SNMG 120404 AH6225 – ISO turning insert for turning, Tungaloy

The SNMG120404 AH6225 Tungaloy insert is an ISO-standard indexable turning insert designed for external and internal turning of stainless steels and similar materials.

• PVD-coated carbide grade AH6225
• Optimised for stainless steels
• Double-sided chipbreaker
• ISO SNMG 120404, 0.4 mm corner radius

Consistent performance for stainless-steel machining

The combination of a PVD-coated carbide substrate and the AH6225 grade delivers a balance between a sharp cutting edge and edge stability for mid-range cutting conditions. This configuration reduces built-up edge risk when machining stainless steels, so operators benefit from improved dimensional consistency and fewer interruptions. The result is a reliable cutting process that supports steady cycle times and predictable tool-change intervals.

Clear chip control and edge security for fewer interruptions

An integrated double-sided chipbreaker and the geometrical design of the insert ensure reliable chip formation and evacuation during both external and internal turning. The 0.4 mm corner radius helps maintain an even wear pattern and supports edge strength where interrupted cuts or variable conditions occur. Good chip control reduces the likelihood of rework and protects the workpiece surface finish, enhancing overall process efficiency.

ISO compatibility that simplifies tooling decisions

Being an ISO SNMG 120404 plate, the insert fits standard SNMG external holders when form, clearance angle, tolerance class, fastening and thickness match the holder specification. The indexable design with a cylindrical hole and square form enables straightforward indexing and replacement, while the specified 4.76 mm thickness ensures mechanical stability in the tool pocket. This compatibility reduces tooling complexity across workshops using standard toolholders.

Practical benefits for everyday production

In practice, the insert supports a broad range of turning tasks thanks to the universal AH6225 grade: it is suitable for varying stainless-steel grades and changing cutting conditions without frequent grade swaps. Reduced tool change frequency and stable edge life contribute to higher productivity and lower lifecycle costs. The insert’s design also allows straightforward integration into a system comprising an external holder, shim or clamp set and replacement screws for fast maintenance.

FAQ

Which materials are recommended for this insert?
The SNMG120404 AH6225 Tungaloy insert is optimised for stainless steels and performs well in mid-range turning operations where a sharp yet stable cutting edge is required.

Will this plate fit standard SNMG holders?
Compatibility with SNMG holders depends on holder form, clearance angle, tolerance class, fastening, size and thickness; the ISO designation SNMG120404 indicates suitability for standard SNMG toolholders that match these dimensions.

What are the advantages of the AH6225 grade?
AH6225 is a PVD-coated carbide grade developed for a balance of sharpness and edge robustness, giving good wear resistance and consistent performance across varying conditions when machining stainless steels.

How does the chipbreaker influence machining?
The double-sided chipbreaker promotes controlled chip formation and evacuation, which improves surface finish and reduces the risk of chip-related interruptions during turning.

Is the insert reversible and easy to index?
Yes, the plate is double-sided and indexable, featuring a cylindrical hole and a square form that allow straightforward indexing and replacement to extend tool life.
