CNMG 090404 NS9530 Tungaloy turning insert — ISO CNMG finishing grade

A CNMG090404 NS9530 Tungaloy insert designed for precision external and internal turning, optimised as a finishing grade for steel.

• ISO CNMG geometry, 80° cutting angle
• NS9530 uncoated cermet finishing grade
• 0.4 mm corner radius for fine surfaces
• Double-sided chipbreaker, cylindrical hole

Precision finishing with low cutting forces

The combination of the NS9530 uncoated cermet grade and CNMG geometry was developed for finishing operations on steel, delivering a noticeably improved surface quality at low feed rates. As a cermet, the cutting material offers a higher hardness and heat resistance than conventional carbides while maintaining a fine, sharp edge for continuous cuts and small depths of cut. This results in reduced cutting forces and less tendency for built-up edge formation, which supports consistent dimensional accuracy and repeatable surface roughness on turned components.

Reliable clamping and ISO compatibility for stable turning

ISO standardisation ensures predictable fitment in industry-standard holders, but compatibility depends on multiple parameters such as form, relief angle, tolerance class, fastening method, size and plate thickness. The rhombic CNMG shape with an 80° cutting angle, 0° relief and a plate thickness of 4.76 mm offers a robust seating for stable cutting, while the cylindrical hole facilitates secure clamping and simple indexation. The double-sided design provides two usable cutting edges per side, extending runtime before indexation and reducing tool change frequency in a production environment.

Consistent productivity and surface finish in serial production

The double-sided chipbreaker and the small 0.4 mm corner radius support fine finishing cycles, enabling predictable removal rates and consistent part-to-part quality. For continuous turning on steels, the uncoated cermet grade reduces vibration sensitivity and tends to produce a superior optical finish compared with industrial coated grades in the same application window. Selection of the correct chipbreaker and grade according to component stability and machining conditions is essential; the combination of NS9530 and the CNMG form enhances process reliability and helps shorten downstream finishing or grinding operations.

FAQ

Which materials is this insert best suited for? The CNMG090404 NS9530 insert is formulated as a finishing grade for steel; the NS9530 uncoated cermet performs particularly well in continuous cuts and small depths of cut on steel alloys.

Can the insert be used for both external and internal turning? Yes. The geometry and the 80° lead angle make the insert suitable for both external and internal turning operations when paired with a compatible ISO holder.

How is holder compatibility determined? Compatibility is governed by the insert form, relief (free) angle, tolerance class, fastening method, size and thickness — the CNMG090404 follows ISO conventions for predictable fitment in standard external holders and boring bars.

Is the insert indexable, and how many edges are available? The insert is double-sided with a chipbreaker on each side, providing multiple usable cutting edges before discarding or reconditioning.

What are the main benefits of the NS9530 grade compared with coated carbides? NS9530 as an uncoated cermet offers a finer cutting edge and improved heat resistance for finishing work, often producing better surface quality and lower cutting forces in the intended application range.
