CNMG120408 AH8015 Tungaloy indexable insert for turning — PVD‑coated carbide, 80° rhombic

CNMG120408 AH8015 Tungaloy indexable insert offers ISO‑standard compatibility for general turning applications and is optimised for heat‑resistant alloys

• ISO‑standard CNMG insert, 80° rhombic
• PVD‑coated carbide AH8015 for high temperatures
• Double‑sided chipbreaker for consistent chips
• Cylindrical hole fixation, suitable for common holders

Consistent machining of heat‑resistant alloys with fewer tool changes

The PVD‑coated carbide grade AH8015 is formulated as a first choice for the general machining of heat‑resistant alloys, offering a compromise between wear resistance and cutting‑edge stability. This balance reduces unexpected edge failures and extends intervals between tool changes, which in turn supports predictable cycle times on turning machines. The coating contributes to thermal protection at the cutting edge, helping to maintain dimensional stability on long runs without sacrificing surface finish.

Fast installation and reliable holder compatibility reduce setup time

Compatibility with the toolholder depends on form, relief angle, tolerance class, fastening and the insert’s size and thickness; the ISO‑standard rhombic shape and the cylindrical hole ensure straightforward seating in common external holders or boring bars. The nominal 0° clearance and the standardised 80° geometry make this insert readily interchangeable within ISO systems, simplifying tooling logistics and reducing downtime for changeovers. Clear specification of form and thickness helps engineering teams select the correct clamping and backup items for robust assembly.

Improved chip control and stable cutting for higher productivity

The double‑sided chipbreaker design creates repeatable chip forms across a range of cutting conditions, which supports consistent evacuation and reduces the risk of chip entanglement. Stable chip formation, combined with the carbide substrate and PVD surface, means fewer interruptions for chip clearing and improved process security on automated lathes. For operations where surface integrity matters, the insert delivers a balance of surface quality and tool life that contributes directly to overall equipment effectiveness.

System considerations and application guidance

The insert is intended for external and internal turning; selection of the precise chipbreaker and grade should match the workpiece material, machining method and machine‑tool stability. The ISO series structure implies a system build consisting of the indexable insert, a compatible external holder or boring bar, and the appropriate clamp/seat and replacement fixing screws. For applications that demand repeatable tolerances and predictable tool life, the combination of AH8015 coating and standard geometry supports both batch production and flexible jobbing environments.
