DNMG150612 NS9530 Tungaloy indexable insert for turning — cermet finishing grade, 55° rhombic

The DNMG150612 NS9530 is an ISO‑standard turning insert designed for finishing steel in continuous cuts, offering a low cutting force geometry and compatibility with common external holders and boring bars.

• DNMG150612 rhombic ISO insert, 55° cutting angle
• Uncoated cermet NS9530 for finishing steel
• 1.2 mm corner radius for superior surface finish
• Double-sided chipbreaker, with cylindrical hole

Consistent finishing with low cutting forces

The insert combines an uncoated cermet composition with the NS9530 grade to deliver stable, sharp cutting edges that are tailored for fine finishing on steel. Cermet materials offer reduced built‑up edge and improved wear behaviour at the cutting edge compared with some coated grades; this means a smoother surface on the workpiece and more predictable tool life during continuous turning. The low cutting forces inherent to the geometry reduce spindle load and can contribute to fewer re‑passes and less downstream polishing.

Predictable fit and secure clamping for stable turning

Compliance with ISO norms ensures the plate mates predictably with ISO‑specified holders; compatibility is determined by form, clearance angle, tolerance class, clamping method, size and thickness. The centrally placed, cylindrical hole and standard mounting interface support secure fixation in a matching seat and allow reliable repeatability when changing inserts. For workshop planners and production engineers, this means consistent part quality and fast insert exchange without costly adjustments.

Geometry engineered for surface quality and small depths of cut

The rhombic plate form with a 55° principal cutting angle, a 1.2 mm corner radius and a 6.35 mm thickness delivers a balance between edge strength and a fine contact geometry that is ideal for small depths of cut and continuous cuts. The double‑sided chipbreaker contributes to controlled chip formation and evacuation, which supports uninterrupted runs and reduces the risk of surface damage. In short, the geometry is optimised to produce excellent surface finishes while maintaining efficient material removal for finishing passes.

System integration and application guidance for process reliability

This insert is intended for turning applications, including external and internal operations, and forms part of a system comprising the ISO insert, a suitable external holder or boring bar, a shim or clamp set and replacement screws. Selection of the correct chipbreaker and grade should match the workpiece material and machining conditions; the NS9530 finishing sort is especially suited to steel when a sharp edge and low cutting forces are required. For process engineers planning tool layouts, the insert offers repeatable performance that supports predictable cycle times and consistent component quality.

FAQ

What materials is this insert intended for?
The DNMG150612 NS9530 insert is specified as a finishing sort for steel; the NS9530 cermet composition and sharp edge geometry favour continuous cuts on steel workpieces.

Can this insert be used for internal turning?
Yes, the ISO‑standard shape and secure clamping make the insert suitable for both external and internal turning applications when paired with an appropriate boring bar or holder.

How does the 1.2 mm corner radius affect the surface finish?
A 1.2 mm corner radius provides a favourable contact geometry for finishing, helping to produce a superior surface finish while maintaining sufficient edge strength for small depths of cut.

Is the insert reversible or single‑use?
This plate is double‑sided with a double‑sided chipbreaker, allowing it to be indexed to a fresh edge as defined by the ISO geometry until all usable edges are consumed.

What should be checked when selecting a compatible holder?
Compatibility depends on the plate form, clearance angle, tolerance class, clamping method, size and thickness; ensure the holder matches the ISO DNMG seat and provides correct support for the 6.35 mm thickness and cylindrical hole.
