DCMT11T308 NS9530 Tungaloy turning insert — ISO DCMT, 55° rhombic, 0.8 mm radius

The DCMT11T308 NS9530 is an ISO‑standard rhombic turning insert engineered for fine finishing in Stahl turning, optimised for continuous cuts and small depths of cut.

• ISO‑standard DCMT shape, 55° geometry
• NS9530 uncoated cermet for fine finishing
• Sharp cutting edge for low cutting forces
• 0.8 mm nose radius for superior surface finish

Consistent surface quality and cutting performance

The NS9530 grade is an uncoated cermet developed for finishing applications in Stahl, offering a sharp cutting edge that reduces cutting forces and improves surface integrity on continuous cuts. The combination of low friction and edge stability means the insert delivers repeatable part finish and dimensional consistency, especially at small depths of cut. The modest nose radius and precise edge preparation lower the risk of built‑up edge and support a stable machining window for finishing passes.

Reliable geometry and holder compatibility for predictable results

The insert follows an ISO‑standard DCMT form with a 55° rhombic geometry and a 7° relief angle, ensuring compatibility with a wide range of turning holders designed for DCMT‑type inserts. The part includes a cylindrical hole with single‑side countersink (40°–60°) and a plate thickness of 3.97 mm, which together determine clamping behaviour and torque requirements. Matching holder form, tolerance class, fastening and size guarantees correct seating and repeatable cutting conditions, reducing setup time and scrap.

Practical machining guidelines and shop benefits

For best results, select a chipbreaker and feed that suit finishing cuts and the continuous‑cut characteristic of this grade; the single‑sided chipbreaker supports controlled chip flow on smaller depths of cut. The insert is supplied in the DCMT11T308 ISO designation, with a 0.8 mm corner radius that favours improved surface finish while maintaining edge strength. As an uncoated cermet, it performs particularly well in finishing applications where thermal stability and cutting edge sharpness take priority. Choosing this insert contributes to shorter cycle times and fewer reworks when paired with appropriate machining parameters and a stable setup.

FAQ

What materials is this insert suited for?
The DCMT11T308 NS9530 insert is intended primarily for finishing in Stahl; the NS9530 uncoated cermet grade is optimised for low cutting forces and high surface quality on continuous cuts.

How does the 0.8 mm radius affect the surface finish?
A 0.8 mm corner radius balances edge strength and finish quality—this radius helps the NS9530 grade produce superior surface integrity while maintaining stable cutting behaviour during finishing passes.

Which holders are compatible with this DCMT insert?
Compatibility depends on holder form, relief angle, tolerance class, fastening and plate thickness; the DCMT11T308 follows ISO standards and fits holders designed for DCMT inserts with a 55° rhombic geometry and 7° relief angle.

Is the insert coated?
The NS9530 grade is an uncoated cermet, specified for finishing applications where a sharp cutting edge and low cutting forces are required.
