CNMG 090308 NS9530 — Turning insert (ISO CNMG), uncoated cermet, Tungaloy

CNMG090308 NS9530 is a rhombic ISO turning insert designed for fine finishing of steel under continuous-cut conditions and small depths of cut

• ISO‑standard CNMG 090308 geometry
• Uncoated cermet grade NS9530 for fine finishing
• Low cutting forces and high surface finish
• Double-sided insert with cylindrical hole

Reliable finishing for continuous turning and fine surfaces

The CNMG090308 NS9530 insert is engineered as a finishing grade for steel, combining a sharp cutting edge with low cutting forces to reduce chatter and improve stability during continuous cuts. The uncoated cermet grade NS9530 offers a predictable wear pattern and maintains a clean cutting edge, which directly translates into a high surface finish and reduced need for subsequent dressing or rework. For operations requiring consistent part-to-part quality, this geometry supports repeatable results with small depths of cut.

Quick holder compatibility and reduced machine downtime

The ISO rhombic form ensures straightforward interchangeability with standard CNMG holders; compatibility depends on geometry, relief, tolerance class, fastening, size and thickness. The insert has an included angle of 80° and a relief angle of 0°, with a plate thickness of 3.18 mm and a corner radius of 0.8 mm, which aids in predictable tool behaviour. The cylindrical hole provides reliable clamping and rapid indexation, so tool changes become faster and setup times are minimised, improving overall productivity in batch or single‑piece production.

Stable chip control and productive cutting strategy

Equipped with a double-sided arrangement and a double-sided chipbreaker, the insert supports two usable cutting edges and improved chip formation. Selecting the correct chipbreaker and grade according to the workpiece material, machining method and system rigidity is essential: a suitable chipbreaker ensures stable evacuation, reduces thermal load on the insert and supports continuous operation. The tooling system typically comprises the ISO turning insert, a matching external holder or boring bar, a support pad/clamping set and replacement screws — arranging these components optimally enhances process reliability.

Application guidance for efficient finishing and tool life

As a finishing solution, the insert is best applied to operations with small radial or axial engagement and stable machine conditions; this setup exploits the NS9530 grade’s ability to maintain a sharp cutting edge and deliver consistent surface integrity. The combination of ISO conformity and the finishing cermet grade supports predictable tool performance, allowing planning of tool indexing intervals and spare‑part provisioning. For complex setups or borderline materials, consultation on holder choice and chipbreaker selection helps to maximise the insert’s productive life and minimise cycle variability.

FAQ

What materials is this insert suitable for? The CNMG090308 NS9530 insert is a finishing grade for steel, optimised for continuous cuts and small depths of cut to achieve a high surface finish.

How many cutting edges are available per insert? The insert is double-sided, providing two usable cutting edges and enabling economical indexation.

Which geometry and angles does the insert use? The geometry is ISO CNMG with an included angle of 80° and a relief angle of 0°, suited for standard CNMG holders.

Is the insert supplied with a chipbreaker? Yes, the product features a double-sided chipbreaker; selecting the correct chipbreaker and grade is recommended based on material and machining stability.

How is the insert fastened in the holder? The insert comes with a cylindrical hole for secure clamping; compatibility with a holder depends on form, tolerance class, fastening method, size and thickness.

Can this insert be used for heavy roughing operations? The NS9530 grade is a finishing cermet intended for low cutting forces and fine surface quality; it is not designed for aggressive roughing cuts.

What is included in the tooling system for this insert? A complete system typically includes the ISO insert, a matching external holder or boring bar, a support pad/clamping set and replacement screws to ensure correct mounting and stability.
