CNMG120408 NS9530 Tungaloy – ISO turning indexable insert for fine finishing

CNMG120408 NS9530 Tungaloy is an ISO‑standard rhombic insert designed for external and internal turning, offering a finishing‑grade cermet for steels.

• ISO rhombic CNMG insert, proven form
• Uncoated cermet NS9530 for fine finishing
• 0.8 mm corner radius for smooth surfaces
• Double-sided chipbreaker with cylindrical hole

Enhanced surface quality with a finishing cermet

The NS9530 grade is an uncoated cermet formulated for finishing operations in steel, delivering a sharp cutting edge and low cutting forces. This composition minimises built‑up edge and supports continuous cutting with small depths of cut, resulting in consistent surface quality and reduced rework. The modest 0.8 mm corner radius helps to produce clean transitions on external profiles while limiting vibration at modest feedrates.

Clear compatibility and straightforward mounting

Being an ISO insert of the CNMG form, interchangeability with compatible holders is straightforward when matching the insert form, rake angle, tolerance class, fastening method, size and thickness. The plate has a 0° rake angle and an 80° included angle, and it comes with a cylindrical hole for secure attachment. These defined dimensions simplify toolholder selection and setup, reducing machine downtime during tool changes and ensuring repeatable assembly.

Productive finishing under stable conditions

The rhombic geometry combined with a double-sided chipbreaker enables two cutting edges per index, supporting economical tool usage and predictable wear behaviour. For applications requiring high surface integrity and predictable edge life, this insert provides a balance between sharpness and robustness. As a factory original from Tungaloy, the insert is suited to methodical turning tasks where consistent results and good edge stability are priorities.

FAQ

What materials is this insert intended for?
The CNMG120408 NS9530 insert is a finishing grade intended primarily for use on steel; the NS9530 cermet excels in continuous cutting and small depths of cut where surface finish is the priority.

Is the insert reversible and how many cutting edges are available?
The plate features a double‑sided chipbreaker, providing two usable cutting edges per index to maximise economy in production.

Which holder features must match the insert?
Compatibility is defined by the insert form, 0° rake angle, tolerance class, fastening method, 12 mm plate size and 4.76 mm thickness; matching these attributes ensures correct seating and clamping.

Does the insert have a mounting hole and what type is it?
Yes, the insert is supplied with a cylindrical hole, designed for secure fastening in standard CNMG holders.

What surface quality can be expected when using this grade?
When used as a finishing insert with appropriate feeds and small depths of cut, the NS9530 cermet produces a high surface finish with low cutting forces and minimal built‑up edge.
