SNMG120404 T6215 turning insert by Tungaloy

The SNMG120404 T6215 is an ISO-standard indexable insert engineered for precision turning of stainless steels in stable to lightly interrupted cuts.

• CVD-coated carbide grade T6215
• Optimised for stainless steel turning
• Double-sided with cylindrical hole
• 0.4 mm corner radius, 90° geometry

Longer tool life through advanced coating and substrate

The proven CVD-coated carbide substrate in grade T6215 provides a durable surface finish and enhanced wear resistance when machining rostfreier Stahl (stainless steels). Chemical vapour deposition (CVD) applies hard ceramic layers that protect the carbide substrate against diffusion wear and built-up edge formation; this translates into fewer tool changes and more productive machining cycles. For shops moving between batch sizes, the coating delivers measurable economy by preserving cutting-edge geometry over longer runtimes.

Stable cut and predictable chip control for turning operations

The insert’s double-sided design and integrated chipbreaker provide two cutting edges per index, improving tool utilisation while maintaining reliable chip formation. The 0.4 mm corner radius and 90° included angle support robust engagement in external and internal turning, lowering vibration risk and improving surface finish. Operators unfamiliar with chipbreaker behaviour benefit from the consistent chip patterns this geometry produces, which simplifies coolant and speed/feed optimisation.

Straightforward integration into ISO tooling systems

Manufactured to ISO dimensions, the insert matches holders according to form, clearance angle, tolerance class, fastening and thickness, ensuring mechanical compatibility. The cylindrical hole facilitates stable clamping and easy indexing, while the nominal 4.76 mm plate thickness and 12 mm inscribed circle conform to widely used toolholder families. Using standardised parts reduces setup time and simplifies tool inventory management in mixed-production environments.

Application-focused benefits for stainless steel machining

Designed specifically for turning, the grade’s wear resistance and chip control make it suitable for continuous and lightly interrupted cuts on stainless steels. The 0° clearance geometry minimises radial interference in constrained setups and helps preserve edge strength when encountering soft, adhesive materials like certain austenitic alloys. Selection of the appropriate chipbreaker and stable machining conditions will yield the best combination of surface quality and tool life.
