VNMG 120404 AH6225 Wendeplatten - Tungaloy

Benefit from a combination of a sharp, stable cutting edge provided by the PVD‑coated AH6225 grade and the ZF chipbreaker engineered for stainless steels to secure consistent surface finish and process reliability in medium‑duty turning. The rhombic VNMG form with a 0.4 mm corner radius and 35° cutting angle offers predictable chip control and repeatable seating in ISO holders; order the insert directly via Metav Werkzeuge or ask their consultants for matching holder specifications.

VNMG120404 AH6225 — ISO turning insert, PVD-coated carbide, ZF chipbreaker by Tungaloy

A VNMG120404E‑ZF AH6225 ISO turning insert for external and internal turning, designed for medium‑duty machining of stainless steels with a balance of sharpness and edge stability.

• PVD‑coated carbide grade AH6225
• ZF chipbreaker for stainless steels
• Rhombic VNMG 12, 35° cutting angle
• 0.4 mm corner radius, 4.76 mm thickness

Consistent cutting edge for repeatable production results

The insert uses a PVD‑coated carbide substrate in the AH6225 grade that combines wear resistance with a finely honed edge geometry. This composition supports sustained cutting performance during interrupted cuts and changing conditions, reducing the need for frequent index changes. The ZF chipbreaker is tailored for stainless steels, improving chip evacuation and lowering the risk of built‑up edge formation; this leads to fewer surface defects and a steadier cycle time in serial turning operations.

ISO compatibility and secure clamping for automated setups

Designed as an ISO‑standard indexable plate, the rhombic VNMG form and the central cylindrical hole ensure compatibility with common external holders and boring bars. The 35° cutting angle and the defined 0° relief angle promote a stable engagement and minimise vibration in less rigid setups. As the insert is specified to fit by form, size, thickness and fastening, integration into an existing tool system is straightforward when matching the holder’s tolerance class and screw type.

Optimised for stainless steel turning with reliable chip control

For turning of stainless steels, the combination of a sharp edge and the ZF chipbreaker supports short, manageable chips and lowers thermal loads at the cutting edge. Medium feed and speed ranges benefit from the insert’s balance between edge toughness and sharpness: the tool resists edge chipping while still providing clean shearing, resulting in improved surface finish and dimensional stability on both external and internal contours.

Practical handling, inspection and economical use

The insert’s rhombic geometry and 0.4 mm corner radius make it suitable for both finishing and light medium machining where a controlled corner is required. Its 4.76 mm thickness affords adequate rigidity for repetitive cycles, while the PVD layer adds protection against adhesion and abrasive wear. For workshop logistics, the ISO designation simplifies stock management and reordering; pairing the insert with the correct holder and clamp set reduces downtime and supports predictable tool‑life planning.

FAQ

What materials is this insert designed for?
The Tungaloy VNMG120404E‑ZF AH6225 insert is formulated primarily for stainless steels and performs well in medium‑duty turning operations.

How does the ZF chipbreaker affect machining performance?
The ZF chipbreaker on the VNMG insert promotes short, controllable chips and improved chip flow, which helps maintain surface quality and reduces tool‑related interruptions.

Which holder features must be checked for compatibility?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; ensure the holder matches the ISO plate dimensions and central hole style for secure seating of the VNMG insert.

Is the AH6225 grade suitable for interrupted cuts?
The PVD‑coated AH6225 carbide grade combines a sharp cutting edge with sufficient toughness for interrupted and variable‑condition turning, offering stable performance in many stainless‑steel applications.
