VNMG 120402 AH6225 — ISO turning insert for turning applications by Tungaloy

The VNMG 120402 AH6225 is an ISO rhombic indexable insert for external and internal turning, designed to provide a balanced cutting edge for medium machining of stainless steel.

• ISO rhombic insert geometry
• PVD-coated carbide AH6225 grade
• Optimised for stainless steel turning
• PS chipbreaker for steady chip control

Reliable edge life through balanced PVD coating and grade selection

The insert uses a PVD-coated carbide substrate in the AH6225 grade, selected to combine a sharp cutting edge with the stability required for medium-duty turning. This balance reduces flank wear while maintaining effective shear, which helps to extend tool life across varying cutting conditions. The controlled edge geometry and the moderate cutting-edge robustness support predictable tool changes and reduced downtime, contributing to a steady production flow and improved process economy.

Consistent chip control and surface quality for stainless steel

Equipped with a PS chipbreaker, the insert achieves reliable chip formation when machining stainless steel, reducing stringing and promoting short, manageable chips. The geometry—rhombic form with a 0.2 mm corner radius and 0° clearance angle—helps maintain a stable cutting line and delivers improved surface finish in medium finishing passes. The 4.76 mm plate thickness and the 35° lead angle provide rigidity at the cutting edge, which translates into fewer vibrations and a more consistent workpiece appearance.

System compatibility and practical workshop integration

The ISO‑compliant design ensures straightforward integration into existing holders and tool systems; compatibility depends on form, relief angle, tolerance class, fastening method, size and thickness. The insert features a cylindrical hole for secure clamping and is supplied in the ISO series intended for reliable replacement and predictable set-up. For workshops aiming to optimise cycle times, the insert supports a modular system approach: matching the insert with a suitable external holder or boring bar, correct clamp set and spare screws yields repeatable clamping and simplified logistics.
