• Rhombic ISO insert with cylindrical hole

Consistent performance for rostfreier Stahl with a universal grade

The PVD-coated carbide grade AH6225 is formulated as a universal choice for machining rostfreier Stahl, offering a balance between a sharp cutting edge and sufficient edge stability for medium machining operations. This composition supports repeatable results when cutting conditions vary, reducing the risk of premature flank wear while maintaining good surface quality. The combination of a sharp geometry and a robust substrate provides a dependable option for shops seeking predictable tool life and process stability.

Reliable edge geometry and effective chip control

A corner radius of 0.4 mm combined with the TM chipbreaker promotes controlled chip formation and evacuation during turning, which directly improves surface finish and reduces the likelihood of built-up edge when machining sticky alloys. The insert's 0° rake angle and rhombic geometry contribute to predictable cutting forces and a favourable contact pattern at the tool edge. These characteristics simplify process parameter selection and help maintain part tolerances across short production runs and finishing passes.

Designed for secure mounting and broad ISO compatibility

The insert follows ISO norms for shape and size, featuring a cylindrical hole and an inscribed circle size of 16 mm with a plate thickness of 4.76 mm, enabling compatibility with a wide range of ISO holders and boring bars. Compatibility with a holder is determined by form, clearance angle, tolerance class, fastening method, size and thickness; matching these parameters ensures correct seat and clamping force, preventing movement during heavy cuts. Labelling and ISO coding facilitate straightforward replacement and inventory management in production environments.

Practical benefits in workshop applications and process reliability

As a universal turning grade intended for medium machining, this PVD-coated insert supports a wide material coverage and delivers stable chip formation under mixed cutting conditions, which reduces secondary operations and scrap. The insert suits both external and internal turning tasks where consistent results and tool-change simplicity are priorities. Paired with suitable coolant and holder rigidity, the geometry and coating help extend effective tool life and contribute to a more productive turning cycle with fewer interruptions.

FAQ

What materials is this insert intended for?
The VNMG160404-TM AH6225 is optimised for machining rostfreier Stahl and performs well across a broad range of stainless alloys thanks to its PVD-coated carbide grade.

Which operations suit this insert best?
This ISO rhombic insert is intended for external and internal turning; its geometry and chipbreaker suit medium machining where surface finish and process stability are required.

How does the TM chipbreaker affect machining?
The TM chipbreaker on the VNMG160404-TM AH6225 promotes controlled chip formation and evacuation, improving surface finish and reducing built-up edge during rostfreier Stahl turning.

What clutching and holder features are required for compatibility?
Compatibility is achieved when holder form, clearance angle, tolerance class, fastening method, size and thickness match the ISO insert; the cylindrical hole secures clamping in standard ISO holders.

What effect does the 0.4 mm corner radius have on results?
A 0.4 mm corner radius balances edge strength and finish quality, giving reliable tool life while enabling smooth finishes in medium turning applications with the AH6225 grade.
