DCMT 11T304 NS9530 — ISO turning insert (uncoated cermet) by Tungaloy

The DCMT11T304 NS9530 is an ISO‑standard rhombic insert engineered for finishing operations in turning, offering a sharp edge and low cutting forces for superior surface quality.

• ISO‑standard rhombic geometry
• Uncoated cermet for fine finishing
• 0.4 mm nose radius for precision
• Single‑sided chipbreaker, continuous cuts

Achieve finer surfaces with low cutting forces

The insert is an uncoated cermet grade NS9530, designed specifically as a finishing grade for steel where a high surface finish is essential. Cermet combines ceramic hardness with metallic toughness, enabling a sharp cutting edge that lowers friction and reduces the energy needed for cutting; this results in low cutting forces and improved component integrity. For operations with continuous cuts and small depths of cut, this geometry supports consistent surface quality and reduces the need for rework, improving overall process reliability.

Fast integration thanks to ISO conformity and robust geometry

Being ISO‑designated with a rhombic form, the insert ensures straightforward compatibility with standard toolholders when form, relief angle, tolerance class, fixation, size and thickness match. The 55° included angle and 7° relief angle provide a balanced contact zone between insert and workpiece, while the 3.97 mm thickness contributes to dependable clamping stability. The presence of a cylindrical hole with single‑side countersink (40°–60°) secures the insert in the pocket and simplifies repeatable indexing during production changeovers.

Predictable chip control and dimensional precision

A single‑sided chipbreaker combined with a 0.4 mm nose radius translates into better chip formation and stable cutting when running finishing passes. The chipbreaker geometry helps guide swarf away from the cutting zone, reducing the risk of surface damage and improving process safety. The modest nose radius balances surface finish and profile accuracy: small radii yield finer finishes with minimal radial engagement, ideal for precision turning and fine-tolerance features. For operators less familiar with insert selection, the function of the chipbreaker and radius can be summarised as measures that optimise chip evacuation and surface consistency during low-depth finishing cuts.

FAQ

What materials is this insert intended for?
The DCMT11T304 NS9530 uncoated cermet is intended primarily for finishing operations on steel, providing a sharp edge and low cutting forces tailored to continuous cuts and small depths of cut.

Which toolholders fit this insert?
Compatibility is achieved with standard ISO holders that accept the DCMT 11 size and match the insert’s form, relief angle and thickness; the hole and countersink ensure secure clamping.

What is the nose radius and how does it affect the finish?
The nose radius is 0.4 mm; this small radius supports a high surface finish while maintaining dimensional control on fine turning passes.

Is the insert single‑sided or double‑sided?
This insert features a single‑sided chipbreaker, enabling focused chip control and predictable performance for finishing cuts.

Does the insert include a clamping hole and countersink?
Yes — the insert has a cylindrical hole with a single‑side countersink designed between 40° and 60°, facilitating secure and repeatable clamping.
