SNMG 120404 AH6225 Tungaloy indexable insert – for turning

The SNMG120404 AH6225 Tungaloy indexable insert is an ISO‑standard, square insert engineered for versatile external and internal turning of stainless steels, combining a sharp yet robust cutting edge with a double‑sided chipbreaker.

• PVD-coated carbide grade AH6225
• Optimised for stainless steel turning
• 0.4 mm corner radius for finishing
• Cylindrical hole, double-sided chipbreaker

High cutting performance and material suitability

The combination of AH6225 and a PVD‑coating provides a balanced blend of wear resistance and toughness, which is particularly beneficial when machining stainless steels under varying conditions. The coated carbide substrate reduces built‑up edge formation and improves surface finish at medium cutting regimes. For production environments where process stability matters, this geometry supports consistent results by offering a sharp, stable cutting edge that resists edge chipping while maintaining acceptable tool life. Technical terms: PVD stands for physical vapour deposition, a thin hard coating that increases abrasion resistance without significantly reducing toughness.

Easy integration into ISO tooling systems

The SNMG form (ISO designation 120404) is a square, 90° insert designed for straightforward mounting in compatible external holders or boring bars. Compatibility is determined by form, free angle, tolerance class, fastening, size and thickness, so a correct holder selection ensures secure clamping and predictable performance. This insert features a cylindrical hole and accepts the common fastening systems used in ISO tooling, while the 0° relief angle and a 4.76 mm plate thickness provide a stable platform for moderate to heavy interrupted cuts. The double‑sided configuration permits indexation, effectively doubling the number of usable edges and lowering per‑edge cost in high‑volume applications.

Practical selection and process recommendations

Choose the chipbreaker and grade to match the specific workpiece and machining strategy: the supplied double‑sided chipbreaker is suitable for a broad range of turning tasks, while the AH6225 grade is optimised for mid‑range stainless steel applications where a balance of edge sharpness and stability is required. For best results, use a rigid tool setup, moderate feed to exploit the 0.4 mm corner radius for improved surface finish, and appropriate cutting fluid to manage heat and adhesion on sticky alloys. Optimising these parameters improves cycle time, reduces scrap and enhances overall process economy.

FAQ

What materials is this insert suitable for?
The SNMG120404 AH6225 insert is formulated for stainless steels and performs well in mid‑range turning tasks where a stable, sharp edge is required.

How many cutting edges are available per insert?
Thanks to the double‑sided chipbreaker and the square geometry, the insert provides multiple indexable edges, effectively reducing tooling costs per edge.

Is the insert compatible with standard SNMG holders?
Yes, the SNMG120404 geometry follows ISO standards; compatibility is defined by holder form, free angle, tolerance class, fastening, size and thickness—select a matching SNMG holder for secure mounting.

What are the benefits of the AH6225 grade and the PVD coating?
The AH6225 grade offers a balance of sharpness and edge stability, while the PVD coating improves abrasion resistance and helps prevent built‑up edge when machining stainless steels.
