VNMG 160408 AH6225 turning insert — PVD-coated carbide for turning, Tungaloy

The VNMG160408 AH6225 is a rhombic, ISO-design turning insert engineered for external and internal turning with a double-sided chipbreaker and cylindrical hole for secure clamping.

PVD-coated carbide universal grade AH6225 Rhombic 35° geometry for versatile turning 0° clearance angle for predictable cutting behaviour Corner radius 0.8 mm for improved edge stability

Consistent cutting performance for stainless steels

The insert’s PVD-coated carbide substrate and the AH6225 universal grade are optimised for machining stainless steels under varying conditions. The coating increases resistance to built-up edge while the substrate maintains cutting-edge stability, so mid-range feeds and interrupted cuts remain predictable. This combination reduces unplanned rework and supports higher first-pass yields, making the component suitable for batch production and mixed-series manufacturing environments where process repeatability is essential.

Compatibility and mechanical design that simplify integration

Designed to ISO standards, the 35° rhombic shape and the cylindrical hole ensure compatibility with a wide range of ISO external holders and boring bars; the 4.76 mm thickness and 16 mm size align with standard clamping systems. The double-sided chipbreaker provides two available cutting edges per insert, improving economy per cutting edge. Where holder fit and tolerance class determine assembly, the geometry and hole style support secure fixation and consistent seating, thereby reducing vibration and aiding surface quality.

Practical benefits for machining operations and tool selection

Choosing this insert supports efficient tool life management: the corner radius 0.8 mm balances edge strength and surface finish, while the 0° clearance angle creates a predictable shear condition that complements medium-depth turning strategies. For shops moving between alloyed and non-alloyed stainless grades, the insert’s balance of sharpness and edge robustness simplifies grade selection and reduces the need for frequent inserts changes. Maintenance is straightforward: replacing a worn edge restores cutting parameters without altering holder set-up or process windows.

FAQ

What materials is this insert intended for?
The VNMG160408 AH6225 insert is a PVD-coated carbide grade tailored as a universal solution for machining stainless steels and related alloys.

How does the 0° clearance angle affect cutting?
A 0° clearance angle promotes a consistent cutting geometry and stable edge contact; this benefits medium cutting depths where predictable chip formation and surface finish are priorities.

Is the insert compatible with standard ISO holders?
Yes — the insert follows ISO turning insert dimensions and the rhombic shape with cylindrical hole is compatible with matching ISO external holders and boring bars.

How many cutting edges are available per insert?
The double-sided chipbreaker provides two usable cutting edges per insert, improving cost-effectiveness and reducing tool-change frequency.

What distinguishes the AH6225 grade from other grades?
AH6225 is a PVD-coated universal grade developed for a balance of sharpness and edge stability, offering good performance across varied stainless-steel machining tasks.
