SNMG120412 AH6225 indexable insert for turning – Tungaloy

A SNMG120412 AH6225 indexable turning insert designed for ISO-compliant external and internal turning, offering a 90° shape and a 1.2 mm corner radius for reliable medium-duty machining.

• SNMG120412 geometry, 90° shape for versatile turning
• PVD-coated AH6225 grade for stainless steels
• 1.2 mm corner radius for controlled chip formation
• Double-sided insert, cylindrical hole, 4.76 mm thick

Productive turning with a stable, sharp cutting edge

The combination of the AH6225 grade and a PVD-coated surface provides a balance between edge sharpness and wear resistance, which is particularly valuable when machining stainless steels under varying conditions. The coating reduces adhesion and helps to limit built-up edge, improving surface finish and extending effective tool life during medium cutting depths. As a result, stable batch processes and mixed-series production runs benefit from fewer index changes and more predictable performance.

Fast setup and ISO compatibility for efficient production

The ISO SNMG format ensures a standardised fit with compatible holders; compatibility is determined by form, clearance angle, tolerance class, fastening and the insert’s size and thickness. The square SNMG shape with a 90° included angle and a cylindrical hole provides secure clamping and simple indexing. With a plate thickness of 4.76 mm and double-sided chipbreaker configuration, the insert supports easy rotation and replacement, reducing machine downtime and simplifying inventory management for production environments.

Controlled chips and broad applicability in turning

A 1.2 mm corner radius combines edge strength with the ability to form manageable chips, especially when paired with the double-sided chipbreaker geometry. This makes the insert suitable for both external and internal turning tasks where consistent chip control and surface quality are required. The substrate material is carbide, optimised for recurring performance, while the universal AH6225 grade is tuned for stainless steels and medium machining conditions. For detailed setup parameters or specific workpiece materials, consult the process tables or contact the supplier for recommended cutting data.

FAQ

Which materials is this insert best suited for?
The SNMG120412 AH6225 insert from Tungaloy is optimised for machining stainless steels; the AH6225 grade and PVD finish balance sharpness and wear resistance for medium turning tasks.

How is the insert secured in the holder and what determines compatibility?
Compatibility follows the ISO SNMG dimensions: the form, clearance angle, tolerance class, fastening method, insert size and thickness determine fit; the cylindrical hole and square shape facilitate secure clamping in compatible external and internal turning holders.

What benefits does the AH6225 grade and PVD coating provide?
The AH6225 grade is formulated for a sharp yet stable cutting edge in varied conditions, while the PVD-coated surface improves wear resistance and reduces adhesion, leading to more consistent surface finishes and longer effective tool life.

Does the insert support good chip control?
Yes; the 1.2 mm corner radius together with the double-sided chipbreaker promotes controlled chip formation, aiding evacuation and helping to maintain surface quality during medium cutting operations.

Is this insert reversible and suitable for reducing inventory costs?
The double-sided chipbreaker and square geometry permit indexing according to the holder and tool system, enabling multiple cutting edges per physical insert and contributing to economical tool management.
