SNMG120404 AH6225 — ISO turning indexable insert for turning, Tungaloy

SNMG120404 AH6225 is an ISO‑standard square, double‑sided indexable insert designed for external and internal turning with a focus on rostfreier Stahl

• ISO‑standard square insert
• PVD‑coated carbide AH6225
• Double‑sided chipbreaker
• Suitable for rostfreier Stahl

Consistent cutting performance with a universal PVD grade

The combination of a PVD‑coated surface and a tough carbide substrate in grade AH6225 provides a balanced cutting edge that performs reliably under varying conditions. This universal grade is optimised for machining rostfreier Stahl, offering a compromise between sharpness for surface quality and edge stability to resist notch wear. The coating improves heat resistance and reduces adhesion, which translates into fewer interruptions for edge dressing and longer productive tool life. The result is improved process stability and more consistent component quality on batch and single‑piece production.

Predictable fit and repeatability through ISO geometry

The ISO designation ensures compatibility with standard external holders when form, clearance angle, tolerance class, fastening and size are matched. The square shape with an inscribed circle of 12 mm and a nominal clearance angle of 0° yields a rigid seating and reproducible clamping behaviour. With a central cylindrical hole for positive locating and secure fastening, the insert integrates seamlessly into common toolholder systems. This standardisation reduces setup time, simplifies inventory and supports stable machining cycles across different machines and applications.

Design features that reduce downtime and optimise costs

A double‑sided chipbreaker provides two indexed cutting edges per side, effectively doubling usable edges and lowering tool‑consumption costs. The corner radius 0.4 mm offers a compromise between strength and surface finish, while the 4.76 mm thickness improves insert rigidity under interrupted cuts. The combination of sturdy geometry and a modern chip control design reduces built‑up edge and promotes reliable swarf evacuation, which limits machine stoppages and contributes to shorter non‑productive time in series turning and varied batch sizes.

Application range and recommended uses for workshop efficiency

Intended primarily for turning, the insert suits both external and internal operations with a wide span of process demands, especially where rostfreier Stahl is predominant. Select the chipbreaker and insert grade in line with workpiece material, depth of cut and machine stability to unlock the full potential of the cutting edge. For shops seeking predictable surface quality with robust performance under fluctuating conditions, this solution balances finish quality and tool life, supporting higher throughput with controlled costs.

FAQ

What materials is this insert intended for?
The SNMG120404 AH6225 insert is a universal PVD‑coated carbide grade intended primarily for machining rostfreier Stahl and similar demanding alloys.

Is the insert compatible with standard ISO holders?
Yes, the ISO designation and square form enable compatibility with standard external holders when form, clearance, tolerance class, fastening and size are matched.

How does the chipbreaker affect machining?
The double‑sided chipbreaker improves chip control and evacuation, reducing built‑up edge and enabling more stable cutting conditions with fewer interruptions.

Can this insert be used for both roughing and finishing?
With its 0.4 mm corner radius and AH6225 grade, the insert suits medium finishing and general turning tasks; selection of chipbreaker and cutting parameters will determine optimal performance for roughing or finishing.

How many cutting edges are available per insert?
The double‑sided, square geometry provides multiple indexed edges per insert, effectively extending service life before replacement is required.
