CNMG 120404 AH8015 indexable insert for turning – Tungaloy

CNMG120404 AH8015 Tungaloy indexable insert for ISO-standard external and internal turning applications, engineered for heat-resistant alloys and general-purpose machining.

• PVD-coated carbide AH8015 for heat-resistant alloys
• ISO CNMG120404 geometry, 80° rhombic form
• Double-sided chipbreaker for versatile turning
• Cylindrical hole; 0.4 mm corner radius

Consistent cutting performance with high-temperature alloys

The PVD-coated carbide grade AH8015 is balanced to deliver both wear resistance and edge stability in the machining of heat-resistant alloys. The coating increases resistance to thermal and abrasive wear, so the insert sustains stable cutting behaviour over longer tool life. This results in fewer insert changes and predictable process windows, supporting higher uptime and lower overall production costs. The performance is particularly relevant where a combination of surface quality and dimensional consistency is required in serial turning operations.

Secure fit and standardised geometry for easy tool selection

The ISO-standard profile and 80° rhombic shape ensure compatibility with a wide range of external holders and boring bars when the holder matches form, clearance angle, tolerance class, fastening and size. The insert is supplied with a cylindrical hole, simplifying clamping and alignment in standard ISO seats. The 0.4 mm radius offers a compromise between corner strength and achievable surface finish, making the insert suitable for both roughing and light finishing when combined with the correct holder stiffness and cutting data. Clear, standardised dimensions reduce setup time and support repeatable results across tool changes.

Reliable chip control and economical machining

The double-sided chipbreaker design supports controlled chip formation across typical turning conditions, improving evacuation and reducing the risk of chip-related interruptions. Being double-sided, the insert can be indexed to present a fresh cutting edge after wear, which increases the number of utilisable edges per insert and improves cost-efficiency. Combined with the AH8015 substrate, this configuration contributes to stable cutting forces and consistent surface quality, which in turn helps to maintain process reliability in demanding production environments.

FAQ

What materials is this insert suitable for?
The CNMG120404 AH8015 insert is designed primarily for heat-resistant alloys and general-purpose turning; the AH8015 grade balances wear resistance and edge stability for such materials.

How does the chipbreaker affect machining?
The double-sided chipbreaker on the insert improves chip formation and evacuation, which supports uninterrupted turning operations and consistent surface quality.

Can the insert be used in any CNMG holder?
Compatibility depends on matching the holder to the insert geometry, clearance angle, tolerance class, fastening method, size and thickness; the ISO designation facilitates selection of compatible holders.

How many usable edges does the insert offer?
The insert features a double-sided design, enabling indexing to expose fresh cutting edges and thus increasing the number of available edges per insert.

What role does the 0.4 mm corner radius play?
A 0.4 mm radius enhances corner strength while still allowing fine surface finishes; it provides a balance between robustness and the ability to achieve tighter surface specifications.
