DNMG150404 NS9530 — ISO turning insert for finishing by Tungaloy

DNMG150404 NS9530 is a Tungaloy ISO-standard rhombic turning insert designed for finishing operations on steel, offering a sharp cutting edge and low cutting forces.

ISO‑standard rhombic insert Cermet grade NS9530 for finishing Sharp cutting edge for low cutting forces Double-sided chipbreaker with cylindrical hole

Consistent finishing and reduced rework through a dedicated cermet grade

The uncoated cermet grade NS9530 is engineered for finishing steel components, delivering a sharp cutting edge that lowers cutting forces and improves surface integrity. Lower forces translate into reduced vibration and less tool-induced distortion, which in turn reduces the need for rework and inspection. For production environments where surface quality matters, the combination of a cermet cutting material and a finely honed geometry produces repeatable results in continuous cutting conditions and at small depths of cut. This makes the insert particularly suitable for precision components where a high-quality finish shortens downstream processing.

Predictable clamping and interchangeability with ISO holders

Designed to the ISO standard, the insert’s geometry and tolerances make compatibility with matching holders straightforward; fit is determined by form, clearance angle, tolerance class, fastening method, size and thickness. Key dimensional data such as the 15 mm inscribed size, 4.76 mm plate thickness and 0.4 mm corner radius support consistent seating and repeatable positioning in turn-holders and boring bars. The insert features a cylindrical mounting hole and a rhombic shape that enable secure fastening and precise indexation. The result is predictable tool behaviour across tool changes and reduced set-up time when migrating between machines or rebuilding tool assemblies.

Operational benefits, recommended applications and system context

The DNMG150404 NS9530 is double-sided and equipped with a chipbreaker suited for finishing, which helps produce short, controllable chips in stable cutting conditions. Typical use cases include external and internal turning where a fine surface finish and low cutting forces are required. The system approach comprises the ISO insert, a compatible outer holder or boring bar, a shim/clamp set and replacement screws; selecting the correct chipbreaker and grade for the workpiece, machining strategy and machine stability ensures best results. Where cutting conditions are continuous and depths of cut are modest, this finishing insert improves cycle reliability and contributes to predictable productivity.

Material suitability and practical notes for selection

This insert’s cutting material and geometry make it particularly effective on steels and allied materials that respond well to sharp-edged finishing grades. The uncoated cermet substrate is optimised for low built-up edge and high surface quality rather than heavy interrupted cuts; therefore, stability of the machining set-up and appropriate feeds should be prioritised. When machining less stable parts or performing heavy stock removal, consider a tougher grade or a tool with a positive chip control adapted to intermittent cutting. For system assembly and replacement parts, ensure the holder matches the insert’s rhombic form, 0° clearance angle, and thickness to maintain clamping integrity.
