VNMG160404-SF AH6225 ISO turning insert for Drehen — Tungaloy

A VNMG160404-SF AH6225 rhombic ISO turning insert, designed for external and internal turning, offering a sharp, stable cutting edge and PVD-coated carbide performance for stainless steel applications

• PVD-coated AH6225 grade for stainless steel
• 0.4 mm corner radius for smooth finishing
• SF chipbreaker for reliable chip control
• ISO rhombic shape with 35° geometry for stability

Consistent performance for stainless steel with reduced tool change

The PVD-coated AH6225 grade combines a sharp cutting edge and robust edge stability, making this insert well suited to variable cutting conditions in stainless steel. The coating improves wear resistance and promotes repeatable performance during medium turning tasks, so machining cycles are more predictable. Fewer tool changes and stable edge behaviour contribute to higher uptime and improved process efficiency, particularly in batch or mixed-production environments.

Geometry and chip control that stabilise cycle times

The insert’s rhombic form and 35° geometry reduce cutting forces and support consistent engagement during both external and internal turning. The SF chipbreaker is tailored to break and evacuate chips efficiently in medium cuts, lowering the risk of built-up edge and tool vibration. The presence of a cylindrical through-hole ensures secure fastening and repeatable clamping, which together help to maintain surface quality and dimensional consistency across production runs.

ISO compatibility and straightforward system integration

Designed as part of the ISO insert family, compatibility with holders depends on form, clearance angle, tolerance class, fastening method, size and thickness. The standardised dimensions simplify selection of a matching outer holder or boring bar, plus shim/clamp and replacement screws for secure mounting. This system approach reduces setup errors and shortens changeover times, supporting faster tool replacement and more reliable toolroom procedures.

Material and coating advantages for practical productivity gains

Made from sintered carbide and finished with a PVD coating, this insert balances wear resistance with cutting-edge sharpness—beneficial for achieving consistent surface finishes on stainless steel. The 0.4 mm corner radius and 4.76 mm thickness provide rigidity for medium cutting depths while allowing fine surface control where required. For operations needing a compromise between edge life and surface quality, this grade and geometry offer an economical, productive choice.

FAQ

Which materials is this insert intended for?
The VNMG160404-SF AH6225 insert (Tungaloy, SKU 6796317-Tungaloy) is specified for machining stainless steel and performs best in medium turning operations where edge stability and chip control are required.

What does the AH6225 grade offer?
AH6225 is a PVD-coated carbide grade developed for a balance of sharpness and edge robustness; in the VNMG160404-SF AH6225 it supports repeatable cutting performance across varying conditions.

How should the insert be mounted?
The insert is fixed through its cylindrical hole into a compatible ISO rhombic holder or boring bar; correct matching depends on form, clearance angle, tolerance class, fastening and thickness.

What cutting geometry improves finishing?
A smaller corner radius, such as the 0.4 mm on this insert, helps achieve smoother surface finishes while retaining sufficient edge strength for medium cuts with the VNMG160404-SF AH6225.

Is this insert suitable for internal turning?
Yes; the VNMG160404-SF AH6225 is designed for both external and internal turning, provided the chosen holder and overhang support the required rigidity.
