CNMG 120404 AH8015 — Indexable Turning Insert for Turning by Tungaloy

CNMG120404 AH8015 is an ISO‑standard rhombic insert designed for general turning of heat‑resistant alloys and a wide range of engineering materials.

• PVD-coated carbide grade AH8015
• 80° rhombic geometry with 0.4 mm radius
• Double-sided, cylindrical-hole clamping
• ISO-standard CNMG120404 for turning

High productivity for turning heat‑resistant alloys

The CNMG120404 AH8015 grade combines a PVD-coated surface with a wear‑resistant carbide substrate to offer balanced performance between edge stability and abrasion resistance. This makes the insert particularly suitable for the general turning of heat‑resistant and high‑temperature alloys, where cutting edge security and predictable tool life are crucial. The result is a stable cutting process with fewer interruptions and consistent component tolerances — a direct contribution to improved throughput and lower process costs.

Geometry and clamping ensure repeatable setup

The rhombic 80° geometry and double‑sided design permit two indexing positions per edge, extending usable life while maintaining cutting angles that support efficient chip formation. The insert features a cylindrical hole for proven clamping on ISO‑type holders; compatibility is defined by form, relief angle, tolerance class, fixation method, size and thickness. Choosing the correct holder and tightening torque secures repeatable positioning, which reduces setup time and ensures that the machining parameters translate reliably from trial cuts to production runs.

Coating and substrate deliver durable performance

The AH8015 designation signifies a PVD‑coated carbide engineered as a first choice for demanding general machining of temperature‑resistant alloys. The coating improves oxidation resistance and lowers flank wear, while the substrate preserves edge integrity under interrupted cuts. Together they provide a balance between wear resistance and fracture toughness, helping to avoid premature edge chipping and to maintain surface finish on the workpiece. This combination supports longer tool cycles and fewer insert changes during multi‑shift production.

Practical selection: chipbreaker and application advice

The insert’s double‑sided chipbreaker geometry is intended to suit both external and internal turning operations; select the chipbreaker and grade in accordance with workpiece material, machining stability and desired surface finish. For roughing choose a more robust cutting condition and larger depth of cut, while finishing benefits from reduced feed and optimised speed for surface quality. The ISO designation, rhombic shape and corner radius 0.4 mm aid in predictable transition between roughing and finishing steps, simplifying tool inventory management and process planning.

FAQ

What materials is this insert best suited for?
The CNMG120404 AH8015 insert is optimised for heat‑resistant alloys and general engineering steels; the PVD coating and carbide substrate provide a balance of wear resistance and edge stability for these materials.

How many usable edges does the insert provide?
With its double‑sided rhombic design the insert offers multiple indexing positions per side, allowing reuse of edges until the grade life is reached.

Which clamping system is required for this insert?
Clamping requires an ISO‑compatible holder designed for CNMG inserts and a cylindrical through‑hole; compatibility depends on holder form, tolerance class and fixation method.

Can this insert be used for both roughing and finishing?
Yes — the 0.4 mm corner radius and chipbreaker geometry permit flexible use across roughing and finishing operations when cutting data are adjusted accordingly.
