CNMG090408 AH8015 ISO turning insert for turning by Tungaloy — rhombic 09, 0.8 mm corner radius, 80°

A CNMG090408 AH8015 insert designed for ISO‑compliant external and internal turning, optimised for heat‑resistant alloys and everyday workshop productivity

• ISO‑standard CNMG090408 insert, 80° included angle
• AH8015 PVD-coated carbide for heat-resistant alloys
• Rhombic 09 form with 0.8 mm corner radius
• Double-sided chipbreaker, cylindrical hole, 4.76 mm thick

Higher productivity through balanced grade and coating

The AH8015 grade is a PVD‑coated carbide engineered as a first choice for the machining of heat‑resistant alloys, offering a balanced combination of wear resistance and edge stability. This balance reduces unexpected tool changes and supports longer uninterrupted machining cycles, which leads to improved throughput. The coating enhances resistance to adhesive and abrasive wear at elevated temperatures, so the insert maintains performance where uncoated grades would deteriorate quickly.

Simple integration with ISO tooling systems

Manufactured to the ISO series format, the insert matches the critical parameters that determine holder compatibility: form, relief angle, tolerance class, clamping style, size and thickness. The rhombic 09 geometry with an 80° included angle and 0° free angle makes the component straightforward to fit into many standard external holders and boring bars. The cylindrical hole facilitates secure clamping and repeatable positioning, while the 4.76 mm thickness provides the mechanical support needed for stable cutting in interrupted or heavy cuts.

Consistent chip control and surface quality

The double‑sided chipbreaker reduces chip size and stabilises the cutting process, resulting in more consistent surface finishes and less time spent on secondary operations. The 0.8 mm corner radius strengthens the cutting edge, improving edge life under higher feed rates and more demanding conditions. Where fine surface finish is essential, selecting appropriate feeds and a matching chipbreaker style will deliver the required balance between tool life and finish quality.

Practical application guidance for workshop use

Intended primarily for turning, the insert performs well in both external and internal operations when paired with a suitable external holder or boring bar and properly selected cutting parameters. The system approach—insert, holder, clamp set and replacement screws—ensures secure assembly and repeatable results. For shops processing heat‑resistant alloys, the AH8015 choice reduces rework and increases uptime; for other materials, choose the chipbreaker and cutting data matched to the workpiece for optimal results.

FAQ

What materials is the insert optimised for?
The AH8015 grade on the CNMG090408 insert is optimised for machining heat‑resistant alloys; matching chipbreaker and cutting data is recommended when processing other materials.

What effect does the 0.8 mm corner radius have on machining?
A 0.8 mm corner radius increases edge strength and tool life under heavier feeds, while producing a slightly more robust surface finish compared with smaller radii.

Is this insert reversible and how is it clamped?
Yes, the insert is double‑sided and designed for reversible use; the CNMG090408 AH8015 turning insert features a cylindrical hole for secure, repeatable clamping.

How is compatibility with toolholders determined?
Compatibility is determined by form, free angle, tolerance class, clamping method, size and thickness; the ISO‑compliant CNMG090408 designation aids correct holder selection.

What does the designation CNMG090408 indicate?
The designation indicates a rhombic CNMG geometry with an insert size 09, a 0.8 mm corner radius and the 04× thickness series (4.76 mm), matching ISO standards for turning inserts.
