Achieve superior surface quality with a finishing-grade cermet

The NS9530 grade is an uncoated cermet developed for finish turning of steel, delivering low cutting forces and a consistently fine surface finish. Cermet combines ceramic and metallic properties, so it keeps a sharp cutting edge longer under continuous cutting conditions; this reduces the tendency for built-up edge and helps to maintain dimensional accuracy. For customers aiming for smooth part surfaces and predictable process behaviour, the finishing orientation of this grade means fewer downstream operations and a more stable machining cycle.

ISO compatibility and geometry that simplify process planning

Built to ISO geometry, the rhombic design with a 55° approach angle and 0° clearance provides a familiar reference for holder selection and programme setup. Compatibility with a chosen holder depends on insert form, clearance angle, tolerance class, fixing method, size and thickness; this ISO conformity simplifies cross-referencing with existing toolholders and reduces setup times. The standardised format also supports reproducible results across machines, enabling easier process qualification and repeatable component quality in production runs.

Controlled chips and steady cutting for continuous operations

The double-sided chipbreaker manages chip formation during low-depth finishing cuts, improving evacuation and reducing the risk of surface marks. Combined with the cermet’s low cutting resistance, the insert promotes steady-state cutting in continuous-feed applications, which means less vibration, improved surface integrity and more reliable cycle times. Explaining the chipbreaker: it shapes and breaks the chip as it forms, thereby avoiding long, entangling chips and facilitating automated or high-volume production.

Practical specifications that aid selection and installation

Key physical details support correct selection: the insert features a 0.4 mm corner radius, a plate thickness of 4.76 mm and a cylindrical hole for secure clamping. The carbide substrate provides structural strength while the uncoated surface of this finishing grade focuses on edge sharpness rather than extreme wear resistance, making it ideal for light, high-quality finishing passes. The system typically comprises the ISO insert, a matching external holder or boring bar, a shim/clamp set and replacement clamping screws — select the chipbreaker and grade that match the workpiece material and the rigidity of the setup.

FAQ

Which materials is this insert suitable for?
The DNMG110404 NS9530 Tungaloy insert is intended primarily for finishing of steel; the NS9530 uncoated cermet is optimised for low cutting forces and superior surface finish on steel workpieces.

How does the 0.4 mm corner radius affect machining?
A 0.4 mm corner radius provides a balance between edge strength and surface quality; with the DNMG110404 NS9530 this radius helps to maintain a sharp profile for fine finishing passes while still offering sufficient robustness against minor deflections.

Can the insert be used on both sides?
Yes, the insert is double-sided and includes a double-sided chipbreaker, allowing the insert to be indexed and reused on the second cutting edge to extend usable life.

What holder characteristics must be matched to this insert?
Compatibility requires matching the insert form, clearance angle (0°), tolerance class, fixing method, size and thickness; choose a holder or boring bar specified for DNMG geometry to ensure correct clamping and cutting attitude.

How does the chipbreaker support continuous cuts?
The double-sided chipbreaker actively shapes and breaks chips during the cut, reducing long, continuous swarf and enabling stable chip evacuation, which is particularly beneficial for continuous-feed finishing operations.
