DCMT DCMT11T308 NS9530 indexable turning insert for turning — Tungaloy

A DCMT11T308 NS9530 indexable insert engineered for finishing turning operations on steel, offering a sharp uncoated cermet grade for low cutting forces and high surface quality

• Finishing cermet grade NS9530 with sharp edge
• Low cutting forces for continuous cuts
• ISO‑compliant DCMT11T308 geometry
• Cylindrical hole, one‑side countersink 40°–60°

Consistent finishing and superior surface quality

The geometry and material selection focus on delivering reliable finishing results on steel components. The combination of a sharp uncoated cermet grade and the rhombic insert form produces low cutting forces and reduced vibration, which directly translates into a finer surface finish and fewer rework cycles. The insert’s design supports continuous cuts and small depths of cut, making it especially suitable where surface integrity and dimensional consistency are priorities.

Predictable process control and efficiency

Designed to reduce machining variability, this insert supports stable chip formation and repeatable results under consistent conditions. The one‑sided chipbreaker is tuned for finishing and helps maintain a uniform chip flow, while the low force requirement lowers tool‑holder stress. Together, these characteristics improve cycle time reliability and can contribute to overall process efficiency and cost control in production environments.

Clear compatibility with standard holders and clamping systems

Compatibility with toolholders is determined by form, relief angle, tolerance class, clamping, size and thickness. The ISO DCMT geometry ensures wide availability of matching external holders and boring bars; ensure the holder matches the 7° relief and the insert thickness. The cylindrical hole with a single‑side countersink (40°–60°) requires the corresponding screw and seat for secure clamping and precise repeatability in multi‑station setups.

What the material and grade mean in practice

The NS9530 grade is an uncoated cermet, optimised for finishing steel with a focus on a sharp cutting edge and low built‑up edge tendency. Cermet combines ceramic hardness with metal toughness to maintain edge integrity at finishing feeds and speeds; in practice this means improved surface finish without the need for aggressive machining parameters. The absence of a coating reduces sensitivity to thermal cycling during fine finishing passes.

Recommended applications and processing approach

Intended primarily for external and internal finishing, the insert is best applied where continuous cuts and modest depths of cut are used. Select the chipbreaker and grade according to the workpiece material and the machine‑tool stability: the NS9530 grade excels in steady conditions on steel. For interrupted cuts or unstable setups, consider alternative chip management strategies or different grades to preserve edge life.

Availability, handling and technical support

Supplied as an ISO‑norm insert ready for standard indexable systems, the DCMT11T308 format facilitates fast replacement and minimal setup time. For queries about holder matching, clamping screws or application‑specific recommendations, Metav Werkzeuge provides technical support and can advise on optimised insert selection to extend tool life and enhance process security.

FAQ

What materials is this insert suited for?
The DCMT11T308 NS9530 Tungaloy insert is optimised for finishing operations on steel, delivering low cutting forces and excellent surface finish on continuous cuts.

Is the insert coated?
No — the NS9530 is an uncoated cermet grade; the lack of coating supports a very sharp edge suited to finishing and helps avoid coating‑related adhesion at low depths of cut.

Which holders fit this insert?
Compatibility requires a holder matching the DCMT11T308 geometry, the 7° relief and the insert thickness; ensure the toolholder clamp suits the cylindrical hole and countersink specification.

What cutting style and conditions are recommended?
Best results are achieved with continuous cutting and small depths of cut; the insert is a finishing grade and performs best under steady machining with appropriate chip evacuation.

How does the chipbreaker affect machining?
The one‑sided chipbreaker is designed for finishing, promoting stable chip formation and consistent surface quality when matched with appropriate feeds and speeds.
