CPMT080204 NS9530 — CPMT 080204 NS9530 turning insert for finishing, 0.4 mm radius, 11° relief (Tungaloy)

CPMT080204 NS9530 is an ISO rhombic indexable insert designed for finishing turning, offering a sharp uncoated cermet cutting edge and single-sided chip control.

• CPMT080204 ISO rhombic geometry
• Sharp-edge uncoated cermet grade NS9530
• 0.4 mm nose radius for fine surface finish
• Cylindrical hole with single-side countersink

High-quality finishing with a dedicated cermet grade

The NS9530 grade is an uncoated cermet developed for finishing operations in steel where a sharp cutting edge and low cutting forces are required. Compared with conventional carbide grades, cermet delivers superior surface integrity at small depths of cut and continuous feed conditions, reducing the need for secondary finishing. The fine 0.4 mm nose radius and the single-sided chipbreaker contribute to consistent surface roughness and dimensional accuracy. For planners and operators, this means fewer grinding passes and a higher first-pass yield on shafts, journals and turned faces.

Precise fit and repeatability with ISO-compliant geometry

The insert conforms to ISO dimensions for rhombic turning plates and is specified as size 08 with a thickness of 2.38 mm, an included angle of 80° and an 11° relief. Compatibility with a holder depends on form, relief angle, tolerance class, mounting method, size and thickness; using the correct ISO external holder or boring bar ensures secure clamping and repeatable positioning. The cylindrical hole with a single-side countersink (40°–60°) simplifies alignment and provides stable fixation under intermittent loads. For production environments that require dependable repeatability, the standardised geometry reduces setup time and improves process stability.

Efficiency and process benefits for turning steel

Engineered for turning of steel, this indexable plate supports continuous cutting and small depth-of-cut finishing strategies, enabling shorter cycle times without sacrificing finish quality. The sharp cermet edge reduces feed forces, which lowers spindle load and can permit slightly higher feeds while maintaining required surface tolerance — a clear rational advantage in high-mix or batch production. Selecting this finishing grade in the system stack-up (insert + holder + shim/clamp + screw) helps to maintain consistent tool life and predictable replacement intervals, supporting production planning and cost-per-part calculations.

System integration, selection and practical advice

The ISO insert is intended to be used within a complete system: a matched external holder or boring bar, a suitable backing/shim or clamp set and replacement screws. Choose the single-sided chipbreaker and NS9530 grade when prioritising surface finish and low cutting forces; when facing interrupted cuts or harder materials, opt for a different chipbreaker or a tougher grade. For application matching — for instance, selecting the correct holder geometry and tolerance class — the technical advisors at Metav Werkzeuge can provide tailored recommendations based on component drawing, machine rigidity and material batch. This combines technical support with practical selection, reducing trial-and-error at the machine.

FAQ

What materials is this insert best suited for?
The NS9530 cermet grade is optimised for finishing operations in steel; the CPMT080204 NS9530 insert gives low cutting forces and high surface quality on continuous turning of steel components.

Is the insert coated?
This Tungaloy CPMT080204 NS9530 indexable plate is an uncoated cermet grade, selected specifically for its sharp cutting edge and fine finish capabilities.

What are the critical dimensions to check for holder compatibility?
Check insert size (08), thickness (2.38 mm), relief angle (11°), included angle (80°) and the hole/countersink geometry; matching these with the holder ensures correct clamping and repeatability for the CPMT080204 NS9530.

Can this plate handle interrupted cuts?
The NS9530 finishing grade is optimised for continuous cuts and small depths of cut; for heavily interrupted machining a tougher grade or different chipbreaker is recommended instead of the CPMT080204 NS9530.

Which components make up the complete tool system for use with this insert?
A complete system includes the ISO-indexable insert, a matched external holder or boring bar, backing/shim or clamp set and replacement screws; specifying the CPMT080204 NS9530 together with the correct holder ensures stable performance and repeatable results.
