SNMG120404 T6215 SNMG — ISO turning insert for turning by Tungaloy

A SNMG120404 T6215 ISO turning insert engineered for productive and wear-resistant turning of stainless steels under stable to lightly interrupted conditions.

• CVD-coated wear-resistant grade
• Designed for stainless steel machining
• Double-sided chipbreaker for consistent chips
• ISO SNMG 120404 geometry, 90° square insert

Reliable cutting performance for stainless-steel turning

The CVD-coated T6215 grade combines a robust substrate with a chemical vapour deposition layer to extend tool life in demanding conditions. This formulation is optimised for machining stainless steel, reducing flank wear and improving edge stability under moderate interruption. The combination of coating and carbide base results in a more consistent cutting edge, which translates into fewer tool changes and improved uptime on turning centres. For operations that prioritise predictable tool life, the grade offers a measurable benefit in process stability and component quality.

Precise geometry and ISO compatibility for easy integration

The square 12 mm format, 4.76 mm plate thickness and 90° shape provide a familiar geometry for indexable turning applications, while the 0.4 mm corner radius supports dimensional control on external and internal profiles. The cylindrical hole and standard ISO dimensions ensure compatibility with common SNMG holders and boring bars; compatibility depends on form, relief angle, tolerance class, fastening method, size and thickness. Clear mechanical interfaces and standardised mounting simplify inventory management and minimise set-up time across different machines and fixtures.

Productivity and chip control that support shop-floor goals

A double-sided chipbreaker design delivers repeatable chip formation and evacuation for many stainless-steel operations, reducing the risk of built-up edge and improving surface finish. By matching the chipbreaker style and grade to material and machining stability, cutting forces can be stabilised and cycle times optimised. The insert’s reversible nature doubles the effective cutting edges per insert, enhancing cost-efficiency and lowering per-part tooling costs. Together, predictable chips and a robust grade contribute directly to a more economical and reliable turning process.

FAQ

What materials is this insert intended for?
The SNMG120404 T6215 insert is specified for machining stainless steel; the CVD coating and grade support wear resistance under stable to lightly interrupted turning.

Is the insert compatible with standard SNMG holders?
Yes, the SNMG120404 geometry follows ISO dimensions and uses a cylindrical-hole mounting; compatibility is determined by holder form, relief angle, tolerance class, fastening type, size and thickness.

How does the double-sided chipbreaker help in production?
The double-sided chipbreaker on this indexable insert provides consistent chip formation and evacuation, improving surface finish and reducing the likelihood of built-up edge during turning of stainless steels.

Can the insert be rotated to use multiple edges?
The SNMG-style square insert is reversible; rotating or flipping the insert allows access to additional cutting edges, effectively extending tool life and lowering tooling cost per component.

What are the key dimensional data to check before ordering?
Verify the designation SNMG120404, 12 mm size, 4.76 mm thickness, 0.4 mm corner radius and the 90° geometry to ensure correct fit with the intended holder.
