an 80° cutting angle and a 0° relief, the rhombic geometry delivers a balance between strength and accessibility for both external and internal features. The integrated double-sided chipbreaker is optimised for common stainless-steel feeds, producing short, manageable chips that protect the workpiece surface and reduce downtime caused by chip entanglement. The combination of edge preparation and chip control yields measurable productivity improvements and lower rework rates.

Mounting, compatibility and system considerations

The insert features a cylindrical hole for secure fastening and a standardised size of 12 mm, allowing use with a wide range of ISO-compatible holders and boring bars. Compatibility depends on form, relief angle, tolerance class, fastening method, size and thickness; therefore, selecting a matching holder and clamping kit is essential for achieving the advertised stability. Where holder rigidity is high, the robust carbide substrate and coating provide the most benefit, particularly when machining rostfreier Stahl.

Application guidance and advantages for production

This grade is intended for turning applications where stable or lightly interrupted cuts are expected; it is especially suited to finish and light roughing operations in rostfreier Stahl. The tool’s design emphasises predictable wear behaviour and reliable surface quality rather than aggressive roughing removal rates. For engineers aiming to reduce variability in batch production, the insert’s combination of geometry and coating supports consistent tolerances and repeatable surface finishes.
