DNGG 150404 NS9530 turning indexable insert – Tungaloy, rhombic 15 mm, 0.4 mm nose radius

The DNGG150404 NS9530 is an ISO-standard rhombic turning insert designed for fine finishing and continuous cutting in steel applications.

• Uncoated cermet NS9530 for fine finishing
• Rhombic 15 mm geometry, 55° approach angle
• 0.4 mm nose radius for precision turning
• Double-sided design with cylindrical hole

Achieve consistent, high-quality surface finishes with low forces

The insert is manufactured in the NS9530 grade, an uncoated cermet optimised for finishing cuts on steel. The microstructure of this grade provides a sharp cutting edge and reduced built-up edge tendency, which translates into low cutting forces and improved tool life under continuous-cut conditions. For operations where surface integrity is paramount, the combination of cermet chemistry and the rhombic geometry reduces vibration and supports stable cuts, producing the consistent finishes demanded in high-value components.

Secure fitting and system compatibility for predictable productivity

Designed as an ISO-standard turning insert, the part fits a wide range of external holders and boring bars when form, clearance angle, tolerance class, fastening method, size and thickness align. The rhombic shape with a 55° approach angle offers versatility for external and internal turning; the cylindrical hole enables positive clamping and repeatable positioning. Integrating this insert into a matched tool system (holder, shim and clamping set) ensures predictable process behaviour and helps to reduce set-up time and scrap rates in production runs.

Material advantages and recommended cutting approach for steel finishing

With a 0.4 mm nose radius and a sharp, finishing-grade edge, the insert excels at small depth-of-cut passes and continuous feeds where surface quality is required. The grade’s wear characteristics are tuned for steel finishing: expect fine finishes at conventional speeds without the need for coatings. The double-sided concept gives economical edge utilisation, while the rhombic geometry supports light to moderate feed settings for improved dimensional control. If further machining data is needed for specific alloys or feed-speed windows, Metav Werkzeuge can supply application charts and recommendations.

FAQ

What materials is this insert intended for?
The DNGG150404 NS9530 Tungaloy indexable insert is formulated primarily for finishing of steel; the NS9530 cermet grade is optimised for continuous cuts and low cutting forces when machining steel.

How is the insert secured in the toolholder?
The part features a cylindrical hole for clamping; compatibility depends on holder form, clearance angle, tolerance class, fastening and plate thickness—ensure the holder matches the ISO geometry.

Can the insert be used for internal and external turning?
Yes, the rhombic 55° geometry and double-sided design make it suitable for both external and internal turning operations where a finishing edge is required.

What cutting conditions are recommended for best surface finish?
For the NS9530 grade, small depths of cut and continuous feeds at conventional finishing speeds yield the best high surface finish and tool life; consult Metav Werkzeuge for process windows for specific steels.

How many usable edges does the insert provide?
The insert is double-sided, offering economical edge changes and extended use before replacement is required.
