CNMG 120404 NS9530 — CNMG120404 indexable turning insert by Tungaloy for turning (uncoated cermet, 0.4 mm radius)

A CNMG120404 NS9530 indexable turning insert optimised for fine finishing of steel, delivering a sharp cutting edge with reduced cutting forces and excellent surface quality.

• Uncoated cermet NS9530 for fine finishing
• Sharp cutting edge with low cutting forces
• Rhombic 80° geometry, 0.4 mm corner radius
• Double-sided with cylindrical centre hole

Outstanding surface quality for steel finishing

The uncoated cermet grade NS9530 is engineered for fine finishing of steel components, providing a consistently sharp edge that reduces rubbing and cutting forces during continuous cuts. As an ISO turning insert, this grade minimises built-up edge and helps achieve superior surface roughness with small depths of cut. The result is an efficient finishing process with fewer rework cycles and predictable part quality, especially in high-volume and precision environments.

Robust geometry and secure clamping for stable turning

The rhombic 80° form combined with a 0.4 mm radius and 4.76 mm thickness creates a stable cutting geometry that resists edge chipping under light to moderate loads. The insert is supplied with a cylindrical hole, permitting secure fastening and correct seating in ISO-compliant holders. Compatibility with a given toolholder depends on form, relief angle, tolerance class, attachment method, size and thickness, so selection of the correct holder and screw is essential for consistent performance.

Efficient production through double-sided design and chip control

The double-sided design effectively doubles the number of usable cutting edges, improving cost-efficiency per edge while simplifying inventory management. The integrated chipbreaker suited to finishing operations promotes predictable chip formation and evacuation, which supports uninterrupted turning cycles and reduces downtime. The insert’s Tungaloy engineering balances edge sharpness and wear resistance to provide repeatable results across batch production.

Recommended applications and tooling considerations

Designed primarily for external and internal turning, this indexable insert excels in continuous cutting and small feed operations where surface finish and dimensional control are priorities. Select a matching chipbreaker and grade according to workpiece stability and machining parameters; for less stable setups, opt for a more robust chip control geometry. Where necessary, pair the insert with a suitable ISO-format holder, underlay/clamp set and replacement screws to complete the system and ensure proper torque and seating.

FAQ

What materials is this insert best suited for? The NS9530 grade is optimised for finishing operations on steel; the CNMG120404 NS9530 insert provides a sharp edge and low cutting forces for improved surface quality on steel components.

How does the insert fix to the holder? The insert features a cylindrical centre hole for secure fastening; correct seating in an ISO-format holder is determined by form, relief angle, tolerance class, size and thickness.

Is the insert single- or double-sided? This CNMG120404 model is double-sided, offering two usable cutting edges per side and thus multiple indexing options to extend tool life.

Which chipbreaker should be chosen for finishing? A fine finishing chipbreaker matched to the NS9530 grade and the workpiece stability is recommended to ensure optimum surface finish and controlled chip formation.

Can the CNMG120404 NS9530 be used for internal turning? Yes, the insert is suitable for both external and internal turning operations, particularly in continuous cut scenarios and small depth-of-cut finishing tasks.
