DNGG 150402 NS9530 Turning Insert – Rhombic R0.2, Uncoated Cermet (Tungaloy)

The DNGG150402-01 NS9530 is an ISO‑standard rhombic turning insert designed for finishing operations on steel, offering a sharp cutting edge and optimised chip control for continuous cuts.

• ISO‑standard rhombic geometry
• Uncoated cermet grade NS9530
• 0.2 mm corner radius for fine finishes
• 55° approach angle, 0° relief angle

Superior finish with low cutting forces

The combination of the NS9530 uncoated cermet and a sharp cutting geometry delivers a consistently high surface finish while reducing cutting forces. As a finishing grade, the substrate and edge preparation are tuned for continuous cuts and small depths of cut, which means less load on the machine spindle and more reliable dimensional results. This makes the insert particularly suitable where fine surface quality and repeatable part accuracy are priorities.

Reliable integration into ISO tooling systems

Compatibility is ensured by adherence to ISO standards: the insert’s rhombic geometry, thickness (4.76 mm), size (15 mm), relief angle (0°) and mounting hole determine the correct holder choice. Select a matching external holder or boring bar that accommodates the plate form, tolerance class and clamping method to achieve secure fixation and repeatable cutting position. The 55° approach angle supports controlled entry conditions and predictable chip flow when paired with an appropriate chipbreaker and stable clamping setup.

Practical shopfloor advantages and handling

A 0.2 mm corner radius balances edge strength with surface integrity, enabling fine finishing without compromising edge life under normal finishing parameters. The insert is supplied as part of a system concept: ISO insert, matching holder or boring bar, shim/clamping set and replacement screws. Choose the chipbreaker and grade according to workpiece stability and the machining strategy; for continuous finishing of steel, the uncoated cermet NS9530 offers low cutting resistance and excellent surface outcomes.

FAQ

What materials is this insert designed for?
The DNGG150402-01 NS9530 Tungaloy turning insert is engineered primarily for finishing steel, where the uncoated cermet grade achieves low cutting forces and high surface quality.

How does the NS9530 grade affect machining?
NS9530 provides a sharp cutting edge and is optimised for continuous cuts; the DNGG150402-01 NS9530 Tungaloy insert therefore delivers fine surface finishes with reduced cutting resistance.

Which holders are compatible with this insert?
Compatibility depends on holder form, relief angle, tolerance class, clamping method, size and thickness; pair the DNGG150402-01 NS9530 Tungaloy insert with an ISO‑compatible external holder or boring bar matching these parameters.

What is the significance of the 0.2 mm corner radius?
A 0.2 mm corner radius on this Tungaloy insert balances edge strength and surface integrity, making it suitable for finishing passes where dimensional accuracy and surface quality are important.

Is the insert suitable for internal machining?
Yes, the ISO‑standard design of the DNGG150402-01 NS9530 Tungaloy turning insert allows use in both external and internal turning applications when matched with the correct boring bar and clamping system.
