CNMG120408 AH8015 ISO turning insert — PVD-coated carbide, cylindrical-hole fastening — Tungaloy

A CNMG120408 AH8015 indexable insert designed for ISO-compliant external and internal turning, optimised for heat-resistant alloys and general turning operations

• PVD-coated carbide AH8015 grade
• 80° rhombic geometry for stable cutting
• 0.8 mm corner radius for versatility
• Cylindrical hole for secure clamping

Reliable cutting performance for demanding alloys

The combination of a PVD-coated carbide substrate and the AH8015 grade provides a balance between wear resistance and edge stability, making this insert suitable for operations where material heat resistance matters. The indexable insert geometry complies with ISO standards, ensuring predictable seating and repeatable orientation in a suitable holder. When paired with an appropriate external or internal holder and the correct clamp and screw set, the construct delivers consistent chip control and surface finish on a wide range of workpiece alloys, reducing unplanned interruptions and improving process efficiency.

Stable clamping and proven geometry reduce setup effort

The rhombic plate form with an 80° cutting angle and a cylindrical hole fastening system ensures reliable location and secure clamping in compatible toolholders. The 0.8 mm corner radius offers a practical compromise between edge strength and fine finishing capability, allowing fewer tool changes across mixed batches. Since compatibility depends on holder form, relief angle, tolerance class, fastening and plate thickness, selecting a matched holder and fasteners is essential to exploit the insert’s full potential and maintain machining stability.

Practical advantages for workshop productivity

With a plate thickness of 4.76 mm and standard ISO sizing, the insert supports straightforward tool management and stockkeeping. The double-sided chipbreaker and symmetrical geometry enable indexable use of both cutting edges, extending useful tool life per insert and lowering tooling cost per component produced. Clear identification by ISO designation simplifies replacement and reduces the risk of incorrect tool selection, while the PVD surface treatment improves resistance to built-up edge and moderate heat exposure during intermittent and continuous turning cycles.

FAQ

What materials is this insert suited for?
The CNMG120408 AH8015 insert (Tungaloy, indexable turning insert, SKU 6793720-Tungaloy) is specified for general machining of heat-resistant alloys and similar materials where a balance of wear resistance and edge stability is required.

Is the insert reversible and how many cutting edges are available?
The rhombic, double-sided design provides multiple usable edges; the chipbreaker arrangement allows indexing of additional edges to extend the insert’s service life.

Which holders are compatible with this ISO insert?
Compatibility is defined by ISO holder form, relief angle, tolerance class, fastening and thickness; matching an ISO external or internal turning holder that accepts CNMG plates with a cylindrical-hole fastening will ensure correct seating and clamping.

How does the PVD coating affect performance?
The PVD-coated carbide surface enhances wear resistance and reduces built-up edge tendency during turning operations, offering improved tool life and more consistent surface finish under varying cutting conditions.

What benefits does the 0.8 mm corner radius deliver?
The 0.8 mm corner radius balances edge strength with finishing capability, enabling versatility across a range of turning tasks from medium material removal to semi-finishing passes.
