SNMG 120404 NS9530 Indexable turning insert – Tungaloy

A SNMG120404 NS9530 ISO-series indexable insert for turning, optimised for finishing steel with a low cutting-force geometry and secure clamping.

• Uncoated cermet NS9530 for finishing
• Sharp cutting edge, low cutting forces
• Double-sided geometry, economical use
• 0.4 mm corner radius, square 12 mm form

Superior surface quality for finishing operations

The uncoated cermet grade NS9530 is engineered for finishing passes on steel, offering a sharp cutting edge that reduces cutting forces and promotes a fine surface finish on continuous cuts. For operations with small depths of cut the material’s inherent edge stability supports repeatable results and minimises workpiece rework. The combination of a low-relief angle and a precisely formed cutting edge helps achieve consistent dimensional accuracy without aggressive cutting parameters.

Cost-effective performance through indexability and geometry

A double-sided insert reduces tooling expenditure by providing two usable edges, while the square form and robust geometry ensure predictable wear patterns. The modest 0.4 mm corner radius delivers a balance between edge strength and the finer finishes expected in final passes, helping to lower total tooling cost per part. Where productivity and component quality must be weighed, this insert offers an economical choice that maintains finishing standards across medium-duty turning cycles.

Simple integration with ISO toolholders and secure clamping

Compatibility with standard ISO holders is determined by form, relief angle, tolerance class, fastening and thickness; the insert’s cylindrical hole and standard dimensions support reliable clamping in common outside holders and boring bars. The 4.76 mm thickness and square 12 mm form ensure mechanical stability in the holder assembly, while the 90° insert angle suits many turning set-ups for external and internal operations. Correct holder selection and torque for the clamping screw are decisive for runout control and repeatable machining.

Match chipbreaker and cutting data to application

The double-sided chipbreaker provides versatility across continuous finishing cuts; matching the chipbreaker style and insert grade to the workpiece and cutting conditions is essential for optimal chip control and surface integrity. For continuous cuts in steel, a finishing chipbreaker paired with the NS9530 grade keeps cutting forces low and surface roughness minimal. Where interrupted cuts or tougher materials are encountered, consider alternative grades or tailored chipbreaker geometries for stable performance.
