VNMG160404-SS AH6225 (VNMG 160404) VNMG — Turning insert, 35°, Tungaloy

A VNMG160404-SS AH6225 ISO turning insert designed for external and internal turning of stainless steels with a sharp yet stable cutting edge for medium machining.

• PVD-coated carbide grade AH6225 for stainless steel
• 0.4 mm corner radius for precise chip control
• 35° cutting geometry for versatile turning
• Cylindrical hole for secure clamping

Consistent machining performance with a universal PVD-coated grade

The PVD-coated carbide grade AH6225 delivers a balance between sharpness and edge stability that suits variable cutting conditions encountered in stainless steel turning. The coating provides enhanced thermal resistance and wear protection, which translates into longer tool life and fewer interruptions for index changes. For medium- to general-purpose turning the combination of a sharp edge geometry and a robust substrate reduces the risk of built-up edge formation and supports reproducible surface quality. This makes the insert particularly useful in mixed-lot production where process stability and predictable tool wear are priorities.

Simple system fit and secure clamping for reliable repeatability

As an ISO-standard insert, compatibility with the toolholder depends on form, clearance angle, tolerance class, mounting method, size and thickness. The 16-size rhombic form, 4.76 mm plate thickness and 0.4 mm corner radius are engineered to fit common VNMG holders; the cylindrical hole ensures positive location and secure clamping, reducing vibration and promoting consistent cut geometry. Using the appropriate holder, shim or clamp set and the correct fastening screws completes a modular system that simplifies replacement and reduces machine downtime. For workshop planning, the standardised interface supports rapid changeover and repeatable set-ups across different lathes.

Practical guidance for application and chip control

The insert’s chipbreaker SS geometry and 35° rake/lead geometry are optimised for chip formation when machining stainless steels, helping to avoid long, stringy chips and to maintain coolant access to the cutting zone. A 0.4 mm corner radius offers a compromise between edge strength and the ability to produce fine contour details; smaller radii increase edge sharpness, larger radii improve robustness. As an indexable insert, it allows fast rotation to a fresh cutting edge, reducing maintenance time and improving process throughput. For customers seeking consistent results in turning operations, selecting the correct chipbreaker and cutting data in line with the material and machine rigidity will deliver repeatable part quality.

FAQ

What materials is this insert best suited for?
The VNMG160404-SS AH6225 is formulated for stainless steels, offering good chip control and surface finish in medium turning applications.

How does the AH6225 grade improve process reliability?
The AH6225 PVD-coated grade combines a sharp cutting edge with a wear-resistant coating to extend tool life and maintain stable cutting behaviour under variable conditions.

What does the 0.4 mm corner radius mean for part quality?
A 0.4 mm radius balances edge strength and the ability to produce fine features, supporting consistent surface quality while resisting edge chipping.

Is the insert compatible with my VNMG holders?
Compatibility depends on holder form, tolerance class, mounting and the insert’s size and thickness; the ISO-standard dimensions (size 16, thickness 4.76 mm) make it compatible with matching VNMG holders when the clearance angle and fastening match.

Can this insert be used for internal turning?
Yes, the geometry and chipbreaker allow use in both external and internal turning when paired with an appropriate boring bar or holder.
