CNMG 120404 NS9530 Turning Insert (Finishing) — Tungaloy

A CNMG 120404 NS9530 Tungaloy turning insert designed for precision finishing of steel, offering a sharp edge and low cutting forces for superior surface quality

• Uncoated cermet NS9530 for finishing
• Sharp edge with low cutting forces
• ISO CNMG120404 rhombic 80° form
• Compatible with cylindrical-hole clamping

Consistent finishing with a low-force cutting geometry

The NS9530 grade is an uncoated cermet developed for finishing operations on steel. Its chemistry and microstructure combine wear resistance with a cutting geometry that delivers a high surface finish while keeping low cutting forces, which reduces chatter and improves dimensional stability on long workpieces. For continuous cuts and small depth passes the material pairing is particularly efficient: the cermet edge maintains sharpness longer than conventional grades, so the process yields consistent part quality over longer tool life. The result is a reduction in rework and downstream polishing time from the first pass.

Reliable fit, ISO conformity and clear geometry for easy integration

This indexable insert is made to the ISO CNMG120404 form — a rhombic shape with an 80° approach angle — and features a 0° rake angle, giving a predictable cutting direction and contact point for standard external and internal turning holders. The insert is supplied with a cylindrical hole, so compatibility with a clamping system depends on the holder’s shape, clearance angle, tolerance class, fastening method, size and thickness. Specifying an ISO-compliant insert simplifies tool selection and changeover in mixed-machine environments, enabling faster set-up and reliable repeatability across multiple machines.

Practical application: choose the chipbreaker and setup for best results

Designed as a finishing grade, the insert pairs best with small radial depths and steady feedrates; its double-sided chipbreaker supports stable chip control in continuous turning and helps maintain surface integrity. For steels where built-up edge could occur, the sharp cermet edge minimises adhesion and preserves the required finish. When machining less stable setups or interrupted cuts, selecting a more robust chipformer and adjusting feeds can extend life. For complex or unfamiliar applications, the combination of grade, chipbreaker and holder geometry can be reviewed with a tooling specialist to match process stability and the desired surface specification.

FAQ

Is this insert suitable for finishing steel? This CNMG 120404 NS9530 Tungaloy turning insert (SKU TUN6707284) is optimised as a finishing grade for steel, offering a sharp edge and low cutting forces for high surface quality on continuous cuts.

Which holder features determine compatibility with the insert? Compatibility is governed by holder form, clearance angle, tolerance class, fastening method, size and thickness; the cylindrical-hole clamping must match the insert’s geometry for secure fixation.

Can the insert be used for internal as well as external turning? Yes, the geometry and rhombic form make it suitable for both external and internal turning when the correct holder and approach are selected; ideal results are achieved with steady feeds and small depths of cut.

Is the cutting edge coated or uncoated? The grade is an uncoated cermet (NS9530), chosen to provide a very sharp, wear-resistant edge for finishing; coated alternatives are available in other grades if coating is required for specific applications.

How does the double-sided chipbreaker affect use and indexing? A double-sided chipbreaker provides stable chip control in two orientations and supports the intended finishing feeds; indexing strategy depends on the insert’s geometry and the clamping system used.
