CPGT090304 NS9530 — ISO rhombic turning insert for turning, 11° clearance (Tungaloy)

The CPGT090304 NS9530 is an ISO‑standard rhombic insert designed for finishing turning of steel, combining an uncoated cermet grade with a sharp cutting edge for low cutting forces and superior surface quality.

• Uncoated cermet grade NS9530
• Sharp cutting edge for finishing
• 11° clearance angle for stable cuts
• Rhombic 09, 3.18 mm thickness

Exceptional surface finish for finishing operations

The uncoated cermet grade NS9530 is optimised for finishing operations on steel, offering a sharp cutting edge that reduces built-up edge and enables lower cutting forces. This results in high surface finish with minimal tool-induced vibration during continuous cuts and small depths of cut. The material combination provides thermal stability at finishing speeds and helps maintain dimensional accuracy across long batches, making the insert suitable for components where surface integrity is critical.

ISO compatibility and secure clamping for predictable performance

Designed to the ISO geometry, the insert’s rhombic form and tolerance class ensure repeatable seating in standard holders; compatibility depends on form, clearance angle, tolerance, fixation, size and thickness. The insert features a cylindrical hole with a one‑sided countersink (40°–60°) to match indexed clamping systems and replacement screws. Correct selection of a matched holder and underlay yields secure clamping, consistent tool projection and predictable cutting forces, reducing setup variability and scrap rates in production turning lines.

Practical guidance to improve cycle-time and reduce rework

With a corner radius of 0.4 mm and a thickness of 3.18 mm, the insert supports low‑depth, high‑quality finishing cuts where chip control and surface integrity are priorities. The one‑sided chipbreaker supports effective chip formation for continuous cuts on steels, while the uncoated cermet substrate preserves the edge geometry for repeated passes. Selecting this finishing grade can shorten downstream operations, lower the need for secondary polishing and contribute to overall productivity gains on medium‑ to high‑volume turning processes.

FAQ

What materials is this insert suitable for?
The NS9530 uncoated cermet grade is intended primarily for finishing operations on steel; the insert is optimised for continuous cuts and small depths of cut where surface quality is essential.

Is the insert coated?
This indexable insert is an uncoated cermet grade (NS9530), chosen for its sharp edge and thermal stability in finishing applications.

Which insert geometry and size does it have?
The insert is a rhombic 09 form with a corner radius of 0.4 mm, a thickness of 3.18 mm and an included angle of 80°.

How is the insert clamped in the holder?
Clamping relies on ISO‑standard seating; the insert has a cylindrical hole with a one‑sided countersink (40°–60°) to suit standard clamping screws and underlays for secure indexing.

Can this insert be used for roughing operations?
This grade is a finishing sort with a sharp cutting edge and low cutting forces; for heavy roughing operations a more robust grade and a different chipbreaker are recommended.
