CNMG090404 AH8015 ISO rhombic turning insert — PVD‑coated carbide by Tungaloy

The CNMG090404 AH8015 is an ISO rhombic indexable insert designed for external and internal turning, optimised for machining heat‑resistant alloys with stable chip control.

• PVD-coated carbide for heat-resistant alloys
• ISO rhombic CNMG geometry, 80° cutting edge
• Double-sided chipbreaker for stable chip control
• Cylindrical hole and 0.4 mm corner radius

Maximised productivity with consistent edge life

The combination of a PVD‑coated surface and a robust carbide substrate means prolonged service intervals and reproducible component quality. The selected coating grade AH8015 provides a balanced mix of wear resistance and edge stability, which reduces the frequency of insert changes and supports uninterrupted production runs. This results in measurable cycle‑time savings and fewer tool interventions when machining demanding alloys.

Seamless integration into ISO tool systems

Designed to ISO dimensions, the CNMG090404 form ensures compatibility with standard holders when form, relief angle, tolerance class, fastening and thickness are matched. The 80° lead angle and 0° relief are well suited to general turning tasks, while the 0.4 mm corner radius helps achieve good surface integrity without excessive cutting forces. The insert thickness of 4.76 mm and the cylindrical hole guarantee secure clamping and positional repeatability in the toolholder.

Reliable chip control for demanding materials

The double‑sided chipbreaker geometry was chosen to manage chips effectively during both external and internal turning. For heat‑resistant alloys, controlled chip formation reduces built‑up edge and stabilises cutting temperatures, supporting longer tool life and more consistent surface finishes. The design delivers predictable chip flow, facilitating automated swarf handling and safer machining cycles.

FAQ

What materials is this insert best suited for?
The CNMG090404 AH8015 insert is optimised for heat‑resistant alloys, offering a balance of wear resistance and cutting-edge stability for demanding turning tasks.

Which geometry and dimensions define the insert?
The insert has CNMG090404 geometry (size 09), a thickness of 4.76 mm, a corner radius of 0.4 mm and an 80° lead angle.

Is the insert reversible or single‑use?
This is a double‑sided indexable insert, so each side can be rotated into the cutting position to extend usable life before disposal.

What coating and substrate are used?
The insert features a PVD coating in grade AH8015 on a carbide substrate, chosen for a balance of wear resistance and edge stability.

How is compatibility with a toolholder ensured?
Compatibility depends on matching the ISO form, relief angle, tolerance class, fastening method, size and thickness between holder and insert; if in doubt, Metav Werkzeuge can advise on the correct combination.
