DNMG150408 NS520 Tungaloy indexable insert for turning

A DNMG150408 NS520 indexable insert designed for finishing and light turning operations on steel, offering a rhombic geometry and robust chip control.

• Cermet grade NS520 for finishing
• ISO DNMG150408 rhombic geometry
• Double-sided chipbreaker for stable chips
• Cylindrical hole for secure clamping

Superior surface quality through cermet technology

The NS520 grade is a cermet developed for finishing to light machining of steel, combining high hot hardness with a metallurgical binder to deliver excellent surface finish and dimensional stability. Cermets produce finer, more uniform wear than standard carbide in low-to-medium cutting speeds, which helps to maintain tolerance and reduce rework. For engineers seeking consistent part quality, the fine-grained cutting edge of this insert reduces the tendency for built-up edge and supports predictable cycle times.

ISO compatibility and secure clamping for reliable production

The insert follows ISO geometry and is designated DNMG150408, which simplifies integration into standard indexable tooling systems. Key dimensional attributes such as the 15 mm size, 4.76 mm thickness and a cylindrical hole enable reliable seating and repeatable clamping in matched holders. Compatibility is determined by form, clearance, tolerance class, fastening and size; selecting a holder that matches these parameters ensures repeatable positioning and reduces vibration, supporting stable cutting conditions and fewer rejected parts.

Stable chip control and longer tool life

Equipped with a double-sided chipbreaker, this insert controls chip formation across both indexable edges to promote steady evacuation and reduced risk of chip re-cutting. The chipbreaker geometry, combined with the wear characteristics of the cermet grade, yields consistent wear and predictable edge life in finishing cuts. The result is less downtime for insert changes and more predictable maintenance planning, which benefits batch production and quality-focused operations.

Practical selection and process impact

The 0° rake angle and a corner radius of 0.8 mm make the insert well suited to finishing feeds that prioritise surface integrity and edge strength. When selecting the chipbreaker and grade, match the NS520 to workpiece material, feed rate and machine stability to exploit its strengths in surface quality and even wear. The complete system comprises the ISO insert, a compatible external holder or boring bar, a shim/clamping set and replacement screws — ensuring that the mechanical stack-up is stable for precision turning.

FAQ

What materials is this insert intended for?
The DNMG150408 NS520 insert is specified for finishing and light machining of steel, with the cermet grade optimised for surface quality and even wear.

Is the insert indexable on both sides?
Yes; the DNMG150408 is double-sided and can be indexed to present a fresh cutting edge, extending service life and reducing tooling costs.

How does the chipbreaker affect performance?
The double-sided chipbreaker promotes stable chip formation and evacuation, improving surface finish and reducing the risk of chip-related interruptions during turning.

Which holders are compatible with this ISO insert?
Compatibility depends on matching the ISO form, clearance, tolerance class, fastening method, size and thickness; use a holder designed for DNMG150408 geometry for secure clamping and repeatable positioning.

What does the corner radius of 0.8 mm mean for machining?
A 0.8 mm corner radius balances edge strength with the ability to achieve fine surface finishes; it suits finishing feeds while maintaining robustness against minor interruptions.
