CNMG 120408 AT9530 Tungaloy — ISO CNMG120408 indexable insert for Turning

The CNMG120408 AT9530 indexable insert is an ISO‑format, rhombic turning insert optimised for finishing and light turning of steel, offering a fine surface quality and steady wear behaviour.

• Coated cermet grade AT9530 for fine finishes
• 0.8 mm corner radius for reduced edge chipping
• Rhombic CNMG form with 80° included angle
• Double‑sided insert with cylindrical hole

Optimised finishing performance and consistent wear

The coated cermet AT9530 grade is developed for finishing and light turning of steel and delivers a noticeable improvement in surface finish and wear uniformity compared with uncoated grades. Cermet combines ceramic hardness with metallic toughness; the coating further stabilises the cutting edge, reducing flank wear and maintaining dimensional accuracy over longer tool lives. For production environments this means fewer indexings and more predictable intervals between tool changes, contributing to lower overall machining costs and improved process stability.

Stable geometry for vibration control and straightforward integration

The rhombic CNMG geometry with an 80° included angle and 0° relief provides a predictable cutting behaviour and good edge support when paired with suitable ISO turning holders. The plate thickness of 4.76 mm and the cylindrical hole ensure secure clamping and repeatable positioning in standard holders; compatibility is determined by form, free angle, tolerance class, fastening, size and thickness. A 0.8 mm corner radius helps to absorb peak cutting forces, reducing the risk of edge chipping and enabling confidence on semi‑finishing passes while maintaining the desired surface quality.

Cost‑effective handling and application guidance for workshops

As a double‑sided insert the CNMG120408 reduces cost per cutting edge and supports continuous production without frequent index changes. The integrated double‑sided chipbreaker is selected for stable chip control during light steel machining; for different materials or more aggressive cutting conditions a different chipbreaker or grade may be preferable. For practical selection, match the chipbreaker and grade to the workpiece material and stability of the setup — this ensures the best balance of tool life, component quality and process efficiency.

FAQ

Is this insert suitable for finishing steel components?
Yes. The CNMG120408 AT9530 is engineered for finishing and light turning of steel; the coated cermet grade promotes a fine surface finish and even wear during operations.

How does the AT9530 grade differ from conventional carbide?
AT9530 is a coated cermet grade combining ceramic hardness with improved edge life and coating benefits; it offers better surface quality and controlled wear compared with standard carbide grades when used for finishing.

Can the insert be used in any CNMG holder?
The insert follows ISO CNMG120408 dimensions, but compatibility depends on holder form, free angle, tolerance class, fastening and thickness; check the holder specification against the insert dimensions before mounting.

How many cutting edges are available per insert?
This is a double‑sided CNMG insert, providing multiple usable edges; actual edge count depends on how the insert is indexed during use.
