FNMG 110412 AH6225 Tungaloy turning insert — PVD-coated carbide, 50° cutting angle

A FNMG110412 AH6225 Tungaloy insert for ISO‑standard turning, optimised for stainless steels and neutral to medium cutting conditions.

• PVD-coated carbide grade AH6225
• Designed for stainless steel machining
• Rhombic FNMG geometry with 50° cutting angle
• Double-sided chipbreaker, cylindrical hole for clamping

Optimised cutting performance for stainless steels

The FNMG geometry combined with the AH6225 PVD‑coated carbide provides a balance between edge sharpness and wear resistance, which is particularly beneficial when machining stainless steels. The grade is tuned for variable conditions and intermittent cuts, so the insert sustains a sharp cutting edge while reducing the risk of built‑up edge. The PVD coating improves thermal resistance and lowers friction at the tool–workpiece interface; this translates into more consistent surface finish and extended edge life under medium cutting parameters. For shops seeking reliable outcomes in turning operations, the combination of substrate and coating reduces downtime and supports predictable cycle times.

Precise geometry to simplify set‑up and increase stability

The rhombic plate form and the specified 50° main cutting angle deliver good accessibility for external and internal turning; combined with a corner radius of 1.2 mm, the insert produces robust profiles and improved tool life in interrupted cuts. The zero relief angle (0°) and a plate thickness of 4.76 mm contribute to mechanical stability under radial loads, while the cylindrical hole enables secure clamping in standard ISO holders. Because compatibility depends on form, free angle, tolerance class, clamping and size, the ISO designation helps to match the insert to suitable holders and adaptors quickly, shortening set‑up time and reducing trial adjustments.

Chip control and operational reliability for production environments

This indexable plate is equipped with a double‑sided chipbreaker, which aids controlled chip formation across a range of feeds and depths of cut. The feature improves swarf evacuation and reduces rework risk on longer parts. The plate’s universal focus on stainless steel turning makes it a practical choice where material grades and component geometries vary: a single insert grade can often cover multiple jobs, improving inventory turnover. The ISO conformity and clearly defined dimensions support predictable exchangeability between machines and tool columns, fostering reproducible results and smoother process planning.

FAQ

How is compatibility with toolholders ensured?
Compatibility is determined by form, free angle, tolerance class, clamping method, size and thickness; the ISO designation for this FNMG110412 AH6225 Tungaloy insert assists in matching the plate to standard external holders and boring bars.

Which materials is this grade suitable for?
The AH6225 grade is a universal choice for stainless steels, engineered to provide a sharp, stable cutting edge for medium turning conditions.

What does PVD‑coated carbide mean for tool life?
A PVD coating on a carbide substrate increases thermal and abrasive resistance, reducing adhesion and wear at the cutting edge; this leads to more consistent tool life and improved surface quality when using the FNMG110412 insert.

What are the key geometry values to note?
Relevant dimensions include a corner radius of 1.2 mm, a plate thickness of 4.76 mm, a relief angle of 0° and a main cutting angle of 50°, all of which influence stability and profile integrity.

Why is the chipbreaker and hole important?
The double‑sided chipbreaker controls chip formation across varying feeds, while the cylindrical hole ensures secure clamping, contributing to stable machining and reliable repeatability.
