DCMT 11T304 NS9530 Tungaloy turning insert — DCMT, ISO 55° rhombic, 0.4 mm radius

The DCMT11T304 NS9530 Tungaloy turning insert is an ISO‑standard rhombic indexable plate designed for finishing operations in turning, offering a sharp, low‑force cutting geometry for steels.

• ISO rhombic DCMT shape, 55° cutting angle
• NS9530 uncoated cermet for fine finishing
• 0.4 mm corner radius for high surface quality
• One-sided chipbreaker with locating hole

Precision finishing tailored for steel turning

The insert is a DCMT‑format, ISO‑standard plate optimised for finishing on steel. The NS9530 grade is an uncoated cermet formulated to deliver a high surface finish with low cutting forces, which reduces vibration and improves dimensional consistency. As a result, process stability increases during continuous cuts and when taking small depths of cut, yielding fewer reworks and a more predictable part quality.

Geometry and mounting that ensure compatibility and repeatability

With a 55° rhombic cutting geometry and a 0.4 mm corner radius, the geometry supports accurate profile reproduction and edge stability. The insert thickness of 3.97 mm and ISO size 11 make the plate compatible with standard external holders, while the mounting is secured through a cylindrical locating hole with a one‑side countersink (40°–60°). Compatibility with a given holder depends on form, clearance angle, tolerance class, fastening, size and thickness, which ensures reliable repeatable clamping in production environments.

Chip control and cutting behaviour explained for shopfloor decisions

The single‑sided chipbreaker incorporated on the insert is tuned for finishing applications and continuous cutting; it assists in producing short, controllable chips, which simplifies chip evacuation and reduces interference with the workpiece. For operations requiring a smooth surface and reduced cutting forces, the uncoated cermet NS9530 provides a sharp cutting edge and stable wear behaviour, making it a pragmatic choice for consistent finishing cycles.

Operational benefits and economical considerations

Using a finishing grade such as this insert improves surface quality and can extend tool life under the right cutting conditions, which saves time on downstream processes. The insert’s balanced combination of geometry and grade supports predictable performance in repetitive turning tasks, aiding machining planners who prioritise throughput and reproducibility. Selection of the appropriate chipbreaker and holder pairing remains the primary determinant of overall process efficiency.
