CNMG 090402 AH8015 Turning indexable insert — rhombic 80° (Tungaloy)

The CNMG 090402 AH8015 is an ISO‑standard rhombic turning indexable insert engineered for external and internal turning, offering a robust PVD‑coated carbide grade suited to heat‑resistant alloys.

• PVD-coated carbide grade AH8015
• 80° rhombic geometry for stable cuts
• Double-sided chipbreaker for chip control
• 0.2 mm corner radius for finishing

High productivity through balanced wear resistance and edge stability

The AH8015 PVD‑coated carbide provides a deliberate balance between wear resistance and cutting-edge stability, making it a solid choice for the general machining of heat‑resistant alloys. The coating enhances flank wear performance at elevated temperatures while the carbide substrate maintains edge integrity under intermittent cutting loads. This combination reduces insert changes and contributes to more predictable tool life, which increases machine uptime and lowers unit costs per component.

Secure clamping and standardised geometry for easy integration

Built to the ISO CNMG form, the insert features an 80° rhombic geometry and a cylindrical hole for positive axial and radial positioning. The hardened‑centre hole and standardised form ensure compatibility with a wide range of external holders and boring bars when the holder’s form, clearance, tolerance class, fastening and thickness match the insert. The specified 4.76 mm thickness and 0.2 mm corner radius help to define the cutting engagement and are decisive when selecting a holder for repeated, vibration‑controlled turning.

Reliable chip control for consistent surface quality

The double-sided chipbreaker topology supports controlled fragmentation and evacuation of chips across a range of feeds and depths, aiding process stability and surface finish. A modest 0.2 mm corner radius provides a compromise between smooth finishing and edge strength; it limits burr formation while preserving edge robustness during interrupted cuts. For operators unfamiliar with chipbreaker geometry, its role is to shape the chip curl and reduce the risk of long, entangling swarf that can interrupt automated machining.

Practical system considerations and application range

This insert is supplied as part of an ISO turning system consisting of the insert, a matching external holder or boring bar, pads/clamping kit and replacement screws. The AH8015 grade is presented as a first choice for the general machining of heat‑resistant alloys, offering broad material coverage and stable chip formation. When specifying tooling for a process, match the chipbreaker and grade to the workpiece material, machining operation and machine stability to achieve the expected productivity gains.

FAQ

What materials is this insert best suited for?
The CNMG 090402 AH8015 insert is optimised for the general machining of heat‑resistant alloys; the AH8015 PVD coating and carbide substrate balance wear resistance and edge stability for such materials.

How does the 0.2 mm corner radius affect surface finish?
A 0.2 mm corner radius on the CNMG 090402 insert supports improved surface quality while retaining sufficient edge strength for interrupted or semi‑finishing cuts.

Is the insert reversible or single‑use per side?
The CNMG 090402 is double‑sided with a reversible geometry; each indexed face offers the same chipbreaker and cutting edge for multiple uses until wear criteria are met.

What should be considered when selecting a holder for this insert?
Select a holder that matches the ISO CNMG form: the holder must align in form, clearance angle, tolerance class, fastening method, insert size and thickness to ensure secure clamping and repeatable cutting geometry.

Does the AH8015 grade require special cutting parameters?
AH8015 is designed for a broad range of cutting conditions in heat‑resistant alloys; adjust cutting speed and feed according to machine rigidity and material hardness to exploit the grade’s wear resistance and edge stability.
