DNMA 150404 NS520 Tungaloy indexable insert for turning, 55°

DNMA150404 NS520 Tungaloy insert for ISO‑standard external and internal turning applications, optimised for finishing and light machining of steel.

• ISO‑standard rhombic insert 55°
• Cermet NS520 for fine finishing
• Cylindrical hole for secure clamping

Consistent finishing and dimensional control with cermet technology

The cermet cutting grade NS520 is developed for finishing to light machining of steel where surface quality and dimensional stability are decisive. Thanks to the hard, wear‑resistant cermet substrate and tailored coating properties, the insert delivers a stable cutting edge and uniform wear, which promotes predictable component quality over serial production. For shops focusing on tight tolerances, the geometry helps reduce scatter in size and surface roughness; the result is fewer rework cycles and improved process reliability.

Secure mounting and geometry that supports versatile turning

The rhombic 55° geometry with a cylindrical locating hole ensures straightforward clamping in ISO‑compatible holders and helps maintain a predictable cutting direction for both external and internal operations. The insert’s 0° relief angle suits stable setups and light cuts where tool deflection must be minimised. When selecting a holder, match form, clearance angle, tolerance class, fastening method, size and thickness to the insert specification to ensure correct seating and repeatable performance; this system approach reduces vibration and supports finer surface finish.

Process recommendations and shop integration for efficient throughput

For productive machining, combine the DNMA150404 NS520 with a rigid toolpost and appropriate feed rates for finishing passes; the cermet grade responds well to moderate cutting speeds that emphasise surface integrity over heavy metal removal. Select a chipbreaker and grade variant aligned to the workpiece material and machine stability to keep chip control effective. For general workshop use, the insert suits operators seeking consistent geometric results and longer intervals between tool changes, contributing to lower overall machining costs and more stable production planning.

FAQ

What materials is this insert best suited for? The DNMA150404 NS520 Tungaloy insert is designed primarily for steel, with the NS520 cermet grade optimised for finishing and light machining where surface finish and dimensional control matter.

How does the 55° geometry affect cutting performance? A 55° rhombic geometry provides a compromise between strength and access: it allows good surface contact for finishing while enabling use in both external and internal turning applications when mounted in an ISO‑compatible holder.

Is the insert compatible with standard ISO turning holders? Compatibility depends on holder form, clearance angle and tolerance class; the insert follows the ISO standard series for indexable turning plates and requires a matching holder, clamp and screw for secure fixing.
