VNMG160404 AH6225 Turning insert, PVD-coated carbide, 35° — Tungaloy

VNMG160404 AH6225 is an ISO rhombic, double-sided indexable insert optimised for external and internal turning of stainless steels under medium machining conditions.

• ISO rhombic VNMG form for versatile turning
• PVD-coated carbide AH6225 for stainless steels
• 35° approach angle with 0° clearance angle
• Double-sided chipbreaker, cylindrical hole for secure mounting

Stable, sharp cutting performance for stainless steels

The PVD-coated carbide grade AH6225 combines a finely tuned coating with a substrate designed for a sharp, yet durable cutting edge. This balance reduces built-up edge formation when machining stainless steels, improving surface finish and extending usable edge life. PVD (physical vapour deposition) provides a wear-resistant layer that lowers flank wear and supports consistent cutting forces in varying conditions. The result is improved process stability and predictable tool life in medium-duty turning applications.

ISO conformity for predictable clamping and quick tool changes

Designed as part of an ISO turning insert series, the insert matches established holder geometries by form, relief angle, tolerance class, fastening method, size and thickness. Clear compatibility criteria mean predictable clamping behaviour and minimal rework when replacing inserts. As part of a standard system, the insert works with a matched external holder or boring bar, a suitable shim/clamp set and replacement screws, which together reduce machine downtime and simplify stock management.

Reliable chip control and secure mounting in demanding conditions

The rhombic insert shape with a 35° approach angle and double-sided chipbreaker promotes controlled chip formation and evacuation, especially when the grade and chipbreaker choice are aligned to workpiece stability. The cylindrical hole allows secure fastening and accurate seat positioning, helping to maintain repeatable geometry and consistent contact between insert and holder. These design elements lower vibration risk and contribute to consistent surface quality during both external and internal turning.

Practical application advice for productivity and economy

For medium machining tasks and variable workpiece conditions, select the chipbreaker and grade that match the component material and machine rigidity; the AH6225 variety is a universal choice for stainless steels. Correct selection translates into fewer indexings, longer intervals between tool changes and better overall cost-efficiency. Where higher cutting speeds or different materials are required, assess grade and geometry options within the ISO insert family to maintain productivity without compromising finish or tool life.

FAQ

What materials is this insert suited for?
VNMG160404 AH6225 is formulated as a universal grade for stainless steels, providing good edge stability and wear resistance in medium machining operations.

What does the AH6225 grade offer compared with standard grades?
The AH6225 PVD-coated carbide offers a combination of a sharp cutting edge and increased coating endurance, which improves performance on stainless steels under varying cutting conditions.

How is the insert mounted and secured?
The insert features a cylindrical hole for secure fastening; compatibility with the holder depends on form, relief angle, tolerance class, fastening, size and thickness to ensure correct clamping.

Can the insert be used for internal as well as external turning?
Yes, the rhombic VNMG shape and double-sided configuration make the insert suitable for both external and internal turning tasks when matched to the correct holder and chipbreaker.

What measurable dimensions should be checked before selecting a holder?
Check the ISO designation (160404), insert size (16 mm), corner radius (0.4 mm) and the 35° approach angle to ensure the holder provides the correct seat and cutting geometry.
