CNMG 120408 AH8015 turning insert — PVD‑coated carbide, rhombic 80° (Tungaloy)

A robust CNMG120408 AH8015 ISO‑standard turning insert designed for external and internal turning of heat‑resistant alloys, combining edge stability with economical indexing.

• ISO‑standard rhombic insert CNMG 120408
• PVD‑coated carbide AH8015 for heat‑resistant alloys
• Double‑sided geometry with 0.8 mm corner radius
• Cylindrical‑hole fixing; compatible with ISO holders

Precision and compatibility for reliable turning

The ISO‑conformant rhombic geometry delivers a stable cutting edge with an 80° included angle that suits a wide range of turning tasks. Compatibility with clamping systems is determined by form, relief angle (0°), tolerance class, fixing method, size and thickness, so correct pairing with a matching holder is essential for repeatable results. The 4.76 mm plate thickness and 12 mm size provide a robust contact area that supports steady cutting forces and reduced vibration.

Balanced wear resistance for heat‑resistant alloys

The AH8015 grade is a PVD‑coated cemented carbide developed as a first choice for general machining of heat‑resistant alloys, offering a well balanced combination of wear resistance and edge stability. The coating increases surface hardness and reduces adhesion of workpiece material, which helps to maintain cutting performance and surface finish over longer engagement times. The double‑sided design further improves cost efficiency by allowing indexation of the second cutting edge once one side is worn.

Practical integration and secure clamping

Fixing is via a cylindrical hole that provides straightforward and secure seating in compatible ISO holders and boring bars. A complete system comprises the insert, a matching outer holder or boring bar, a support/ clamp set and replacement screws; selecting the correct chipbreaker and grade according to workpiece material, machining strategy and machine‑tool stability ensures predictable cycle times. Clear identification of the insert dimensions and the tolerance class simplifies procurement and reduces setup errors.

Improved process reliability and controlled costs

Economic advantages derive from the combination of double‑sided indexing and the balanced AH8015 grade: fewer insert changes, consistent component quality and less unplanned downtime. The rhombic form and the PVD‑coated carbide substrate support steady chip formation and surface integrity, which contributes to stable batch processing and lower total machining costs. For shops aiming to standardise turning operations, this offers a pragmatic route to higher throughput with maintained part quality.

FAQ

What materials is this insert intended for?
The CNMG120408 AH8015 Tungaloy insert is intended primarily for heat‑resistant alloys and offers a balanced performance between wear resistance and edge stability.

How does the AH8015 grade affect tool life?
The AH8015 PVD‑coated grade improves surface hardness and adhesion resistance, which contributes to longer effective tool life and more consistent surface finishes under typical turning conditions.

Is the insert compatible with my existing ISO holder?
Compatibility depends on holder form, relief angle, tolerance class, clamping method, insert size and thickness; verify these parameters against the CNMG120408 dimensions before fitting.

What is the benefit of the double‑sided geometry?
Double‑sided geometry allows indexing to the second cutting edge, reducing insert consumption per part and improving cost efficiency for repetitive turning operations.
