CNMG 090404 AH8015 — ISO rhombic turning insert by Tungaloy for turning applications

The CNMG090404 AH8015 Tungaloy insert is an ISO-standard rhombic turning insert with PVD-coated carbide, engineered for reliable performance in the machining of heat-resistant alloys and general turning tasks.

• PVD-coated carbide grade AH8015
• ISO rhombic CNMG 09 format
• 0.4 mm corner radius for precision
• Double-sided chipbreaker, through-hole fix

Consistent performance on heat-resistant alloys and mixed production

The PVD-coated AH8015 grade combines wear resistance with edge stability, making it well suited for the machining of heat-resistant alloys and other demanding materials. The coating promotes a controlled microgeometry at the cutting edge, which reduces adhesion and thermal softening during extended cycles. Such properties translate into fewer unplanned tool changes, a steadier surface finish and more predictable tool life — factors that improve throughput and help meet production targets without compromising component quality.

Easy integration into ISO tooling systems for productivity gains

Designed to the ISO CNMG form, this rhombic insert benefits from full compatibility with standard external and internal turning holders when the holder’s form, clearance angle, tolerance class, clamping method, size and thickness match. The double-sided chipbreaker extends the usable edge life, while the through-hole (cylindrical hole) enables secure clamping and straightforward indexing. These design choices support efficient chip control and rapid index changes, which together reduce downtime and simplify tool management in a production environment.

Practical edge geometry and handling guidance for reliable results

With a 0.4 mm corner radius and a 0° relief angle, the insert delivers a balance between fine finishing and moderate-strength cutting. The small radius assists in producing consistent surface quality on small to medium depth cuts, while the reputable grade helps maintain edge integrity under intermittent higher thermal loads. For best results, match the chipbreaker style and grade selection to workpiece stability and feed/speed strategy; adequate clamping and correct holder geometry are essential to exploit the insert’s full benefits in both roughing and finishing cycles.

FAQ

What materials is this insert optimised for?
The CNMG090404 AH8015 insert is optimised for heat-resistant alloys and general turning applications; the AH8015 grade provides balanced wear resistance and edge stability.

Can this insert be used for both external and internal turning?
Yes, the ISO rhombic format and through-hole clamping make the insert suitable for both external and internal turning when paired with the correct holder geometry.

How does the 0.4 mm corner radius affect the machining result?
A 0.4 mm corner radius provides a compromise between surface finish and edge strength, improving finish on lighter cuts while still tolerating moderate cutting forces.

What does the 0° clearance angle require from the toolholder?
A 0° clearance angle requires a holder designed to provide the correct relief and support; correct holder selection ensures stable cutting and prevents premature edge chipping.

Is the grade AH8015 suited to high-temperature cutting?
The PVD-coated AH8015 grade is specified for heat-resistant alloys and offers thermal stability and wear resistance suitable for higher temperature applications.
