DNGG150408 NS520 — DNGG 150408 cermet turning insert (55° rhombic) by Tungaloy

The DNGG150408 NS520 is an ISO‑standard indexable turning insert designed for finishing to light machining of steel, optimised for surface quality and repeatable dimensional accuracy.

• Cermet grade NS520 for fine surface finishes
• Rhombic 55° geometry for versatile turning
• 0.8 mm nose radius for precise profiles
• Double-sided chipbreaker for uniform chips

Achieving superior surface quality with a dedicated cermet grade

The NS520 grade is a cermet or coated cermet formulation developed for finishing and light cutting of steel, where surface finish and dimensional accuracy are priorities. Its composition combines the hardness and wear resistance of ceramic phases with the toughness of metallic binders, which reduces micro‑chipping and promotes even wear across cutting edges. As a result, process stability is improved and the need for touch‑up operations is reduced, delivering measurable gains in productivity and part quality.

Geometry and edge form engineered for reliable turning results

A rhombic 55° geometry with a 0° clearance angle provides a balanced cutting approach suitable for both external and internal turning tasks. The 0.8 mm nose radius supports small‑radius profiling while maintaining strength at the tip, enabling consistent contouring and repeatable part tolerances. The insert’s cylindrical hole and ISO conformity mean compatibility with a wide range of standard holders, with secure clamping ensured by correct seating, tolerance class and attachment type.

Process security and extended tool life through smart design

Constructed from carbide with the NS520 surface characteristics, the insert combines wear resistance with an emphasis on fine finishes. The double‑sided chipbreaker promotes predictable chip formation and evacuation, which reduces risk of built‑up edge and contributes to longer tool life. Stable chip control and uniform flank wear lower the frequency of index changes, supporting continuous production and improved overall equipment effectiveness.

Simple selection and integration for production environments

As an ISO‑specified indexable insert, integration into existing tool systems is straightforward: match holder geometry, free angle and thickness to the insert’s form and dimensions. The insert is primarily intended for turning applications on steel and is best paired with a chipbreaker and grade chosen for component rigidity and cutting parameters.
