CNMG 120404 NS9530 Tungaloy indexable insert – precision turning, uncoated cermet

The CNMG120404 NS9530 is an ISO-standard indexable insert for turning, engineered as a finishing grade for steels with a sharp cutting edge and consistently high surface quality

• ISO-standard CNMG 120404 geometry
• NS9530 uncoated cermet for fine finishing
• Double-sided chipbreaker, cylindrical hole
• Low cutting forces and high surface finish

Consistent fine finishing for steel turning

The NS9530 grade is an uncoated cermet developed for finishing operations on steels, offering a sharp cutting edge and reduced friction at the tool–workpiece interface. The grade promotes low cutting forces, which helps to lower vibration and improves dimensional stability during continuous cuts and small depths of cut. As a result, operators can expect an improved surface finish and reduced need for secondary machining when this finishing insert is applied in the correct cutting window.

ISO compatibility for predictable tool set-up

Built to ISO geometry, the insert ensures predictable fitting and repeatable clamping with compatible holders. Key geometric parameters such as the 0° clearance, the 80° approach angle, the rhombic plate form and the plate thickness of 4.76 mm determine compatibility with a wide range of external holders and boring bars. Because holder compatibility is defined by form, clearance angle, tolerance class, fastening method, size and thickness, the ISO specification simplifies tool changeovers and supports a standardised tool inventory across the shop floor.

Reduced downtime through double-sided productivity

The double-sided chipbreaker offers multiple usable edges, effectively extending time between indexings and lowering tooling costs per part. The cylindrical hole provides reliable location and secure clamping, contributing to stable chip formation and repeatable machining results. For finishing cuts, the combination of the NS9530 substrate and the dedicated chip control geometry supports productive machining, particularly when small feeds and light depths of cut are used to achieve the target surface quality.

FAQ

What workpiece materials is this insert intended for? The CNMG120404 NS9530 Tungaloy indexable insert is specified as a finishing grade for steels; the NS9530 cermet provides the edge geometry and low cutting forces suited to continuous finishing passes on steel components.

Is the insert reversible and how many edges are usable? Thanks to the double-sided chipbreaker and the rhombic plate form, multiple cutting edges are available; the design allows indexing for extended tool life and consistent results.

How is compatibility with holders ensured? Compatibility is determined by ISO geometry—form, clearance angle, tolerance class, fastening, size and thickness—so holders matching CNMG 120404 geometry provide correct seating and clamping.

What edge radius is recommended for fine finishing? A corner radius of 0.4 mm suits fine finishing where excellent surface quality is required; matching feed and depth of cut to the radius will preserve the sharp edge performance.

Is the insert coated? The NS9530 grade in this insert is uncoated cermet, selected for its sharp edge and low cutting resistance in finishing applications on steel.
