SNMG 120412 AH6225 – ISO turning indexable insert by Tungaloy, PVD-coated carbide, 90°

The SNMG120412 AH6225 is an ISO-format indexable turning insert designed for external and internal turning applications, offering a sharp yet stable cutting edge for machining a range of stainless steels under varying conditions.

• PVD-coated carbide grade AH6225
• Optimised for stainless-steel turning
• 1.2 mm corner radius for robust cutting

High-performance grade for consistent stainless-steel machining

The insert’s PVD-coated carbide composition is tailored to deliver a balance of edge sharpness and wear resistance that suits medium-duty operations. The AH6225 grade has been formulated for a broad range of stainless steels, providing predictable tool life where cutting conditions may vary. This results in fewer interruptions for insert changes and a more consistent surface finish, which supports stable process planning and improved throughput on turning operations.

ISO format and geometric clarity speed up integration

Supplied in the standard ISO designation, the insert is straightforward to match with compatible external holders or boring bars: compatibility is determined by form, clearance angle, tolerance class, fixing method, size and thickness. The square shape with a 90° included angle plus a cylindrical hole ensures secure clamping and repeatable positioning in common clamping systems. Clear geometric data simplifies tooling selection and reduces setup time in production environments.

Reliable chip control and edge security for productive turning

A double-sided chipbreaker provides consistent chip formation and evacuates swarf efficiently during both external and internal turning. The 1.2 mm corner radius increases edge robustness for interrupted cuts and variable feeds, reducing the risk of premature edge chipping. Together with the PVD finish, these features extend usable edge life and help maintain dimensional accuracy over longer tool cycles, lowering total tooling cost per component.

Workshop-friendly system concept and practical use

The system approach comprises the ISO insert combined with a matching holder, underlay or clamp set, and replacement screws; this modularity allows for rapid insert replacement and minimal machine downtime. For workshops processing stainless steels in mixed batches, the combination of a universal grade and an ISO-format insert supports flexible production planning. If further machining data are required, the technical advisers at Metav Werkzeuge can provide cutting parameters and holder recommendations for specific workpiece alloys and machine conditions.
