CNMG 090402 AH8015 – Indexable turning insert (ISO 090402) by Tungaloy

A CNMG090402 AH8015 indexable insert designed for general turning of heat‑resistant alloys and other demanding materials, supplied as an ISO‑standard rhombic insert for compatibility with standard holders

• ISO‑standard rhombic insert, 80° cutting angle
• PVD‑coated cemented carbide, AH8015 grade
• Double‑sided chipbreaker for versatile turning
• Compatible with standard clamping systems

Reliable edge life through material and coating

The combination of cemented carbide substrate and a PVD coating in the AH8015 grade delivers a balanced mix of wear resistance and edge stability. This grade is specified for the general machining of heat‑resistant alloys, where sustained hardness at elevated temperatures matters. The coating reduces adhesion and flank wear, which in turn supports predictable tool life and fewer unplanned interruptions. For production environments that value reproducibility, the graded hardness and coating chemistry translate into measurable process stability and consistent surface quality.

Geometry that improves process efficiency and chip control

A rhombic insert form with an 80° cutting angle and a 0° clearance specification provides robust cutting engagement and reduced radial deflection on the workpiece. The 0.2 mm corner radius contributes to a good compromise between edge strength and surface finish. The double‑sided chipbreaker is engineered to control chip shape across a range of feeds and depths of cut, reducing the frequency of chip‑related stoppages and facilitating safer, faster material removal. These geometry choices shorten cycle times by enabling higher material removal rates while maintaining surface integrity.

Broad applicability on the shop floor for consistent results

Designed as an ISO‑standard turning plate, the insert suits external and internal turning tasks where a durable cutting edge is required. The AH8015 grade has been optimised for heat‑resistant alloys but offers a balanced performance on a wide range of steels and alloys when paired with the correct chipbreaker and machining parameters. Choosing the correct chipbreaker and stable setup leads to higher productivity and lower cost per component, particularly in batch production and mixed‑lot manufacturing where flexibility and repeatability are important.

System compatibility, handling and replacement benefits

Compatibility with holders is determined by the ISO form, thickness (4.76 mm), size (09) and the clamping and tolerance class. The insert is supplied with a cylindrical hole for secure indexing and retention. System assembly consists of the ISO insert, a matching outside holder or boring bar, a support shim/clamping set and replacement screws. The standardised format simplifies stocking and reduces setup time, while the double‑sided design provides economical indexing and rapid replacement without adjustments to holder geometry.

FAQ

What materials is this insert best suited for?
The CNMG090402 AH8015 insert and its AH8015 PVD coating are specified as a first choice for machining heat‑resistant alloys, while offering balanced performance on a range of steels and similar materials when used with the appropriate chipbreaker.

Is the insert compatible with standard ISO holders?
Yes; the insert conforms to the ISO 090402 form and fits holders and boring bars that accept CNMG‑format plates with a 4.76 mm thickness and the corresponding clamping system.

How does the double‑sided chipbreaker benefit production?
A double‑sided chipbreaker provides two usable cutting edges, reliable chip formation across varied cuts and easier indexing, which supports uninterrupted production and improves cost efficiency per edge.

What does the 0.2 mm corner radius mean for surface finish?
A 0.2 mm corner radius offers a compromise between edge strength and surface finish: it improves robustness against edge chipping while still delivering good surface quality for many turning tasks.

Can this insert be used for internal turning operations?
Yes; the rhombic shape and the standard hole design allow use in both external and internal turning when mounted in the correct holder and when machining parameters are adjusted for tool reach and rigidity.

Which system components are required to mount the insert?
Mounting requires a compatible outside holder or boring bar, a support shim/clamping set and the correct replacement screws; the ISO‑standard dimensions ensure interchangeability.
