SNMG 120402 AH6225 Wendeplatten - Tungaloy

Take advantage of the combination of a PVD-coated carbide grade (AH6225) and a 90° square geometry to achieve consistent, stable cuts in stainless steel; the 0.2 mm corner radius supports fine finishing while the double-sided chipbreaker extends service intervals. Order the insert directly via Metav Werkzeuge or consult the technical team for mounting compatibility and cutting-parameter advice.

SNMG120402 AH6225 SNMG turning insert by Tungaloy — PVD-coated carbide, 90° square

The SNMG120402 AH6225 is an ISO-standard turning insert designed for external and internal turning; its square form and cylindrical hole ensure reliable clamping and repeatable positioning.

• PVD-coated carbide AH6225
• Optimised for stainless steel machining
• Double-sided chipbreaker for flexible cutting
• 90° square form for stable cutting

Stable performance on stainless steel at variable conditions

The combination of the AH6225 PVD coating and a carbide substrate delivers a cutting edge that balances sharpness and robustness for medium machining. The coating reduces built-up edge formation when machining stainless steel, which in turn keeps surface finish consistent and diminishes rework. For production environments where material batches and cutting conditions vary, this composition helps maintain feed and speed settings longer before adjustment is required, supporting predictable cycle times and fewer tool changes.

ISO form and geometry that simplify holder selection and setup

Built to ISO dimensions, the square 90° geometry and cylindrical hole make the insert compatible with a wide range of ISO external holders and boring bars; compatibility is determined by form, clearance angle, tolerance class, fixing method, size and thickness. The 0.2 mm corner radius provides a compromise between strength and edge acuity: small radii improve finish on light cuts, while the square form gives rigid support for heavier cross-sections. Clear labelling and standardised sizing reduce setup time and lower the risk of incorrect clamping.

Productivity gains through stable chip control and economical indexing

The double-sided chipbreaker affords two cutting edges per side, enabling efficient chip control across common turning tasks and extending the usable life of each insert through simple indexing. This reduces tool-change downtime and raises process throughput. Selecting the correct chipbreaker style and pairing it with the AH6225 grade supports consistent cutting forces and helps protect the cutting edge during interrupted cuts, which in turn contributes to lower overall machining costs and improved plant efficiency.

FAQ

What materials is this insert suitable for?
The SNMG120402 AH6225 Tungaloy insert is designed as a universal grade for stainless steel and performs well across a range of stainless and alloyed materials when cutting parameters are matched.

How does the AH6225 coating affect tool life?
The PVD-coated AH6225 grade improves edge stability and reduces adhesion on the cutting edge, which generally extends the interval between indexings and replacements for the insert.

Is the insert reversible or single-use per side?
The insert features a double-sided chipbreaker, allowing multiple indexings; this extends the number of available cutting edges and enhances cost-efficiency per insert.

Which holder types are compatible with this ISO insert?
Compatibility depends on the holder’s form, clearance angle, tolerance class, fixing method, size and thickness; the ISO-standard dimensions of this insert simplify selection of compatible external holders and boring bars.

What cutting applications is the insert intended for?
This insert is recommended for both external and internal turning tasks, offering a balance between finish quality and edge robustness suitable for medium machining and variable operating conditions.
