VNMG160402-PS AH6225 — VNMG 160402 AH6225 indexable turning insert for turning, PVD-coated carbide, 0.2 mm radius (Tungaloy)

The VNMG160402-PS AH6225 is an ISO-standard rhombic indexable insert designed for external and internal turning; its PVD-coated carbide grade is optimised for sharp, stable cutting edges in varying stainless-steel operations.

• ISO rhombic insert, VNMG form
• PVD-coated carbide grade AH6225
• 0.2 mm corner radius for fine finish
• PS chipbreaker for reliable chip control

Stable cutting under variable stainless-steel conditions

The combination of a PVD-coated surface and the AH6225 carbide grade delivers consistent performance when machining stainless steels under fluctuating cutting conditions. The coating reduces build-up on the cutting edge and supports a sharper geometry, while the substrate provides the necessary toughness for repeated interrupted cuts. This results in improved tool life and fewer process interruptions, supporting a measurable increase in productivity for medium- to general-purpose turning tasks.

Geometry designed for precision and surface quality

The rhombic VNMG form with a 0.2 mm corner radius and a 35° cutting angle yields a balance between edge strength and surface finish. The small corner radius assists in producing finer surface quality and helps to avoid excessive cutting forces in finishing passes. The insert’s 0° relief angle and the available cylindrical central hole ensure secure clamping in standard ISO holders, enabling repeatable positioning and a predictable contact geometry that is easy to integrate into existing tool setups.

Simple integration, low-maintenance operation

Being ISO-standardised, the insert fits a wide range of external holders and boring bars when the holder’s form, clearance, tolerance class, fastening method, size and thickness match. The PS chipbreaker supports manageable chips for both external and internal turning, reducing the need for frequent manual intervention. Combined with the universal character of the grade, this insert offers an economical route to stable machining: fewer tool changes, consistent surface quality and straightforward stock management when paired with compatible toolholders.

FAQ

Which materials is this insert best suited for?
The VNMG160402-PS AH6225 is formulated as a universal grade for stainless steels, offering a balanced edge for mid-range machining and varying conditions.

What does the PS chipbreaker provide?
The PS chipbreaker on the VNMG160402-PS optimises chip formation for turning operations, promoting controllable chips and reducing the likelihood of tangling during external and internal turning.

How does the insert integrate with existing holders?
Compatibility is determined by insert form, relief angle, tolerance class, fastening method, size and thickness; the ISO-standard VNMG form fits standard VNMG holders when those parameters match.

What are the measurable geometry values to consider?
Key dimensions are a 0.2 mm corner radius, 16 mm insert size and 4.76 mm thickness; note the 35° cutting angle and the cylindrical central hole for secure clamping.

What is the manufacturer article number and SKU?
