CCMT 09T304 NS9530 – ISO turning insert, uncoated cermet finishing (Tungaloy)

CCMT 09T304 NS9530 is an ISO rhombic turning insert designed for finishing steel, providing a precise edge geometry and low cutting forces for continuous, fine-turning operations.

• ISO rhombic insert CCMT 80° geometry
• Uncoated cermet NS9530 for finishing
• Sharp edge for low cutting forces
• Suitable for continuous turning and fine cuts

High-precision finishing for superior surface quality

The insert delivers a measurable improvement in surface finish thanks to the uncoated cermet grade NS9530, which combines a sharp cutting geometry with stable wear behaviour. With a nose radius 0.4 mm and an 80° rhombic form, the geometry is optimised for small depths of cut and continuous cutting, producing consistent finishes while keeping cutting forces low. The result is reduced need for secondary operations and a predictable part quality in serial production.

Increased process stability through controlled chip formation

Designed as a finishing grade, the substrate and edge preparation promote stable chip formation and reduced micro-chipping. The sharp cutting edge lowers the force transmitted to the workpiece, which decreases vibration and supports repeatable results across batches. Compatibility with the machining system is governed by holder form, clearance, tolerance class, fastening method, size and thickness, ensuring that the insert integrates smoothly into existing tooling setups and contributes to higher throughput with fewer interruptions.

Simple mechanical integration and predictable clamping

The ISO system format simplifies replacement and setup: the insert features a cylindrical hole with a single-sided countersink (40°–60°) for secure fastening and positional repeatability. At a thickness of 3.97 mm and a clearance angle of 7°, the geometry supports stable clamping and precise tool-path control. The single-sided chipbreaker is tuned for finishing cuts, and the standardised form factor allows ready pairing with appropriate external holders or boring bars to achieve the intended cutting conditions with minimal adjustment. The CCMT 09T304 NS9530 insert thus supports efficient changeover and consistent process behaviour.
