CNMG120408 AH8015 ISO CNMG 120408 turning insert by Tungaloy — PVD‑coated carbide, 0.8 mm radius

A CNMG120408 AH8015 ISO turning insert engineered for general turning applications, offering a balanced compromise between wear resistance and cutting edge stability for heat‑resistant alloys.

• PVD‑coated carbide grade AH8015
• 0.8 mm nose radius for precise finishing
• Double‑sided with cylindrical hole for clamping
• ISO rhombic 80° geometry, 4.76 mm thickness

Balanced performance for heat‑resistant alloys

The insert's core is a PVD‑coated carbide grade designed as a first choice for general machining of heat‑resistant alloys. The thin, hard PVD layer increases wear resistance while preserving the integrity of the cutting edge, which translates into longer tool life under elevated temperatures and more consistent component tolerances. This combination reduces unplanned tool changes and supports a more predictable production rhythm, delivering a clear economic advantage through improved process stability and less scrap.

Geometry that delivers repeatable surface quality

With a 0.8 mm nose radius and an 80° rhombic form, the insert provides a stable cutting geometry that favours a fine surface finish while maintaining strength at the cutting edge. The 4.76 mm plate thickness increases rigidity in interrupted and heavy cuts, and the double‑sided design offers indexing capability for extended service life. A cylindrical hole ensures secure clamping in ISO‑standard holders, reducing vibration and improving repeatability between tool changes. These features combine to help maintain cycle times and reduce rework.

Workshop integration and application guidance

The insert is part of an ISO‑standard system comprising the indexable plate, a matched external holder or boring bar, a seating shim and the correct clamping screw. Compatibility with a given holder depends on form, clearance angle, tolerance class, fixation method, size and thickness; selecting the correct chipbreaker and grade for the workpiece material and machining conditions is essential. For external and internal turning operations the balanced AH8015 grade supports reliable chip control and consistent cutting performance, contributing to higher productivity and reduced downtime when integrated into a well‑matched tooling system.

FAQ

Is this insert compatible with standard CNMG holders?
Compatibility requires the holder to match the insert form, clearance angle, tolerance class, fixation method, size and thickness; the CNMG120408 AH8015 insert fits ISO CNMG seats when these parameters align.

Which workpiece materials suit this grade best?
The AH8015 grade is specified as a first choice for general machining of heat‑resistant alloys; it provides a balance between wear resistance and edge stability for such materials.

Can the insert be used for internal turning?
Yes; the insert is suitable for internal operations when mounted in an appropriate boring bar and clamping system designed for ISO CNMG inserts.

How does the double‑sided design affect cost‑efficiency?
The double‑sided construction allows indexing to a fresh cutting edge, extending service intervals and lowering cost per cutting edge when the insert is used with the correct holder.

What should be considered when choosing the chipbreaker?
Select a chipbreaker that matches the workpiece material, machining type and machine‑workpiece stability; the correct chipformer ensures controlled chips and consistent surface finish.
