SNMG 120404 AH6225 turning insert by Tungaloy – PVD-coated carbide, 0.4 mm radius

SNMG120404 AH6225 Tungaloy turning insert for ISO-standard turning applications, designed for reliable performance on stainless steels and adaptable to a wide range of holders

• PVD-coated carbide for stainless steels
• ISO SNMG120404 geometry for compatibility
• Double-sided chipbreaker for versatile use
• 0.4 mm nose radius for stable cutting

Consistent performance for stainless-steel turning

The SNMG120404 AH6225 indexable insert is specified as a PVD-coated carbide grade engineered for turning of stainless steels. The grade delivers a sharp yet stable cutting edge, which is beneficial in mid-range machining and in changing workpiece or cutting conditions. This results in improved process reliability and more predictable tool life, helping to reduce downtime and maintain surface quality. The coating aids wear resistance while preserving edge integrity during intermittent or continuous cuts.

Geometry and measures that enable secure mounting

The insert follows the standard SNMG geometry with ISO code 120404, providing a recognised fit for compatible external holders and boring bars. Key dimensions include an inscribed size of 12 mm, a plate thickness of 4.76 mm, a nose radius of 0.4 mm and a 90° lead angle; the relief angle is 0°. Correct compatibility depends on the holder’s form, relief, tolerance class, fastening method, size and thickness, so matching these parameters ensures correct seating and stable cutting conditions. The cylindrical hole supports accurate clamping and repeatable positioning in ISO-compatible toolholders.

Workshop advantages: handling, indexing and application scope

The square plate form combined with a double-sided chipbreaker provides practical benefits at the machine: multiple indexing positions allow economical use of each insert and the chipbreaker supports controlled chip formation for improved surface finish. As an ISO-standard indexable plate, it is straightforward to replace and to source as part of a system comprising holder, support shim and clamping set. The universal character of the AH6225 grade makes it suitable as a go-to choice for turning tasks on stainless steels, offering a balance between edge sharpness and robustness for everyday workshop use while simplifying inventory management.

FAQ

What materials is this insert suited for?
The AH6225 grade is a universal PVD-coated carbide developed primarily for stainless steels, providing a balance of edge sharpness and stability for varied turning tasks.

What are the key dimensions to check for holder compatibility?
Check the SNMG geometry (ISO 120404), inscribed size 12 mm, thickness 4.76 mm and nose radius 0.4 mm; the holder must match form, relief angle, tolerance class, fastening and plate thickness.

Is the insert reversible or single-use per edge?
The square plate with a double-sided chipbreaker offers multiple indexing positions, allowing several usable edges before replacement.

How does the PVD coating affect performance?
The PVD coating improves wear resistance while maintaining edge sharpness, supporting stable cutting during mid-range machining and under variable conditions.

Does the insert require a specific clamping screw or shim?
Compatibility is determined by the holder design and clamping system; the plate has a cylindrical hole for secure clamping in ISO-compatible toolholders.

Can this insert be used for both external and internal turning?
Yes; the SNMG form and AH6225 grade are suitable for external and internal turning when the correct holder and cutting parameters are selected.
