DCGT 11T308 NS9530 ISO rhombic turning insert for turning by Tungaloy

The DCGT11T308 NS9530 is an ISO‑standard rhombic turning insert for finishing steels, offering a sharp cutting edge, low cutting forces and suitability for continuous cuts.

• ISO rhombic insert, 55° geometry
• Uncoated cermet grade NS9530
• Sharp edge for high surface finish
• Compatible with standard ISO holders

High‑quality finishing with low cutting forces

The uncoated cermet grade NS9530 is engineered as a finishing grade for steel, providing a sharp cutting edge that reduces cutting forces and improves surface quality. In practice, the result is a consistently fine finish on turned parts, especially when machining with small depths of cut and continuous feed. For operations prioritising surface integrity over heavy material removal, this grade offers reproducible outcomes and helps to reduce rework.

ISO compatibility and secure clamping for reliable production

The insert follows ISO geometries so compatibility with standard holders is determined by form, relief angle, tolerance class, fastening method, size and thickness. The plate has a rhombic profile with a 55° included angle and a 7° relief angle, and it is supplied with a cylindrical hole and a one‑sided countersink (40°–60°) to match many common clamping systems. Clear knowledge of these parameters supports safe, repeatable mounting and predictable cutting behaviour.

Practical guidance for efficient turning operations

Designed primarily for turning in continuous cuts with small depths of cut, the insert excels in external and internal finishing passes. Selection of an appropriate chipbreaker and the matching grade according to material, machining strategy and component stability is essential; the insert’s single‑side chipbreaker suits stable setups and steady feed rates. Where vibration is minimised and rigidity is ensured, the combination of geometry and grade maximises surface quality while keeping cutting forces low.

Compact geometry and handling advantages on the shop floor

The insert’s compact dimensions provide geometric control: a 0.8 mm corner radius and a thickness of 3.97 mm contribute to predictable edge strength and profile control during finishing passes. The substrate material is carbide, offering the edge stability required for precision turning. Where tight tolerances and consistent finishes are required, the insert’s specifications support repeatable results and efficient tool management.

FAQ

What machining tasks is this insert intended for?
The DCGT11T308 NS9530 indexable turning insert from Tungaloy is intended for finishing operations in turning, particularly continuous cuts and small depths of cut on steel.

Which materials can be machined with this grade?
The NS9530 cermet grade is optimised for steel; the DCGT11T308 insert delivers a sharp cutting edge and low cutting forces suited to fine finishing of steel parts.

How is the insert secured in the holder?
The insert is supplied with a cylindrical hole and a one‑sided countersink (40°–60°); compatibility with a holder depends on form, relief angle, tolerance class, fastening and size.

What benefits does the 0.8 mm corner radius provide?
A 0.8 mm corner radius on the DCGT11T308 helps balance edge strength and surface finish, allowing stable profile control during finishing passes.

Is the insert coated?
The DCGT11T308 is an uncoated cermet insert (NS9530), selected for its sharp edge and high surface finish capabilities.
