DNMG 110404 NS9530 — Tungaloy indexable insert for Turning, rhombic, 0.4 mm radius

The DNMG110404 NS9530 is an ISO-standard rhombic indexable insert designed for external and internal turning applications, optimised as a finishing grade for steel with a sharp cutting edge and low cutting forces

• NS9530 cermet for high surface finish
• Sharp edge for low cutting forces
• Double-sided chipbreaker design
• ISO DNMG 110404, rhombic, 0.4 mm radius

Consistent finishing performance for steel components

The uncoated NS9530 cermet grade is engineered for finishing operations where high surface finish and dimensional accuracy are priorities. Its sharp cutting edge reduces ploughing and produces lower cutting forces, which is particularly beneficial for continuous cuts and small depths of cut. For turning operations this means improved surface integrity and fewer rework steps, helping to shorten cycle times while maintaining consistent part quality.

Geometry and ISO compatibility for secure toolholding

The rhombic DNMG110404 geometry with a 0.4 mm corner radius and a 55° wedge angle provides predictable chip formation and stable cutting when paired with the correct holder. Compatibility to the toolholder is determined by form, clearance angle (0°), tolerance class, fastening method, size and thickness; ensuring the insert seats correctly prevents chatter and enhances repeatability. The ISO standardisation allows straightforward replacement within established turning tool systems.

Chip control and economical indexing

A double-sided chipbreaker layout enables indexing to a fresh cutting edge, extending the effective life per insert and reducing tooling costs per component. The chipbreaker design supports controlled chip flow and heat dissipation during finishing cuts, lowering thermal load on the edge and sustaining the fine cutting geometry. These attributes contribute to stable process windows and fewer interruptions for tool changes in production environments.

Selection advice and application notes for process reliability

Select the NS9530 finishing grade when machining steels where low cutting forces and surface quality are required; pair the insert with a holder suited to rhombic DNMG geometry and ensure clamping and tolerance class match. For mixed or less rigid setups, consider a more robust grade or adjusted cutting data. If uncertainty remains about the ideal chipbreaker or parameter set for a specific alloy and machine condition, Metav Werkzeuge provides application support and can advise on optimal combinations to achieve repeatable, economical machining.

FAQ

What steels is this insert best suited for?
The NS9530 uncoated cermet grade is optimised for finishing steels; the DNMG110404 insert delivers low cutting forces and a fine surface finish in continuous turning operations.

Can the insert be used on internal turning as well as external turning?
Yes, the ISO rhombic geometry and DNMG110404 designation make the insert suitable for both external and internal turning when used with a compatible holder.

How does the double-sided chipbreaker affect tool life?
A double-sided chipbreaker allows indexing to a fresh edge, effectively doubling the available cutting edges per insert and improving cost efficiency for finishing cycles.

What should be checked for holder compatibility?
Ensure the holder matches the insert form, clearance angle (0°), tolerance class, fastening method, size and thickness to guarantee proper seating and repeatable performance.

Is the insert coated?
This insert is an uncoated cermet grade (NS9530), specifically intended for finishing applications where a sharp edge and low cutting forces are required.
