VBMT 160402 AH6225 rhombic turning insert, PVD-coated carbide — Tungaloy

VBMT 160402 AH6225 is a rhombic ISO turning insert designed for reliable external and internal turning of stainless steels; the geometry, chipbreaker and coating are optimised for medium machining and variable conditions

• Universal grade for stainless steels
• PVD-coated carbide for enhanced wear resistance
• ISO rhombic insert with 0.2 mm corner radius
• Centre hole with cylindrical bore and countersink

Consistent machining results thanks to grade and coating

The combination of the AH6225 grade and PVD-coated surface delivers a balance between sharpness and edge stability that is particularly valuable when machining stainless steel. The applied coating reduces adhesion and wear under variable feeds and interrupted cuts, which in turn supports longer tool life and fewer indexings. For operations that require repeatable surface quality, the controlled edge preparation and stable cutting geometry reduce burr formation and workpiece rework. The explanation of PVD: a thin, dense layer deposited by physical vapour deposition that improves abrasion resistance and adhesion without substantially dulling the cutting edge.

Designed geometry and chip control for efficient turning

The rhombic form factor with a 0.2 mm corner radius and a 5° clearance angle produces a predictable cutting engagement that suits medium finishing and general-purpose turning. The TM chipbreaker is configured to form short, manageable chips in a range of stainless grades, improving evacuation and reducing load on the toolholder. The centre bore with a cylindrical hole plus a single-sided countersink (40°–60°) ensures secure clamping and repeatable positioning during index changes. ISO standardisation simplifies inventory management and holder compatibility across common toolholder systems.

Practical benefits for production and process security

Using this PVD-coated carbide insert supports higher process reliability: cutting-edge stability under varying cutting conditions reduces scrap rates and increases throughput. The insert thickness of 4.76 mm and nominal size 16 mm provide stiffness in the assembly to withstand moderate depths of cut without compromising accuracy. For planners and operators, the predictable wear pattern of the grade facilitates maintenance intervals and cost calculations, while the universal focus of the grade minimises the need for multiple specialised inserts in mixed-production environments.

FAQ

What materials is this insert intended for?
The VBMT160402-TM AH6225 is formulated primarily for stainless steel machining; its universal AH6225 grade performs well across a broad range of austenitic and other rust-resistant alloys.

How does the TM chipbreaker influence machining?
The TM chipbreaker on this insert promotes short, controllable chips during turning operations, improving evacuation and reducing the risk of chip-related surface damage with the AH6225 grade.

Which toolholders are compatible with this ISO insert?
Compatibility depends on holder form, clearance, tolerance class, clamping and insert size; the ISO specification and the rhombic shape allow use with standard VBMT-compatible turning holders.

What are the key dimensions to check before assembly?
Verify the insert thickness (4.76 mm), insert size (16 mm), corner radius (0.2 mm) and the centre-hole style to ensure correct seating and clamping in the chosen toolholder.
