DNMG150404 NS9530 Tungaloy turning insert — ISO rhombic finishing insert, 0.4 mm radius

The DNMG150404 NS9530 Tungaloy turning insert is an ISO‑standard, rhombic insert designed for finishing operations in turning, optimised for steel machining with a carbide substrate and uncoated cermet grade.

• ISO‑standard rhombic turning insert
• Uncoated cermet grade NS9530 for fine finishing
• 0.4 mm corner radius for superior surface quality
• Cylindrical hole, compatible with standard holders

Achieve consistently high surface quality with a finishing grade designed for steel

The insert combines a carbide substrate with an uncoated cermet cutting material, offering a sharp cutting edge and low cutting forces that help maintain dimensional accuracy during finishing passes. The geometry and material selection promote continuous chip flow and minimise built‑up edge, which translates into improved surface finishes and fewer reworks. As an ISO‑conforming rhombic insert, it fits a broad range of standard holders when the form, clearance angle and tolerance class are matched, simplifying tool changeovers in production environments.

Stable performance through refined geometry and double‑sided usability

With a 0.4 mm corner radius and a 55° included angle, this insert is tailored for fine turning where surface integrity matters. The double‑sided chipbreaker design extends tool life by balancing cutting forces and controlling chip formation, especially in continuous cuts and small depths of cut. The cylindrical hole ensures secure clamping in compatible toolholders and facilitates repeatable positioning. These technical characteristics reduce vibration sensitivity and support consistent cycle times on medium‑ to high‑rigidity setups.

Practical compatibility and application guidance for workshop use

The insert is supplied in the ISO designation DNMG150404 and is intended primarily for turning stainless and carbon steels in finishing applications; select the chipbreaker and grade according to workpiece material and machining stability. The NS9530 grade is particularly suited to continuous turning with small feeds, where a sharp edge and good surface finish are required. When integrating the insert into an existing tool system, verify holder compatibility by checking form, free clearance angle, tolerance class, fixing method, size and thickness to ensure secure, accurate clamping.

FAQ

What materials is this insert suited for?
The DNMG150404 NS9530 is a finishing grade designed predominantly for steel machining; the uncoated cermet provides a sharp edge and low cutting forces suitable for continuous turning and small depths of cut.

Is the insert reversible or single‑use?
The insert is double‑sided with a reversible geometry, allowing both cutting edges to be used before replacement, which improves cost efficiency and tool utilisation.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, free clearance angle, tolerance class, fixing method, size and thickness; the DNMG150404 designation follows ISO standards and fits holders built to the same ISO specification when these parameters match.

Does the grade have a coating?
No, the NS9530 grade supplied here is an uncoated cermet, chosen for its sharp edge and superior surface finish in finishing operations.

What edge preparation does the 0.4 mm radius provide?
A 0.4 mm corner radius balances edge strength and surface finish, offering reduced chipping risk compared with sharper radii while maintaining the ability to achieve fine surface quality in finishing passes.
