CNGG 120404 NS9530 CNGG turning indexable insert by Tungaloy — ISO finishing insert, 80° geometry

The CNGG120404 NS9530 is an ISO-standard indexable insert designed for precision external and internal turning, optimised for fine finishing on steel components.

• Cermet grade NS9530 for high surface quality
• ISO CNGG 120404 rhombic insert, 80° geometry
• 0° clearance, 0.4 mm corner radius, 4.76 mm thick
• Double-sided chipbreaker with cylindrical hole

Consistent finishing with low cutting forces

The uncoated cermet NS9530 is formulated for finishing operations on steel, delivering a high surface quality with low cutting forces during continuous cuts and small depth-of-cut applications. Cermet combines ceramic hardness with metallic toughness, which helps maintain a sharp cutting edge longer than many alternatives in fine-turning scenarios. This results in fewer passes to reach tolerance, reduced rework and a measurable improvement in cycle consistency. The grade is especially suitable where a fine surface and tight dimensional control are primary goals.

Secure seating and reliable repeatability in the tool system

Built to the ISO CNGG 120404 form, the insert's 80° geometry and rhombic shape allow secure clamping in standard holders. The 0° clearance and a 0.4 mm corner radius work together to lower radial cutting loads and improve stability when machining small stepovers or finishing shoulders. The insert is supplied with a cylindrical hole for positive locating and a double-sided chipbreaker that enables reversible use for cost-effective tool life. Where setup repeatability and predictable cutting behaviour are required, this geometry reduces the need for frequent adjustments and shortens machine downtime between tool changes.

Practical application guidance for process reliability

The insert is intended for turning applications on steel workpieces and is recommended for continuous cuts with small material removals. Compatibility with a holder depends on form, clearance angle, tolerance class, clamping method, size and thickness; pairing the insert with the correct external holder and clamping set ensures the expected performance. The system approach—insert, holder, backing pad and fasteners—supports rapid changeovers and consistent clamping force, which in turn improves repeatable part quality. For best results, select the chipbreaker and grade according to workpiece stability and machining parameters; this approach extends productive cutting time and supports efficient process planning.

FAQ

What materials is this insert best suited for? The CNGG120404 NS9530 insert is specified as a finishing grade for steel; the NS9530 cermet composition is optimised for producing fine surface finishes on steel workpieces.

Can the insert be used on both external and internal turning operations? Yes, the ISO CNGG 120404 form is suitable for both external and internal turning when paired with the appropriate external holder or boring bar.

How does the 0° clearance affect cutting performance? A 0° clearance reduces the clearance angle to favour low cutting forces and a true finishing action; in practice this supports better surface finish and stable tool engagement during small-depth cuts.

Is the insert reversible and cost-effective for production use? The double-sided chipbreaker allows the insert to be rotated for a second cutting edge, providing cost-effective usage and predictable performance across cycles.

Which components are required to assemble a complete cutting system? A complete system consists of the ISO insert, a matching external holder or boring bar, a backing/locking pad or clamping set, and the appropriate fasteners—this ensures correct seating and reliable repeatability in production.
