SNMG120408 T6215 ISO turning insert by Tungaloy, CVD-coated carbide for stainless steel turning

The SNMG120408 T6215 is an ISO‑standard square turning insert designed for stable to slightly interrupted turning operations, especially suited to machining stainless steel.

• ISO standard SNMG geometry
• CVD-coated carbide grade T6215
• Double-sided chipbreaker, with cylindrical hole
• 0.8 mm corner radius, 4.76 mm thickness

Consistent wear resistance for longer tool life

The CVD‑coated carbide grade provides robust wear resistance under continuous and mildly interrupted cuts, reducing the frequency of tool changes and improving process stability. The CVD-coated carbide surface offers a hard, thermally resistant layer that delays flank wear and maintains cutting edge integrity when turning stainless steel. This leads to more predictable tool life and fewer unplanned stoppages, which is a clear advantage in serial production and contract machining environments.

Stable cutting geometry that simplifies setup

With an ISO‑standard SNMG form and a square, 12 mm insert size, the geometry ensures straightforward replacement and compatibility with a wide range of external holders and boring bars. The double‑sided chipbreaker permits economical indexing while controlling chip formation during external and internal turning. The insert’s cylindrical hole and standard tolerances support secure clamping and repeatable positioning, so set‑up time is reduced and process reproducibility is improved.

Precision details that support surface quality and productivity

The 0.8 mm corner radius and a relief angle of 0° provide a balance between edge strength and surface finish. The moderate radius helps maintain component integrity on stainless parts, lowering the tendency for built‑up edge formation when combined with the appropriate coolant and cutting data. The insert’s 4.76 mm thickness contributes to rigidity, allowing steady cuts at optimised feed rates and helping to achieve consistent surface quality with fewer passes.

Practical advantages for workshop efficiency

Being double‑sided and indexed, the insert reduces tooling consumption and cost per edge, while the CVD-coated carbide grade T6215 is tuned for the specific demands of stainless steel machining under stable conditions. The combination of standardised dimensions and a proven coating enables quick inventory rotation and simpler tool management across job shops and production lines. For operations seeking dependable series results, this solution supports higher uptime and predictable throughput.
