CNMG 120408 AH8015 indexable insert – 80° rhombic geometry for turning (Tungaloy)

CNMG 120408 AH8015 is an ISO-standard indexable insert designed for versatile external and internal turning in industrial machining.

• ISO-standard rhombic 80° geometry
• PVD-coated carbide grade AH8015
• Double-sided chipbreaker for controlled chips
• Cylindrical through-hole for secure fastening

Predictable cutting behaviour from stable 80° geometry

The 80° rhombic geometry provides a reliable compromise between strength and accessibility, making it suitable for both external and internal turning operations. A robust approach angle reduces bending loads on the insert and the holder, which stabilises cutting conditions and improves repeatability. The corner radius 0.8 mm allows for light finishing cuts with good surface quality while maintaining edge strength when encountering variable material properties.

Durable PVD-coated carbide balanced for heat-resistant alloys

The PVD-coated carbide (grade AH8015) is developed as a first choice for general machining of heat-resistant alloys. The coating enhances wear resistance at elevated temperatures while the carbide substrate preserves edge stability, resulting in longer effective tool life under challenging thermal loads. This balance reduces downtime for insert changes and supports higher productivity on tougher materials.

Cost-effective indexing and secure clamping for production use

A double-sided chipbreaker design increases the number of usable cutting positions and contributes to predictable chip formation, which simplifies chip handling and machine enclosure management. The cylindrical through-hole ensures positive and secure fixing in a compatible ISO holder; compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness. This system approach reduces setup complexity and supports efficient tool inventory management.

Practical guidance for selection and process integration

When integrating this insert into a tooling system, select the chipbreaker and grade to match the workpiece material and the intended machining stability. The insert is supplied as part of an ISO-system: indexable insert, a suitable external holder or boring bar, clamping seat and replacement screws form the complete assembly. For consistent results, ensure holder rigidity and correct clamping torque; consistent set-up preserves the coating performance and maintains the expected surface finish.

FAQ

What materials is this insert suited for?
The CNMG 120408 AH8015 insert from Tungaloy is primarily intended for machining heat-resistant alloys and other demanding steels where a balance of wear resistance and edge stability is required.

How does the double-sided chipbreaker benefit production?
A double-sided chipbreaker increases the number of usable cutting positions and promotes controlled chip formation, which improves process reliability and reduces tooling cost per machined part with the CNMG 120408 AH8015.

Is the insert compatible with standard ISO holders?
Yes, the CNMG 120408 conforms to ISO dimensions; compatibility with a holder depends on the holder’s form, clearance angle, tolerance class, fastening method, size and thickness.

What does the 0.8 mm corner radius mean for surface finish?
A 0.8 mm corner radius offers a compromise between edge strength and surface finish, enabling light finishing cuts with improved surface quality while maintaining robustness.
