CPMT080204 NS9530 — ISO rhombic turning insert for finishing, Tungaloy (11° clearance, 0.4 mm corner radius)

The CPMT080204 NS9530 is a rhombic ISO turning insert designed for finishing operations on steel, offering a sharp cutting edge and consistent surface quality in continuous cuts.

• Uncoated cermet for finishing
• Sharp edge for low cutting forces
• Rhombic ISO form CPMT
• Cylindrical hole with countersink

Precision finishing for continuous turning

The rhombic ISO insert delivers a reliably smooth finish for long runs and continuous cuts. With the NS9530 cermet grade and its deliberately sharp cutting edge, the insert reduces cutting resistance and helps achieve superior surface finish on steel components. The modest corner radius (0.4 mm) and thin section make the geometry particularly suited to small depths of cut and fine-turning tasks, where dimensional control and repeatable part quality are decisive. Compatibility with standard ISO holders is determined by the insert form, clearance angle and tolerance class, allowing straightforward integration into existing tool systems.

Improved productivity through reduced forces and stable edge life

Selecting an uncoated cermet insert for finishing brings tangible productivity gains: lower cutting forces reduce vibration and tool deflection, which shortens machining times by reducing the need for reworking and part inspection. The single-sided chipbreaker and the precise 11° clearance ensure predictable chip flow in continuous operations, stabilising the cutting process and extending effective edge life. For batch production where surface integrity and cycle consistency matter, this insert supports a cost-effective balance between throughput and finish quality.

Practical compatibility and mounting details for reliable set-up

The insert is an ISO-format CPMT plate with a cylindrical hole and a single-side countersink (40°–60°), thickness 2.38 mm, included angle 80°, and rhombic shape — features that define how it seats in the clamping system and how torque loads are transferred. The compatibility with holders depends on the insert form, free angle, tolerance class, fastening and dimensional fit; matching these parameters avoids underclamping and ensures repeatable positioning. For applications requiring continuous fine cuts on steel, this combination of geometry and the NS9530 grade provides a predictable, high-quality finish with minimal secondary processing.

FAQ

What materials is this insert suited for?
The CPMT080204 NS9530 Tungaloy turning insert (SKU 6998448-Tungaloy) is intended primarily for finishing steel workpieces, optimised for continuous cuts and small depths of cut.

How does the NS9530 grade influence surface finish?
The uncoated NS9530 cermet offers a very sharp cutting edge and low cutting forces, helping to produce a finer surface finish and reduced need for subsequent polishing when the insert is used in finishing operations.

Which holders are compatible with this ISO insert?
Compatibility depends on insert form, clearance angle, tolerance class, fastening and dimensional fit; the CPMT geometry and the cylindrical hole with countersink are designed for standard ISO CPMT holders and clamping systems.

What cutting conditions are recommended for best results?
Best results are typically achieved with light depths of cut and continuous feed suitable for finishing; the combination of NS9530 and the small corner radius supports stable cutting at modest feed rates for high-quality finishes.
