CNMG 090404 AH8015 Tungaloy indexable insert – ISO turning insert for general turning

The CNMG090404 AH8015 is a PVD‑coated carbide indexable turning insert designed for external and internal turning of heat‑resistant alloys and general machining tasks.

• PVD‑coated AH8015 grade
• ISO CNMG 090404 format
• Rhombic 80° geometry
• Double‑sided chipbreaker

Engineered for consistent turning performance

The insert is manufactured from carbide and finished with a PVD coating, the AH8015 grade providing a measured balance between wear resistance and cutting‑edge stability. This makes it a first choice for machining heat‑resistant alloys, where thermal and abrasive loads can shorten tool life. The PVD‑coated surface increases hardness and improves adhesion of the coating to the substrate, which in practical terms translates into fewer indexings and longer effective tool life. For operations where cycle time and reproducible results matter, the material and coating combination reduce flank wear and maintain dimensional consistency across a production run.

Precise geometry for predictable fit and cutting action

The ISO CNMG 090404 format denotes a rhombic insert with an 80° included angle and a 0° clearance specification; the corner radius is 0.4 mm, and the plate thickness is 4.76 mm. These geometric parameters determine cutting forces, surface finish and compatibility with ISO‑standard holders. Compatibility with a given holder is governed by insert form, clearance angle, tolerance class, clamping method, size and thickness; the presence of a cylindrical locating hole facilitates secure clamping. Choosing the correct chipbreaker and grade for the workpiece and machine rigidity ensures controlled chip formation and stable cutting, helping to avoid built‑up edge and improve repeatability.

Practical shop‑floor advantages and system integration

As part of an ISO insert system, the CNMG series works together with a matching external holder or boring bar, a shim/clamping set and replacement screws. The double‑sided chipbreaker increases the number of usable edges per insert, lowering consumable turnover and machine downtime. For small shops and production lines alike, the ability to index inserts quickly and restore cutting performance is a direct contributor to productivity. The insert is suitable for both finishing and general turning operations when the chipbreaker and grade selection are aligned with material and stability requirements, delivering a pragmatic blend of performance and economy in everyday machining.

FAQ

Which holders are compatible with this insert?
Compatibility is determined by insert form, clearance angle, tolerance class, clamping method, size and thickness; use holders specified for the ISO CNMG 090404 format to ensure proper fit with the CNMG090404 AH8015 indexable insert (SKU 6966080‑Tungaloy).

For which materials is the AH8015 grade intended?
The AH8015 PVD‑coated carbide grade is designed as a first choice for general machining of heat‑resistant alloys, offering a balance of wear resistance and cutting‑edge stability for demanding thermal and abrasive conditions.

What does the double‑sided chipbreaker mean in practice?
A double‑sided chipbreaker provides additional usable cutting edges before the insert must be replaced, improving on‑machine availability and reducing consumable changeover time for the CNMG090404 AH8015 inserts.

How should the insert be integrated into an existing tool system?
Integrate the insert with a matching external holder or boring bar, add the correct shim/clamping set and spare screws; ensure the holder accepts CNMG 090404 geometry and the chosen chipbreaker suits the machining stability and workpiece material.
