SNMG 120404 AH6225 — SNMG120404 Turning Insert (PVD-coated), Tungaloy

SNMG120404 AH6225 is an ISO‑standard indexable turning insert designed for external and internal turning of rostfreier Stahl in medium cutting conditions.

• SNMG120404 geometry for ISO toolholders
• PVD-coated carbide grade AH6225
• 0.4 mm corner radius for precise profiling
• Double-sided insert with cylindrical hole

Consistent cutting performance for rostfreier Stahl

The SNMG120404 series offers a PVD-coated carbide body engineered as a universal grade for rostfreier Stahl, balancing a sharp cutting geometry with a robust edge for changing conditions. The combination of the AH6225 grade and the coating produces a controlled wear pattern that supports reliable surface quality and repeatable dimensions during medium turning operations. This focus on consistency reduces unplanned tool changes and supports predictable cycle times on batch or mixed-production runs.

Fast integration into ISO tool systems

As an ISO‑normed plate, the insert fits standard indexable holders when matching form, clearance angle, tolerance class, fastening and thickness. The square plate (inscribed circle 12 mm) with a cylindrical hole and a nominal thickness of 4.76 mm allows straightforward clamping in common external holders and boring bars. The double-sided design doubles the usable edges per index and the 0° relief and 90° included angle provide familiar seating and cutting orientation, easing toolset standardisation and speeding changeovers.

Coating and grade for stable chip formation

The PVD layer on this carbide substrate enhances surface hardness and heat resistance while preserving a sharp initial edge; this enables good chip control with the specified doppelseitig chipbreaker layout. The grade is targeted at medium machining where intermittent cuts or varying feed rates occur, so the insert maintains performance across a range of cutting speeds. Selecting the appropriate chipbreaker variant in concert with the AH6225 grade ensures effective chip evacuation and reduced risk of built-up edge on rostfreier Stahl.

Production benefits and recommended use

Designed for both external and internal turning, the insert supports process stability and cost-efficient use thanks to indexability and a reliable cutting edge. The 0.4 mm corner radius is suitable for precise profiling and limited radii transitions, while the square form provides orientation flexibility. For best results, pair the plate with a holder matched to the ISO geometry and use cutting parameters optimised for medium removal rates; this approach yields a balance between productivity and surface finish without compromising tool life.

FAQ

What materials is this insert best suited to machine?
The SNMG120404 AH6225 Tungaloy insert is formulated primarily for rostfreier Stahl; the PVD-coated carbide substrate and chipbreaker geometry provide stable performance when turning stainless grades.

Is the insert compatible with standard ISO holders?
Yes. The SNMG120404 geometry conforms to ISO standards and is compatible with holders that match the plate form, relief angle, tolerance and thickness.

How many usable edges does the insert offer?
The insert is double-sided, providing multiple indexable cutting edges before replacement is needed, improving cost efficiency per edge.

What corner radius and plate thickness are specified?
The plate features a 0.4 mm corner radius and a thickness of 4.76 mm, suitable for precise profiling and medium cutting conditions.

Does the AH6225 grade include a coating and what is its benefit?
AH6225 is a PVD-coated carbide grade; the coating increases heat and wear resistance while maintaining a sharp cutting edge, which helps with surface finish and consistent tool life on rostfreier Stahl.
