SNMG120408 T6215 indexable turning insert — CVD-coated carbide, 0.8 mm radius (Tungaloy)

A SNMG120408 T6215 indexable turning insert engineered for external and internal turning operations, optimised for machining stainless steels under stable to lightly interrupted conditions.

• ISO-standard SNMG insert
• CVD-coated carbide grade T6215
• Double-sided with cylindrical hole
• 0.8 mm corner radius, 90° geometry

Consistent performance for stainless-steel turning

The insert offers CVD-coated carbide in the T6215 grade, chosen for wear resistance when machining stainless steels. The combination of coating and substrate reduces adhesion and edge wear, which results in a more predictable tool life under steady cutting conditions. For production environments, this translates into fewer interruptions for insert changes and a stable surface finish. The design supports common turning tasks — facing, longitudinal turning and light profiling — where process stability is a priority.

Secure seating and simple compatibility with ISO holders

Built to the ISO SNMG120408 form, the geometry and the cylindrical hole ensure reliable clamping in conventional indexable holders or boring bars. The square plate form and standard thickness mean interchangeability across ISO-compliant tool systems; match the insert to the holder by form, relief angle, tolerance class, fastening method, size and thickness. This clarity in matching minimises setup time and supports consistent machining parameters across multiple machines.

Geometry and edge control for repeatable results

A 0.8 mm corner radius and a 90° plate geometry combine to deliver controlled cutting edge strength and predictable chip formation. The double-sided construction doubles the number of usable edges per insert, improving cost-efficiency in volume production. The medium-sized nose radius balances edge strength with the ability to maintain tighter tolerances on turned features, making the insert suitable for series parts where dimensional consistency matters.

Productivity and material range

While primarily specified for stainless steels, the grade and geometry provide flexibility for adjacent applications where similar material behaviour is encountered. The insert's construction supports steady cutting speeds and contributes to improved cycle times when used within recommended parameters. Selecting an appropriate chipbreaker and the correct grade ensures efficient swarf control and reduced risk of built-up edge during long runs.
