VNMG 120408 AH6225 — ISO indexable insert for turning by Tungaloy, PVD-coated carbide, 35° approach

VNMG120408E-SS AH6225 is an ISO-format turning insert designed for external and internal turning of stainless steel; rhombic form with cylindrical hole for secure clamping

• PVD-coated carbide AH6225 for stainless steel
• Rhombic ISO form with cylindrical hole
• 0.8 mm corner radius for robust edge control

Longer tool life through optimised grade and coating

The insert combines a PVD-coated surface with the AH6225 cutting grade to provide consistent wear resistance under varying conditions. The coating reduces adhesion and built-up edge when machining stainless steel, which translates into longer tool life and fewer interruptions for index changes. As a result, productivity is maintained without sacrificing surface quality, making the insert a cost-effective choice for medium turning operations.

Stable cutting performance and predictable surface finish

With a 0.8 mm corner radius and a 35° approach angle, the geometry delivers a reliable balance between edge strength and cutting sharpness. This stability supports controlled chip flow when paired with the SS chipbreaker style, helping to avoid vibration and achieve repeatable surface finishes. The design reduces the need for frequent regrinding and helps maintain process consistency across series production runs.

Secure seating and system compatibility for easy integration

The rhombic shape and cylindrical hole ensure secure clamping in a wide range of holders; compatibility is defined by form, clearance angle, tolerance class, fastening and plate thickness. The ISO designation and standard dimensions ease replacement and stocking; the insert fits typical external holders and boring bars used in general turning, reducing setup time and simplifying tool inventory management.

Practical selection guidance for shop-floor decisions

This grade is recommended for medium-duty turning of stainless steel where a sharp, yet stable, cutting edge is required. Select the SS chipbreaker and the AH6225 grade when an application demands improved chip control and balanced wear behaviour. The insert forms part of a system that includes the correct seat, clamp set and replacement screws, ensuring straightforward assembly and repeatable positioning for precision turning tasks.

FAQ

What materials is this insert best suited for?
The VNMG120408E-SS AH6225 insert is optimised for machining stainless steel and performs well under medium turning conditions.

What does the AH6225 grade offer in practice?
AH6225 provides a balanced combination of sharpness and edge stability; the PVD coating aids wear resistance and reduces adhesive wear when cutting stainless steel.

How does the SS chipbreaker affect chip control?
The SS chipbreaker is designed for controlled chip formation during turning, improving evacuation and reducing the risk of entanglement on rotating workpieces.

Which geometry features ensure secure clamping?
The rhombic form together with the cylindrical hole delivers positive seating and repeatable positioning in compatible ISO holders, aiding process stability.

Is this insert suitable for both external and internal turning?
Yes, the insert’s ISO format and geometry are suitable for both external and internal turning when used with the correct holder and clamping set.
