CPMT090308 NS9530 Tungaloy — CPMT 090308 ISO turning insert for finishing, 0.8 mm corner radius

CPMT090308 NS9530 Tungaloy is a rhombic indexable insert designed for precision external and internal turning in finishing applications on steel

• Cermet finishing grade NS9530
• Sharp cutting edge for high surface finish
• 0.8 mm corner radius for fine profiles
• 11° clearance angle; ISO rhombic form

Consistent finishing quality with a low-force cermet grade

The uncoated cermet grade NS9530 is tailored for finishing operations on steel, offering a sharp cutting edge that reduces cutting forces and improves surface integrity. For continuous cuts and small depths of cut, this composition yields high surface finish and consistent part geometries, reducing the need for secondary smoothing processes. The combination of edge stability and a fine corner radius supports tight tolerances and repeatable results on batches where part appearance and dimensional accuracy are critical.

Precision geometry that simplifies holder selection and set-up

Built to ISO conventions, the rhombic plate form with a nominal size 09 integrates a defined clearance geometry — 11° free angle and an included angle of 80° — that ensures predictable engagement with matching toolholders. The 0.8 mm corner radius and 3.18 mm thickness deliver a robust seating and predictable strength at the cutting edge. The insert features a cylindrical hole with a one‑side countersink (40°–60°) to secure correct clamp seating and repeatable positioning; compatibility with a given holder is governed by form, clearance, tolerance class, fastening, size and thickness.

Shop-floor efficiency and measurable process benefits

Adopting this finishing insert can shorten cycle times by reducing downstream rework: the low cutting forces translate into diminished machine load and more stable cutting conditions, while the edge quality lessens the frequency of quality rejections. In practice, the grade's behaviour in finishing passes promotes consistent surface results, which supports throughput improvements and cost control across high-volume or precision-focused turning operations. These performance gains position the insert as a pragmatic component in process optimisation.

Practical guidance for integration and tool-system planning

When specifying the insert, select a one‑sided chipbreaker that matches the workpiece material and the machining stability available; the single-sided chipbreaker on this plate supports chip control in finishing cuts. The system concept comprises the ISO insert, the matching external holder or boring bar, a locating pad/clamping set and the appropriate clamp screws. For reliable operation, ensure the holder accepts a plate with a 3.18 mm thickness and the described hole/countersink arrangement. For questions on holder matching or chipbreaker choice, technical consultation is recommended to align insert, holder and process parameters.
