VNGG160402-01 NS520 — ISO turning insert, cermet grade for finishing, Tungaloy

A VNGG160402-01 NS520 is an ISO-standard rhombic turning insert engineered for finishing to light turning of steel, focusing on surface quality and dimensional stability.

• NS520 cermet for superior surface finish
• Rhombic shape with 35° cutting angle
• 0.2 mm corner radius for fine detail
• Cylindrical hole and secure ISO clamping

Precision finish and material interaction for reliable results

The NS520 grade is a cermet specification optimised for finishing and light machining of steel, delivering high-quality surfaces and consistent tool wear. Cermet combines ceramic hardness with controlled metal toughness; this balance reduces built-up edge and improves dimensional repeatability in finishing cuts. For operations where surface integrity and tight tolerances matter, the cermet behaviour of this insert supports reduced rework and predictable component conformity. Selection of the correct chipbreaker and grade ensures the desired balance between surface finish and tool life.

Secure clamping and ISO compatibility reduce set-up risk

Built to ISO geometries, the rhombic plate and its cylindrical hole secure reliably in standard holders; compatibility is determined by form, relief angle, tolerance class, fastening method, size and thickness. The 35° approach angle promotes stable cutting forces during external and internal turning, while the 0° relief angle minimises cutting edge interference on finishing passes. Where machine rigidity and holder design are limiting factors, the standardised geometry simplifies insert exchange and keeps downtimes short, supporting consistent production flow.

Operational advantages and recommended application practice

The modest 0.2 mm corner radius and the 01 chipbreaker suit finishing and light machining, enabling finer surface structure and reduced vibration sensitivity in short-turn or light-roughing passes. The 4.76 mm plate thickness contributes to edge strength while the rhombic shape facilitates multiple indexed edges per insert, improving economics per part. For best results, pair the insert with a matching external holder and choose a chipbreaker and grade aligned with workpiece stability and feed rates; this approach extends edge life and enhances overall productivity.

FAQ

What materials is this insert suitable for?
The NS520-grade insert is specified for finishing to light turning of steel; the VNGG160402-01 NS520 excels where surface quality and dimensional accuracy are priorities.

How is compatibility with a toolholder determined?
Compatibility depends on ISO geometry, relief angle, tolerance class, fastening method, plate size and thickness; the rhombic form and cylindrical hole match standard ISO clamping systems.

Which processes benefit most from this insert?
Finishing and light machining operations benefit most, as the 0.2 mm corner radius and cermet grade favour fine surface finishes and even wear.

Can the insert be indexed multiple times?
Yes, the rhombic shape provides multiple usable cutting edges; indexing extends the effective life per insert and supports economical production.

Is this insert suitable for internal turning?
The geometry and chipbreaker selection make the insert usable for both external and internal turning when paired with an appropriate holder and machining setup.
