DNGG150402-01 NS520 Turning indexable insert (ISO 150402) for turning — Tungaloy

The DNGG150402-01 NS520 is an ISO‑standard rhombic turning insert designed for finishing to light machining of steel, engineered to deliver even wear, high surface quality and repeatable dimensional accuracy.

• ISO DNGG geometry, 55°
• NS520 cermet for finishing steel
• Cylindrical hole for secure clamping
• 0.2 mm corner radius for fine finish

High‑quality surface finish from a cermet grade

The NS520 grade is a cermet formulation optimised for finishing and light cutting of steel, combining ceramic hardness with a metallic binder to reduce built‑up edge and support a stable cutting edge. This composition promotes uniform wear and helps achieve consistent surface finish and dimensional accuracy on external and internal turning tasks. The insert's emphasis on fine machining makes it suitable where lower cutting forces and high visual quality of the workpiece are required.

Reliable system compatibility and secure clamping

Designed to the ISO DNGG form, the insert fits standard rhombic holders when matched for form, free clearance, tolerance class, fixation method, size and thickness. The 55° geometry and rhombic shape support versatile turning angles, while the cylindrical hole enables positive location and stable clamping in suitable clamping systems. A plate thickness of 4.76 mm and the ISO designation facilitate quick verification against existing toolholders and replacement stocks, reducing setup time and the risk of mismatch.

Practical machining advantages and selection guidance

A 0.2 mm corner radius is effective for finishing passes where profile fidelity and surface texture are priorities; the modest radius lowers cutting forces and helps maintain form accuracy. The insert is supplied with chipbreaker 01, which should be selected according to workpiece material, cutting parameters and machine stability to ensure controlled chip formation. For finishing steel, pairing the NS520 grade with modest feeds and appropriate speeds produces the best balance of life and surface quality. When selecting the complete system, consider holder rigidity and clamping torque to preserve the insert's performance and repeatability.
