CNMG 090408 AH8015 indexable turning insert — Tungaloy, PVD‑coated carbide, 80° geometry

The CNMG 090408 AH8015 is an ISO‑standard indexable insert for general turning, designed primarily for machining heat‑resistant alloys and other demanding materials

• ISO‑standard CNMG insert, 090408 size
• PVD‑coated carbide grade AH8015
• Double-sided chipbreaker for stable cutting
• 0.8 mm corner radius with cylindrical hole

Predictable performance through a balanced carbide grade

The PVD‑coated carbide grade AH8015 delivers a deliberate compromise between wear resistance and edge stability, making it a dependable choice for sustained turning operations of heat‑resistant alloys. The thin PVD layer increases surface hardness and reduces thermal softening at the cutting edge, which translates into extended tool life and fewer interruptions for tool changes. Combined with a double‑sided chipbreaker, the geometry supports stable chip formation under varying cutting conditions, helping to maintain surface finish quality and process consistency.

ISO compatibility and design for secure clamping

The rhombic 80° geometry and ISO CNMG form ensure interchangeability across compatible holders; compatibility depends on form, clearance angle, tolerance class, clamping method, size and thickness. This insert features a 0° clearance angle, a 0.8 mm corner radius and a cylindrical hole for positive locating and straightforward clamping. The plate thickness of 4.76 mm and the size designation 09 match common ISO toolholders, reducing the risk of mismatch and minimising setup time. Verifying holder compatibility by comparing these parameters before assembly supports reliable seating and repeatable cutting forces.

Practical selection advice to increase productivity

For best results in turning and internal operations, match the chipbreaker style and grade to the workpiece material, machining type and machine rigidity; the double‑sided breaker offers flexibility for both roughing and light finishing passes. Selecting the correct holder, underlay/washer and replacement screws as part of the system reduces vibration and improves tool life. The result is a more predictable process, fewer scrapped parts and improved throughput — advantages that contribute directly to lower part costs and higher shopfloor efficiency.

FAQ

What materials is this insert best suited for?
The CNMG 090408 AH8015 insert from Tungaloy is optimised for heat‑resistant alloys and general‑purpose turning where a balance between wear resistance and edge stability is required.

How does the PVD coating affect performance?
The PVD coating on the AH8015 grade increases surface hardness and thermal resistance, improving wear performance and reducing built‑up edge compared with uncoated grades.

Which toolholder parameters must be checked for compatibility?
Ensure the toolholder matches the CNMG form, the 80° geometry, the plate thickness (4.76 mm), size 09 and the clamping system that accommodates a cylindrical hole and the required tolerance class.

Can the insert be used for both roughing and finishing?
Yes; the double‑sided chipbreaker provides versatility that allows one face for heavier cuts and the other for finishing passes, subject to correct feed and speed selection.

Is the 0.8 mm corner radius suitable for finishing work?
A 0.8 mm corner radius offers a compromise between strength and surface finish; it provides a robust edge for medium feeds while still allowing acceptable surface quality in many finishing scenarios.
