Consistent surface quality for finishing operations

The NS9530 grade is a finishing cermet developed to deliver superior surface integrity when machining steel. Its uncoated composition provides a very sharp cutting edge, which reduces cutting forces and minimises built‑up edge formation during continuous cutting. The result is a predictable surface finish and reduced need for secondary processes. For applications where small depths of cut and fine tolerances are the focus, this specification supports stable, repeatable performance.

Geometry that supports process stability and flexibility

With an 80° included angle and a 0.4 mm corner radius, the plate geometry balances strength and edge finesse. The 11° rake angle lowers shear forces, improving chip formation and reducing vibration in finishing passes. The rhombic plate shape and standard ISO sizing allow straightforward integration into common holders and boring bars; compatibility is governed by form, relief angle, tolerance class, fixing method, size and thickness, which together ensure correct seating and clamping in the toolholder.

Material and chip control explained for practical use

The cutting material is uncoated cermet, chosen for its ability to produce fine surface textures on steel while maintaining a sharp edge at lower cutting depths. A single‑sided chipbreaker is provided to support controlled chip formation in continuous cuts, limiting entanglement and heat concentration. For operators transitioning from coated grades, the cermet’s behaviour offers a clear advantage in finishing cycles where low cutting forces and excellent surface finish are priorities.

Integration into a reliable system for efficient turning

The insert is supplied in the ISO series format and functions as part of a system comprising a suitable external holder or boring bar, shim/clamping set and replacement screws. The plate includes a cylindrical hole with a single‑side countersink (40°–60°) for secure fastening and repeatable positioning. The 3.18 mm plate thickness and ISO dimensioning simplify logistics and tool inventory management, enabling faster set‑ups and fewer process interruptions.
