CNMG 090402 AH8015 Tungaloy turning insert for turning

The CNMG090402 AH8015 Tungaloy insert is a rhombic, ISO‑standard turning insert designed for precision external and internal turning of heat‑resistant alloys.

• PVD‑coated carbide grade AH8015
• Double‑sided chipbreaker for versatility
• Rhombic CNMG shape, 80° cutting angle
• Cylindrical hole, secure face clamping

Efficient machining of heat‑resistant alloys with balanced wear resistance

The PVD‑coated AH8015 grade combines wear resistance with edge stability, making it suitable as a first choice for general machining of heat‑resistant alloys. The substrate is carbide, optimised to provide consistent performance under elevated temperatures and interrupted cuts. For production environments where tool life and repeatability matter, the coated surface reduces adhesive wear and assists in maintaining dimensional accuracy over longer tool life cycles. The coating also helps to lower built‑up edge formation, which in turn supports stable surface finish and predictable tool change intervals.

Geometry and clamping that support reliable turning processes

The insert’s rhombic CNMG form with an 80° cutting angle and a 0.2 mm corner radius delivers a compromise between strength and accessibility into tight contours. The plate is double‑sided, offering two usable cutting edges per side, and features a cylindrical hole for secure face clamping on compatible holders. A 0° clearance angle and a plate thickness of 4.76 mm provide rigidity under higher cutting forces. These geometric details determine the contact mechanics with the workpiece and should be matched to the chosen holder and clamping system to ensure optimal repeatability and vibration damping during turning.

System considerations and selecting the right chipbreaker

In practice, successful turning requires selection of a chipbreaker and grade that suit the workpiece material, machining mode and machine stability. The CNMG format integrates into an ISO‑compliant system comprising an external holder or boring bar, shim/clamp sets and replacement screws; compatibility is governed by form, clearance angle, tolerance class, fixation and plate dimensions. The double‑sided chipbreaker offers flexibility across a range of cutting conditions, while the PVD coating assists with thermal barriers in sustained cuts. For customers less familiar with coating types, PVD (physical vapour deposition) is a thin, hard surface layer that improves wear resistance without substantially altering the insert geometry.

FAQ

What materials is this insert intended for?
The CNMG090402 AH8015 Tungaloy insert is specified for general machining of heat‑resistant alloys; the AH8015 grade balances wear resistance and edge stability for these materials.

Is the insert compatible with standard CNMG holders?
Compatibility is determined by plate form, clearance angle, tolerance class, fixation, size and thickness; the CNMG090402 follows ISO dimensions and fits holders designed for CNMG inserts.

How many cutting edges are available per plate?
The plate is double‑sided with indexed edges, offering multiple usable cutting edges to maximise tool economy during production.

What does the PVD coating provide?
PVD coating on the AH8015 grade improves wear resistance and reduces adhesive wear, which supports longer tool life and a more stable surface finish in challenging cutting conditions.

Which chipbreaker should be chosen for interrupted cuts?
For interrupted cuts, select a chipbreaker and grade aligned with the workpiece stability and cutting parameters; the double‑sided chipbreaker on this plate offers flexibility across different turning tasks.
