CNMG090408 AH8015 CNMG ISO rhombic turning insert for general turning – Tungaloy

The CNMG090408 AH8015 is an ISO-standard rhombic turning insert designed for versatile external and internal turning in demanding materials, offering a balanced mix of wear resistance and edge stability.

• PVD-coated carbide AH8015 grade
• ISO rhombic CNMG 09 insert
• 0.8 mm cutting edge radius
• Double-sided chipbreaker, with cylindrical hole

Reliable cutting performance for heat-resistant alloys

The PVD-coated AH8015 grade provides a balance between wear resistance and cutting-edge stability, making this insert well suited for machining heat-resistant alloys and other demanding materials. The combination of a PVD coating and a robust carbide substrate reduces flank wear and helps preserve surface finish over longer tool life. In practice, this means consistent component quality during extended production runs and fewer unscheduled tool changes, improving overall machining efficiency.

Designed for quick integration into ISO systems

Compatibility with standard holders is determined by geometry, clearance angle, tolerance class, fixation method, size and thickness, and the CNMG090408 conforms to ISO norms for straightforward replacement. The rhombic plate form and the cylindrical hole allow secure clamping in a matching external holder or a boring bar; the double-sided design offers economical indexing. The system approach—insert, holder or boring bar, shim/clamp and replacement screws—ensures predictable clamping forces and repeatable set-up in production.

Practical advantages in shop-floor use

The relatively large 0.8 mm corner radius and the plate thickness of 4.76 mm contribute to edge strength and vibration damping during heavier cuts, while the 0° clearance supports stable cutting geometry in typical turning operations. Users benefit from a good compromise between robustness and the ability to achieve acceptable surface finishes without complex parameter changes. The insert’s ISO CNMG form simplifies stock management by matching widespread holder families.

Clear benefits and user guidance

Selecting the correct chipbreaker and grade for the workpiece and operation is essential; the double-sided chipbreaker here is suitable for a wide range of feeds and depths of cut in turning. For applications that demand higher stability or when machining particularly abrasive alloys, pairing this insert with a rigid holder and optimised cutting parameters improves tool life and process security.

FAQ

What materials is this insert best suited for?
The CNMG090408 AH8015 insert is formulated for general machining of heat-resistant alloys and similar demanding materials, with the AH8015 PVD-coated carbide offering a balance of wear resistance and edge stability.

How is holder compatibility determined for this insert?
Compatibility depends on the insert form, clearance angle, tolerance class, fixation method, size and thickness; the ISO CNMG090408 designation ensures compatibility with standard CNMG holders and boring bars.

What are the key dimensional specifications to check before fitting?
Check the plate form (CNMG), corner radius (0.8 mm), thickness (4.76 mm) and the 80° included angle to ensure correct seating and clamping in the chosen holder.

Can the insert be indexed and reused?
Yes, the insert is double-sided with multiple usable edges; indexing provides economical use of the cutting material and predictable changeover.

What advantages does the PVD coating provide?
The PVD-coated AH8015 grade enhances surface hardness and wear resistance, improves flank wear behaviour and supports stable cutting performance during longer cycles.
