DNGG150408 NS9530 Tungaloy indexable turning insert for turning, rhombic 55°

DNGG150408 NS9530 is an ISO‑standard rhombic indexable insert designed for precision finishing in turning operations on steel.

• ISO rhombic insert DNGG150408
• NS9530 cermet for finishing steel
• 0.8 mm corner radius for fine finishes
• Double-sided chipbreaker with central hole

Precise finishing with a dedicated cermet grade

The NS9530 grade is an uncoated cermet developed for finishing applications on steel, offering a sharp cutting edge, reduced cutting forces and excellent surface finish. As a finishing grade, it is optimised for continuous cuts and small depths of cut, which translates into a predictable part quality and reduced rework. The substrate is cemented carbide, ensuring a stable edge and consistent performance in typical turning tasks.

Secure mounting and straightforward holder compatibility

The insert follows ISO geometries, so compatibility with external holders or boring bars depends on form, clearance angle, tolerance class, clamping method, size and thickness. The rhombic form combined with a cylindrical central hole and a double-sided chipbreaker gives a secure fit and repeatable seating, while the 0° clearance and 55° included angle support controlled chip flow and predictable contact conditions. These design choices simplify tool changeovers and help maintain process stability across shifts.

Productivity gains through consistent surface quality

By using a finishing‑specific grade and a 0.8 mm corner radius, shops gain faster sign‑off on finished components due to improved surface integrity and fewer manual finish operations. The insert is suitable for both external and internal turning; selecting the correct chipbreaker and grade according to workpiece material, machining type and machine stability will maximise tool life and minimise cycle times. Where process optimisation is required, pairing the insert with the appropriate holder and clamping parts in a matched system enhances repeatability and reduces downtime.

FAQ

What materials is this insert intended for?
The NS9530 grade in the DNGG150408 insert is intended primarily for finishing on steel and delivers a fine surface finish with low cutting forces.

Is the insert double sided and reversible?
Yes, the insert features a double-sided chipbreaker, allowing the cutting edge to be reused by reversing the insert to its second side.

How is the DNGG150408 mounted in the holder?
Mounting relies on the cylindrical central hole and the ISO rhombic form; correct selection of the matching holder and clamping set ensures repeatable seating and secure clamping.

Can the insert be used for internal turning (boring)?
The cutting geometry and compact size make the insert suitable for internal turning when paired with an appropriate boring bar and stable setup.

What advantages does the NS9530 cermet provide in production?
NS9530 offers a sharp edge and consistent cutting behaviour for finishing, reducing manual finishing steps and supporting predictable part quality in continuous cuts.
