SNMG 120408 AH6225 ISO indexable turning insert — PVD-coated carbide, 0.8 mm radius (Tungaloy)

The SNMG120408 AH6225 is an ISO-format square indexable insert for external and internal turning, optimised for machining rostfreier Stahl and medium-duty operations.

• PVD-coated carbide grade AH6225
• Optimised for rostfreier Stahl machining
• Square ISO insert, 12 mm size, 90° angle
• Double-sided chipbreaker, 0.8 mm corner radius

Reliable cutting performance for rostfreier Stahl

The PVD-coated AH6225 grade provides a balance between a sharp cutting edge and edge stability, making it suitable for variable conditions encountered when machining rostfreier Stahl. The PVD layer improves wear resistance and reduces adhesion, which in turn helps maintain dimensional accuracy over a longer tool life. As an ISO-formatted insert, it supports predictable repeatability in serial production; the combination of carbide substrate and surface coating is designed to reduce flank wear during medium turning, helping to sustain cycle times and part quality.

Consistent chip control and edge life for medium turning

Equipped with a double-sided chipbreaker, this insert promotes controlled chip formation and evacuation during both external and internal turning. The geometry supports stable cutting at moderate feeds and depths of cut, while the 0.8 mm corner radius gives a compromise between edge strength and surface finish. A double-sided design effectively doubles the usable cutting edges per index, reducing downtime for regrinding or replacement and improving overall process economy by increasing usable edge count.

ISO compatibility and straightforward tool integration

The insert is manufactured to ISO dimensions, so compatibility with holders depends on the matching of form, relief (0°) and tolerance class, clamping system, size and thickness. With a 12 mm size, 4.76 mm thickness and a square plate form, it fits standard square-holding systems that accept a cylindrical-hole clamping arrangement. Describing these parameters clearly facilitates correct holder selection and avoids assembly errors; the standardised format supports rapid replacement and predictable set-up in existing tool systems without complex adaptations.

FAQ

What materials is this insert best suited for?
The SNMG120408 AH6225 insert is optimised for machining rostfreier Stahl and offers reliable performance across a range of stainless grades thanks to the PVD-coated carbide grade.

How does the double-sided chipbreaker influence productivity?
The double-sided chipbreaker on this Tungaloy indexable turning insert provides controlled chip formation and doubles the available edges per index, reducing changeover frequency and improving overall process economy.

Which holder characteristics must be checked for compatibility?
Compatibility depends on holder form, relief angle, tolerance class, clamping method, insert size and thickness; the ISO-format SNMG120408 requires a matching square holder with a cylindrical-hole clamping system.

Is the AH6225 grade suitable for variable cutting conditions?
Yes. The AH6225 PVD-coated grade is engineered to balance a sharp cutting edge with stability under changing conditions typical in medium turning operations.

Can this insert be used for internal turning as well as external turning?
Yes. The insert’s geometry and chipbreaking design make it suitable for both external and internal turning, provided the correct holder and clearance are used.
