DPMT 11T304 NS9530 – Tungaloy indexable insert for turning, rhombic 55°

The DPMT 11T304 NS9530 is an ISO‑standard rhombic indexable insert designed for precision external and internal turning, optimised for finishing steel components.

• Uncoated cermet grade NS9530 for finishing
• Sharp cutting edge for low cutting forces
• Rhombic 55° geometry with 0.4 mm corner radius
• Cylindrical hole with countersink for secure clamping

Superior finish with low cutting forces

The insert from the DPMT series offers an uncoated cermet composition in grade NS9530, developed for finishing operations on steel where a high surface finish is required. The combination of a sharp cutting edge and a single-sided chipbreaker reduces cutting forces and minimises vibration, which helps to achieve consistent part quality during continuous cuts and small depths of cut. The compact rhombic geometry and 0.4 mm corner radius contribute to controlled tool engagement and predictable wear, making this an economical option for precision turning tasks.

Easy integration and reliable compatibility

Compatibility with toolholders is determined by form, relief angle, tolerance class, fastening, size and thickness, so the ISO code 11T304 ensures straightforward selection for standard holders matched to the 55° geometry. The insert features a cylindrical hole with a one‑sided countersink (40°–60°) and a plate thickness of 3.97 mm, enabling secure clamping and repeatable seating. When choosing a chipbreaker and grade, select options that match the workpiece material and machining style; the combination of chip control and sharp geometry supports finishing on steels with reduced need for secondary operations.

Process reliability and practical benefits in production

A focus on stable cutting behaviour and predictable edge life makes this indexable insert suitable for batch production where repeatability matters. The ISO‑standard format simplifies tool inventory and reduces set‑up time, while the DPMT form factor provides flexibility for external and internal turning tasks. Using a finishing cermet grade reduces built‑up edge and often improves post‑process surface integrity, which can lower downstream rework and inspection effort. The Tungaloy manufacturing pedigree supports consistent performance, especially where tight tolerances and surface quality are priorities.
