High-quality finishing with low cutting forces

The DNMG150404 NS9530 is an ISO‑standard rhombic insert developed as a finishing grade for turning operations in steel. Manufactured from an uncoated cermet, the grade delivers a consistently sharp edge that reduces cutting forces and supports stable chip formation during continuous cuts. For production environments where surface integrity matters, the insert’s geometry and material composition are intended to produce an improved surface finish while maintaining tool life. The cermet substrate combines hardness with toughness, which enables lower built-up edge tendencies and a finer result on turned surfaces.

Economical, repeatable performance on double‑sided design

The two usable faces of this indexable insert increase tool utilisation and lower per‑cutting‑edge cost, while the central cylindrical hole and standardised form permit straightforward clamping in compatible holders. The 55° approach angle gives a balance between cutting force direction and component form control, and the 0.4 mm nose radius is suited to fine finishing where dimensional consistency is required. Because the insert conforms to ISO dimensions, selection of a matching external holder or boring bar is simplified; compatibility is determined by form, relief angle, tolerance class, fastening type, size and thickness, which are standardised to ease integration into existing tool systems.

Clear application range and material benefits

This grade is optimised for external and internal turning where small depths of cut and continuous feed are common. The NS9530 composition is especially effective on steels, combining repeatable edge integrity with good surface quality under stable cutting conditions. Technical setups that favour finishing cuts will benefit from reduced vibration sensitivity and predictable wear behaviour. For workshops evaluating cutting strategies, the cermet option is presented as a logical choice when prioritising surface quality and low cutting forces over heavy material removal rates.

FAQ

What cutting tasks is this insert best suited to? The NS9530 cermet grade insert is intended for finishing turning operations on steel, where continuous cuts and a sharp cutting edge deliver superior surface quality.

Can the insert be used in standard ISO holders? Yes, the DNMG150404 conforms to ISO dimensions; compatibility depends on holder form, relief angle, tolerance class, fastening type, size and thickness.

How does the double‑sided design affect productivity? A double‑sided insert allows two cutting edges per index, enhancing economical use and reducing downtime for edge changes.

What does the 0.4 mm nose radius mean for component finish? A 0.4 mm nose radius provides a fine balance between strength and detail in the turned profile, helping to achieve consistent surface finish for finishing cuts.

Is the NS9530 coated? The NS9530 grade is supplied as an uncoated cermet, optimised for sharp cutting performance and low cutting forces in finishing applications.
