SNMG120416 AH6225 Tungaloy indexable insert for turning

SNMG120416 AH6225 is an ISO‑standard indexable insert for external and internal turning, designed for medium machining of rostfreier Stahl.

• PVD-coated carbide grade AH6225
• Optimised for rostfreier Stahl machining
• Square insert with 90° cutting angle
• Double-sided chipbreaker, cylindrical hole

Consistent performance with a universal cutting grade

The SNMG120416 AH6225 insert combines a PVD coating with a carbide substrate to balance edge sharpness and wear resistance for medium‑duty turning of rostfreier Stahl. The coating lowers adhesion and improves heat resistance, which translates into steadier cutting forces and more consistent surface finishes under varying cutting conditions. For production environments where material batches and machine stability can fluctuate, this insert offers predictable tool behaviour and simpler process windows, reducing the need for continuous parameter fine‑tuning.

System compatibility that simplifies tool planning

As an ISO series indexable insert, the plate’s compatibility with toolholders depends on shape, relief angle, tolerance class, attachment style, size and thickness. The squared form with a 90° included angle and a cylindrical hole makes mechanical clamping straightforward on standard external holders and boring bars, while the 4.76 mm plate thickness contributes to bending stiffness. Specifying the correct holder, shim and clamping set ensures repeatable clamping accuracy and minimises vibration, which in turn protects the cutting edge and extends usable life per edge.

Improved chip control for steady productivity

The double‑sided chipbreaker design provides reliable chip segmentation during both external and internal turning, helping to avoid long, entangling swarf and reducing cycle interruptions. The 1.6 mm corner radius increases edge robustness for interrupted cuts and moderate depth of cut, offering a compromise between edge strength and dimensional control. In practical terms, workshops achieve fewer tool changes and more uninterrupted spindle time, which contributes to higher throughput and lower unit production cost.

Practical benefits for workshop workflows

Using a universal, PVD‑coated carbide grade streamlines inventory: one grade covers a wide range of rostfreier Stahl applications, lowering the number of tool types stocked. The ISO format facilitates quick index changes; a double‑sided insert delivers two cutting edges per index, improving cost efficiency. Clear identification of form, size and tolerance reduces setup times and helps maintain machining quality across shifts and operators, supporting predictable delivery performance for batch and single‑piece manufacturing.

FAQ

What materials is this insert suited for?
The SNMG120416 AH6225 insert is optimised for machining rostfreier Stahl and performs well in medium turning operations where a balance of edge sharpness and stability is required.

Is the insert reversible or single‑use per face?
This is a double‑sided indexable insert; each indexing provides a fresh cutting edge, improving cost efficiency and reducing tool change frequency.

How does the PVD coating benefit machining?
The PVD coating on the carbide substrate reduces adhesion from rostfreier Stahl, raises thermal resistance and helps maintain edge integrity under variable cutting conditions, resulting in steadier cut quality.

Which holders are compatible with this insert?
Compatibility depends on holder form, relief angle, tolerance class, attachment and size. The ISO designation and cylindrical hole allow use with standard external holders and appropriate boring bars when matched to the insert dimensions.

What cutting scenarios suit the 1.6 mm corner radius?
A 1.6 mm corner radius provides enhanced edge strength for interrupted cuts and moderate depths of cut while still allowing acceptable dimensional accuracy; it is a pragmatic choice for general‑purpose rostfreier Stahl turning.
