DNGG 150404 NS520 Turning Insert – Tungaloy, ISO rhombic insert for turning

DNGG150404 NS520 Tungaloy turning insert designed for finish to light turning operations on steel, offering a rhombic shape with a 55° included angle and a focus on reproducible surface finish and dimensional accuracy

• ISO 150404 rhombic insert
• NS520 cermet grade for fine finishing
• Double-sided with 0° clearance
• Cylindrical hole for secure clamping

Consistent finishing from a cermet grade built for surface quality

The NS520 cermet specification is developed for finish to light machining of steel, prioritising surface finish and dimensional stability. A cermet cutting material delivers reduced built-up edge and a stable cutting edge that helps achieve low roughness values on turned components. Selecting this grade and a suitable double-sided chipbreaker enables longer intervals between tool changes and more predictable tool life, which translates into fewer interruptions and higher part uniformity in serial production.

Geometry and mechanics engineered for stable turning results

The rhombic geometry with a 55° included angle and a corner radius of 0.4 mm provides a balance between cutting edge strength and fine finishing capability. The insert comes with a 0° clearance angle, a plate thickness of 4.76 mm and a cylindrical mounting hole, which together ensure secure clamping and rigidity in the toolholder. These features reduce vibration and support consistent chip formation when paired with an appropriate holder and clamping set. The double-sided design doubles usable edges, improving cost-efficiency while maintaining cutting stability.

System compatibility and practical application guidance

As an ISO-standard turning insert, compatibility with holders depends on form, relief angle, tolerance class, fastening method, size and thickness; therefore the ISO 150404 designation simplifies matching to standard external or internal turning holders. Typical use is external and internal turning; choose the double-sided chipbreaker and the NS520 grade according to workpiece material, machining strategy and machine rigidity. The recommended system comprises the ISO insert, a matching external holder or boring bar, an underlay/shim or clamp set and replacement screws to ensure secure mounting and repeatable set-up.

FAQ

What materials is this insert intended for?
The NS520 grade is specified for finish to light machining of steel and the insert is optimised for achieving good surface finish and dimensional accuracy with steel workpieces.

How does the DNGG150404 geometry affect cutting performance?
The rhombic 55° profile and 0.4 mm corner radius of the DNGG150404 insert support a balance of edge strength and fine finishing, producing stable cutting conditions and predictable wear during turning.

Is the insert reversible and how many cutting edges are available?
The double-sided design offers two usable cutting edges per side, increasing overall edge economy while maintaining the geometry needed for precise finishing.

Which holders are compatible with this ISO insert?
Compatibility follows ISO standards; holders must match the insert form, size, thickness, relief angle and fastening method—ensure the toolholder accepts ISO 150404 rhombic inserts and uses the cylindrical hole for secure clamping.

What is the manufacturer's article number and SKU for ordering?
Manufacturer article number is 6803196 and the manufacturer SKU is TUN6803196 for the DNGG150404 NS520 Tungaloy turning insert
