DNGA150408 NS520 Tungaloy turning insert — rhombic 55° geometry, cermet grade for finishing

DNGA150408 NS520 Tungaloy-Wendeplatte is an ISO rhombic insert designed for external and internal turning, optimised for finishing and light machining of steel

• DNGA geometry with 55° cutting angle
• Cermet grade NS520 for superior surface finish
• ISO compatibility; fits holders with cylindrical hole

Achieve consistent surface quality and dimensional control

The NS520 grade is a cermet formulation developed for finishing to light machining of steel, prioritising surface finish and dimensional accuracy. The combination of a wear-resistant substrate and an engineered coating delivers even flank and nose wear, which reduces the need for frequent rework and keeps tolerances stable across runs. In practice, this means fewer rejects and a higher first-pass yield when precision and visual surface quality are critical.

Designed for straightforward integration into ISO tool systems

The insert follows ISO standards so compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness. The rhombic shape with a 55° cutting angle and a 0° clearance specification suits many external and internal turning set-ups. The cylindrical hole and the 4.76 mm plate thickness allow secure clamping in common holder systems; a matching shim or clamp set and replacement screws complete the system. This clarity reduces setup time and supports stable, repeatable machining.

Cermet characteristics and practical machining guidance

Cermet grades such as NS520 combine the hardness of ceramics with the toughness of a metallic binder, giving a cutting edge that excels in fine finishing operations. The substrate is effectively a form of carbide optimised for low built-up edge and consistent wear behaviour. For best results in finishing, maintain moderate cutting speeds and light feeds, monitor tool life visually for even wear progression, and choose a holder that minimises vibration. The insert is supplied without a chipbreaker, so matching the grade and geometry to the workpiece material and machining stability is essential for chip control.
