VNMG 120404 AH6225 ISO turning insert – PVD-coated carbide, 0° relief | Tungaloy

The VNMG120404E-TM AH6225 is an ISO turning insert designed for external and internal turning, offering a balance of sharpness and edge stability for machining stainless steels.

• PVD-coated cemented carbide AH6225
• Universal grade optimised for stainless steels
• Rhombic VNMG form with 0.4 mm corner radius

Consistent cutting performance for stainless steels

The AH6225 grade combines a PVD-coated surface with a cemented carbide substrate to deliver consistent wear resistance and reduced adhesion when machining stainless steels. This composition supports a sharp, stable cutting edge that maintains dimension and surface quality under fluctuating conditions. The coating reduces built-up edge and increases thermal stability, which helps to extend tool life during medium-duty turning operations.

Geometry engineered for process stability

The VNMG rhombic format, with a 0.4 mm corner radius and a plate thickness of 4.76 mm, provides a robust seat in the toolholder and improved vibration damping. The insert’s 0° relief angle ensures predictable contact and is suitable for matched holders designed for ISO inserts; the presence of a cylindrical hole assists secure clamping. These geometric choices contribute to reproducible part tolerances and reduced tool-change downtime in serial production.

Reliable chip control and flexible application

Equipped with the TM chipbreaker, the insert is aimed at medium machining where chip control and consistent evacuation are essential. The chipformer and the universal grade allow use across a broad range of stainless grades and varying cutting conditions. Compatibility with the machining set-up is defined by insert form, relief angle, tolerance class, fastening method, size and thickness, so the insert integrates into standard ISO tool systems for turning and boring.

Practical system integration and process benefits

As an ISO-standard indexable insert, the VNMG120404E-TM AH6225 fits into established systems comprising an appropriate external holder or boring bar, a support shim or clamping kit, and standard replacement screws. The combination of a universal carbide grade, precise plate geometry and a factory-specified chipbreaker supports efficient cycle times, consistent surface finish and reliable repeatability in component production. The SKU and manufacturer references facilitate reordering and process documentation.

FAQ

Which materials is this insert best suited for?
The VNMG120404E-TM AH6225 is optimised for machining stainless steels, with the AH6225 grade providing a balance of edge sharpness and wear resistance suited to medium turning operations.

What benefits does the PVD coating bring?
The PVD layer on the cemented carbide improves thermal resistance and reduces adhesion, helping to avoid built-up edge and extending effective tool life during varied cutting conditions with the VNMG geometry.

How does the TM chipbreaker influence machining?
The TM chipbreaker promotes controlled chip formation and evacuation in medium machining, improving process reliability and surface finish while reducing the risk of entanglement.

How can compatibility with holders be ensured?
Compatibility is determined by the insert form, relief angle, tolerance class, fastening method, plate size and thickness; match the VNMG120404E-TM dimensions and clamping style to a suitable ISO holder.
