SNMG 120404 AH6225 ISO indexable turning insert — PVD-coated carbide, 0.4 mm radius | Tungaloy

SNMG 120404 AH6225 is an ISO-standard indexable turning insert engineered for external and internal turning operations, optimised for stainless steels and medium machining conditions.

• PVD-coated carbide grade AH6225
• Optimised for stainless steel machining
• Double-sided chipbreaker for reliable chips
• ISO SNMG120404 square insert, 0.4 mm radius

Stable, sharp cutting for consistent material removal

The SNMG 120404 AH6225 is built on a PVD-coated carbide substrate that combines a sharp cutting edge with edge-line stability for medium cutting tasks. The AH6225 grade is specified as a universal option for stainless steels, delivering a balance between wear resistance and edge toughness across varying conditions. The insert’s double-sided chipbreaker promotes predictable chip formation, reducing the risk of built-up edge and minimising interruptions in production. For non-specialists: the PVD layer increases hardness at the surface and improves heat resistance, so the insert holds its geometry longer under elevated cutting temperatures.

Improved surface finish and productive cycle times

A 0.4 mm radius at the corner and a 90° included angle create a robust edge geometry that supports consistent contact with the workpiece and reduces deflection in typical lathe setups. This geometry helps to achieve a better surface finish while maintaining process stability, which in turn can lower cycle times by reducing secondary operations and rework. The nominal 4.76 mm thickness contributes to rigidity when clamped in compatible holders, meaning fewer tool changes and improved overall machining economy. In practice, the combination of grade, coating and geometry supports repeatable results and predictable tool life in series production.

Simple integration into existing turning systems

Produced to ISO norms, this indexable insert integrates into standard external holders and boring bars when matched by shape, relief angle, tolerance class, clamping method, size and thickness. The typical system comprises the ISO insert, a suitable external holder or boring bar, a clamp set and replacement screws, allowing straightforward replacement and re-indexing. The square, double-sided design extends usable edges and reduces inventory complexity. For workshops seeking process stability, this insert offers a pragmatic route to consistent turning performance with familiar clamping arrangements.
