CNMG 120408 NS9530 – CNMG turning insert, uncoated cermet (Tungaloy)

The CNMG120408 NS9530 is an ISO‑standard, rhombic turning insert designed for fine finishing of steel in continuous turning operations and for applications that prioritise surface integrity and low cutting forces.

• ISO‑standard CNMG 120408 rhombic insert
• NS9530 uncoated cermet for fine finishing
• Double‑sided chipbreaker with cylindrical hole
• 0° relief angle and 80° cutting edge angle

Achieve consistently superior surface quality

The uncoated cermet grade NS9530 is formulated for finishing passes on steel where a sharp cutting edge and low cutting forces are essential. This substrate delivers a fine micro‑edge that reduces built‑up edge and improves the surface finish on continuously fed cuts. In practical terms, the combination of the rhombic CNMG geometry and the cermet cutting composition enables reduced post‑processing and more consistent part tolerances, which benefits batch production and quality‑sensitive components.

Faster, more predictable cycle times for finishing operations

A double‑sided chipbreaker design lowers unit cost by enabling two effective cutting edges per insert and helps control chips during low to moderate depth cuts. The insert’s geometry — an 80° wedge angle with a 0° relief angle — supports stable contact with the workpiece, promoting steady cutting forces and predictable tool life. By selecting this grade for finishing, shops can reduce rejects and maintain higher throughput thanks to repeatable performance and fewer interruptions for manual adjustments.

Seamless integration into ISO‑based turning systems

Compatibility with ISO holders is determined by form, relief angle, tolerance class, fixation, size and thickness; the CNMG family is widely supported across standard carriers. The CNMG120408 insert features a 12 mm inscribed circle, 4.76 mm thickness and a 0.8 mm corner radius, with a cylindrical mounting hole for secure clamping. Selecting the correct chipbreaker and grade to match workpiece material and machine stability ensures the insert delivers the anticipated surface quality and economy in production environments.

FAQ

What materials is this insert suitable for?
The CNMG120408 NS9530 insert is optimised for finishing on steel, offering a sharp cutting edge and low cutting forces suitable for continuous turning operations.

Can the insert be used on reduced‑power machines?
Yes, the NS9530 cermet grade produces low cutting forces, making the insert suitable for machines with limited spindle power when used in appropriate finishing parameters.

How many usable edges does the insert provide?
This rhombic CNMG insert is double‑sided, providing two usable cutting edges before indexing or replacement is required.

Which holder features must be checked for compatibility?
Compatibility depends on holder form, relief angle, tolerance class, fixation method, size and thickness; verify these specifications with the intended ISO‑standard holder before fitting the CNMG120408.

What performance benefits can be expected in production?
Expect improved surface finish, reduced manual rework, and predictable tool life when the NS9530 grade and the CNMG geometry are matched to the workpiece and process stability.
