DNMG 150404 NS9530 ISO turning insert — finishing grade by Tungaloy

DNMG150404 NS9530 is an ISO-format indexable turning insert designed for finishing operations on steels, offering a sharp cutting edge and consistent surface quality in continuous cuts.

• Sharp NS9530 cermet grade for finishing
• 0° rake angle for low cutting forces
• 0.4 mm corner radius for fine surface finish
• Rhombic 15 mm form with cylindrical hole

Achieve consistent high-quality finishes on steel components

The NS9530 cermet grade is formulated as an uncoated finishing material that provides a sharp cutting edge and reduced cutting forces, making it especially suitable for continuous turning of steel. The improved edge geometry helps to lower vibration and heat generation, which directly benefits surface quality and repeatability in production. For workshops requiring predictable outcomes on finishing passes, this insert gives a reliable compromise between edge stability and low intrusion into the workpiece, resulting in fewer rework cycles and an efficient machining sequence.

Designed for dependable fit and predictable performance

The ISO designation and rhombic geometry ensure broad compatibility with ISO external holders and boring bars when the form, relief angle, tolerance class, clamping method, size and thickness are matched. The insert has a 0° rake angle and a 0.4 mm corner radius, features that deliver controllable chip formation and fine profile accuracy on small depths of cut. The central cylindrical hole secures the insert reliably to the seat using standard clamping sets and screws, reducing the risk of misalignment during high-speed finishing cycles. Choosing a holder with matching seat geometry and tolerance is essential to realise the full benefit of the insert’s geometry.

Practical application advice for production environments

Use the insert as a finishing grade for external and internal turning where low cutting forces and excellent surface finish are priorities. The double-sided chipbreaker design allows economical indexability, doubling the usable life per insert in many applications. For best results, pair the grade with stable setups and modest feed rates during final passes; this reduces cutting temperature and preserves the sharp edge. The product’s ISO format also simplifies inventory management across mixed toolrooms, enabling straightforward replacement and fewer adapter parts.

FAQ

What materials is this insert intended for?
The DNMG150404 NS9530 insert is specified as a finishing grade for steel and is optimised for continuous turning applications where a fine surface finish is required.

Is the insert coated or uncoated?
The NS9530 grade is an uncoated cermet designed to provide a sharp edge and low cutting forces in finishing operations.

How does the 0.4 mm corner radius affect the finish?
A 0.4 mm radius helps to produce a fine surface texture and reduces the tendency for edge chipping during light finishing cuts.

Can the insert be indexed to use multiple cutting edges?
Yes, the geometry and double-sided chipbreaker allow indexing to a fresh edge, effectively extending service life in routine turning tasks.

Which ISO holders will accept this insert?
The insert follows ISO dimensions for DNMG inserts; compatibility depends on matching form, relief angle, tolerance class, clamping method, size and thickness with the holder.
