DNMG 150404 NS9530 Tungaloy insert – Uncoated cermet finishing grade for turning

DNMG150404 NS9530 Tungaloy-Wendeplatte is a rhombic, ISO-form insert designed for finishing turns on steel, offering a sharp cutting edge and low cutting forces

• DNMG geometry for versatile turning
• Uncoated cermet for fine finishing
• Sharp cutting edge for low cutting forces
• ISO 150404 with central hole for secure clamping

High-quality finishing with a specialised cermet grade

The NS9530 grade is an uncoated cermet formulated for finishing operations on steel, delivering a high surface finish with low cutting forces—advantages that translate into reduced rework and longer component life. In practice, cermet combines the wear resistance of ceramic phases with the toughness of metallic binders, which is why this grade performs particularly well in continuous cuts and when working with small depths of cut. The result is a consistent part surface and predictable tool behaviour, making the insert suitable for precision turning where surface integrity matters.

Secure clamping and ISO compatibility for repeatable results

The insert follows the ISO DNMG150404 form with a rhombic 55° geometry and a central cylindrical hole for clamping, ensuring reliable seating and repeatable positioning in standard holders. The plate thickness of 4.76 mm and a size designation of 15 provide robust support under finishing conditions, while the 0° clearance geometry supports neutral cutting engagements that favour small feed rates and smooth material flow. Together, these characteristics improve process stability and simplify tool changeovers in production environments.

Practical benefits for workshop productivity

As a finishing-grade indexable insert, this component reduces cycle variability and enables tighter tolerances with fewer passes. The sharp cutting edge of the NS9530 grade lowers cutting forces, which helps to limit workpiece distortion on thin-walled parts and improves machine loading. Using a double-sided chipbreaker and the proven geometry of this insert can lead to more predictable chip control and less manual intervention, supporting leaner workflows and higher throughput for turning applications in steel.

FAQ

What materials is this insert optimised for? The DNMG150404 NS9530 insert is optimised for finishing operations on steel, where its uncoated cermet grade delivers low cutting forces and a high surface finish.

Can the DNMG150404 be used in standard ISO holders? Yes, the insert conforms to the ISO DNMG150404 form and is compatible with standard holders that accept the 15-size rhombic insert with a central cylindrical hole.

What is the nose radius and how does it affect the surface finish? The nose radius is 0.4 mm; this modest radius supports fine surface finishes and precise dimensional control during finishing passes with small depths of cut.

Is the NS9530 grade suited to interrupted cuts? NS9530 is primarily a finishing grade intended for continuous cuts and small feed rates; its sharp edge and composition favour steady machining rather than heavily interrupted conditions.
