DCGT 11T302 NS9530 Tungaloy — Turning insert (finish), ISO 11T302

DCGT11T302 NS9530 is an ISO-conforming indexable turning insert for finishing operations on steel, offering a sharp cutting edge and optimised chip control.

• Uncoated cermet for fine finishing
• Sharp cutting edge for low cutting forces
• Rhombic DCGT shape with 7° clearance
• Single-sided chipbreaker, 0.2 mm radius

Consistent finishing thanks to a dedicated cermet grade

The NS9530 grade is an uncoated cermet developed for finish turning of steel, delivering a very sharp cutting edge and low cutting forces that promote superior surface quality. Cermet (a ceramic–metal composite) combines ceramic hardness with metallic toughness; this means the insert holds a keen edge longer under continuous, light-depth cuts and produces less built-up edge than many traditional grades. The result is reliable finish performance and reduced rework in parts where surface integrity matters.

ISO compatibility and geometric precision for fast tool changes

The insert follows ISO specification 11T302 and the DCGT rhombic form, so compatibility with holders is determined by form, clearance, tolerance class, attachment, size and thickness. The 7° clearance angle and standard dimensions support rapid tool change and secure clamping, reducing machine downtime. With a plate thickness of 3.97 mm and ISO sizing, the component fits established tool systems, enabling predictable repeatability across serial production and tooling setups.

Geometry tailored to surface quality and chip control

A 0.2 mm nose radius combined with a single-sided chipbreaker and a rhombic shape yields fine surface finish while maintaining consistent chip formation. The insert features a cylindrical hole with a single-sided countersink (40°–60°) which ensures secure fastening and correct seating in compatible holders. The modest radius aids in producing dimensionally accurate profiles during finishing passes while the chipbreaker supports effective evacuation when cutting continuous chips.

Application focus and machining guidance

Designed primarily for turning, this insert performs best in finish operations on steels with small depths of cut and continuous chip flow. Select an appropriate chipbreaker and holder stability according to the workpiece and machining conditions to exploit the grade’s strengths. The insert’s geometry (including the 55° approach angle) supports delicate finishing passes where surface quality and dimensional precision are the priority. For intermittent cuts or heavy roughing, consider different geometries or tougher grades.

FAQ

What steels is the DCGT11T302 NS9530 best suited for?
The DCGT11T302 NS9530 insert is optimised for finish turning of a broad range of steels, delivering a sharp edge and low cutting forces that support high surface quality on continuous cuts.

How does the uncoated cermet grade NS9530 affect tool life?
The uncoated cermet composition of the NS9530 grade maintains a very sharp cutting edge for finishing passes, which can extend effective productive life where cutting temperatures and continuous cuts prevail.

Which geometry features support surface finish with this insert?
The combination of a 0.2 mm nose radius, single-sided chipbreaker and rhombic DCGT form helps produce fine surface finishes and controlled chips during finishing operations.

Is the insert compatible with standard ISO holders?
Yes; the insert follows ISO designation 11T302 and its compatibility depends on form, clearance angle, tolerance class, attachment and thickness to match standard holders.

Can the DCGT11T302 NS9530 be used for interrupted cuts?
The grade and geometry are optimised for continuous finish turning; for severe interrupted cuts or heavy roughing, a tougher grade or different geometry is advised.
