DCMT11T304 NS9530 DCMT Turning Insert (Tungaloy)

A DCMT11T304 NS9530 turning insert designed for ISO‑standard external and internal turning, optimised for fine finishing on steel

• ISO rhombic insert DCMT 11T304
• NS9530 cermet finishing grade
• 0.4 mm nose radius for fine surface
• 7° clearance angle for low cutting forces

Consistent fine finishing and measurable productivity gains

The NS9530 grade is an uncoated cermet developed for finishing operations on steel where a sharp cutting edge and low cutting forces are essential. This composition delivers a combination of excellent surface quality and reduced built‑up edge tendency during continuous cuts. As a result, cycle times can be optimised without compromising part finish, which supports more predictable process windows and higher overall throughput in serial turning applications.

Secure seating and ISO compatibility for reliable operation

Designed to the ISO plate form DCMT and supplied with a cylindrical hole and single‑side countersink (40°–60°), the insert ensures secure clamping in compatible toolholders. The rhombic shape and the specified 7° clearance angle reduce radial cutting pressures and improve chip flow when paired with appropriate chipbreaker geometry. Compatibility with ISO holders depends on form, clearance angle, tolerance class, fixing method, size and thickness, so selection of the matching holder and clamping set is recommended to maintain repeatable assembly and machining accuracy.

Practical selection advice for finishing on steel

With a 0.4 mm nose radius and a thin 3.97 mm plate thickness, the insert is optimised for small depths of cut and continuous finishing passes. The one‑sided chipbreaker suits stable cutting conditions and helps control chip shape for predictable evacuation. When choosing this grade for a turning task, consider machine rigidity, cutting speed and feed: a stable set‑up with appropriate feeds will exploit the NS9530 finishing characteristics to achieve superior surface integrity and dimensional consistency. The designation DCMT11T304 indicates the geometry and size for straightforward tooling specification.

FAQ

What materials is this insert intended for?
The DCMT11T304 NS9530 insert is specified as a finishing grade for steel and is optimised to provide high surface quality under continuous cutting conditions.

Can the insert be used for internal turning as well as external turning?
Yes, the ISO rhombic geometry and the specified chipbreaker make the insert suitable for both external and internal turning operations when the correct holder and setup are used.

How does the 0.4 mm nose radius affect the finished part?
A 0.4 mm nose radius supports fine surface finish and dimensional control on small depths of cut; it is particularly effective in finishing passes where surface integrity is critical.

What does the hole style mean for clamping?
The insert's cylindrical hole with a single‑side countersink (40°–60°) is designed for secure mechanical clamping in compatible ISO toolholders, ensuring repeatable seating and stable cutting performance.

Which specifications should be matched when selecting a holder?
Holder compatibility depends on form, clearance angle (7°), tolerance class, fixing method, size and thickness (3.97 mm); matching these parameters ensures reliable clamping and repeatable results.
