SNMG 120402 AH6225 indexable turning insert for turning, Tungaloy

SNMG120402 AH6225 Tungaloy indexable insert designed for ISO-standard turning operations, offering a sharp yet stable cutting edge for medium machining of stainless steels in external and internal turning.

• Universal grade for stainless steels
• PVD-coated carbide for wear resistance
• Double-sided chipbreaker for versatility
• Square geometry with 90° approach angle

Reliable performance from a universal PVD-coated grade

The combination of the AH6225 grade and PVD-coated carbide provides a balance between edge sharpness and wear resistance, resulting in consistent cutting performance under variable conditions. The coating reduces adhesive wear and improves thermal stability, which helps to maintain a stable cutting edge during medium turning operations. As a result, machining cycles show improved repeatability and a more consistent surface finish, especially when processing work-hardening materials such as stainless steels.

Straightforward integration into ISO tooling systems

Designed to ISO dimensions, the insert fits standard holders when form, relief angle and tolerance class match; compatibility depends on insert shape, relief (0°), fastening and thickness. The square insert geometry and the presence of a cylindrical hole simplify clamping and orientation, reducing changeover time. This standardisation enables straightforward replacement in existing tool assemblies and supports predictable toolset-up, which contributes to shorter downtimes and a smoother production flow.

Effective chip control for stainless steel turning

The double-sided chipbreaker is optimised for chip control in medium turning of stainless materials, helping to avoid long, stringy chips and reducing the risk of re-cutting. Good chip control supports higher process security and a safer machining environment, while also protecting the machined surface. The breaker geometry, paired with the AH6225 grade, is particularly suitable where alternating cutting conditions occur and where balanced performance between finish and tool life is required.

Robust geometry for dimensional accuracy and edge strength

A 0.2 mm corner radius together with a plate thickness of 4.76 mm ensures a stable cutting edge that withstands interrupted cuts and light finishing passes. The 90° approach angle and the square form allow precise shoulder and contour turning with predictable tool deflection characteristics. These geometric attributes contribute to accurate component dimensions and repeatable machining results in demanding production settings.

FAQ

Which materials is this insert suitable for?
The SNMG120402 AH6225 insert is optimised for stainless steels, offering a universal compromise between edge sharpness and robustness for medium turning tasks.

How is the insert secured in the holder?
Compatibility depends on form, relief angle and tolerance class; the SNMG120402 uses a cylindrical hole and standard ISO clamping interfaces typical of square indexable inserts.

What advantage does the AH6225 grade deliver?
The AH6225 PVD-coated carbide provides improved wear resistance and thermal stability, extending effective cutting life while maintaining a sharp cutting edge under varying conditions.

Is the insert single- or double-sided?
This Tungaloy insert is double-sided with a chipbreaker on both faces, allowing cost-effective indexation and extended usage before disposal.

What is the corner radius and why does it matter?
The corner radius is 0.2 mm, offering a balance between edge strength and the ability to achieve fine surface finishes; it is suitable for precise shoulder and contour turning.
