CNMG 190612 AH8015 Tungaloy turning insert — ISO rhombic indexable insert for turning

The CNMG 190612 AH8015 is an ISO rhombic indexable insert engineered for external and internal turning, offering a combination of wear resistance and cutting‑edge stability suitable for heat‑resistant alloy machining.

• ISO rhombic CNMG 80° geometry
• PVD-coated carbide grade AH8015
• 1.2 mm corner radius for stability
• Double-sided chipbreaker, with cylindrical hole

Reliable performance with PVD-coated carbide for heat-resistant alloys

The combination of a PVD-coated carbide substrate and the AH8015 grade gives a measured compromise between wear resistance and edge security, making this insert a reliable choice for machining temperature‑resistant alloys. In practical terms, the coating reduces flank and crater wear under elevated cutting temperatures, while the substrate maintains fracture resistance. This results in extended service intervals and more predictable tool life, which supports continuous production runs and lowers unexpected stoppages.

Stable geometry and secure clamping for repeatable turning results

The 80° rhombic geometry and 1.2 mm corner radius deliver mechanical stability at the cutting edge, enabling secure engagement in both external and internal turning operations. The double‑sided chipbreaker provides two indexing positions, improving cost efficiency per insert, while the cylindrical hole ensures positive clamping and consistent seating in compatible holders. The 6.35 mm plate thickness supports robust clamping forces and helps absorb cutting loads, contributing to consistent surface finish and reduced vibration.

System compatibility and straightforward selection for production environments

This insert is part of the ISO series of indexable turning plates and is compatible with holders where form, clearance angle, tolerance class, fastening, size and thickness match. Selecting the appropriate chipbreaker and grade according to workpiece material and process stability is essential: the AH8015 grade is the preferred option for general machining of heat‑resistant alloys, while different chipformers optimise swarf control and surface quality. Clear specifications reduce setup time and increase process security on production‑grade lathes.

Practical application advice for efficient machining

Designed for both external and internal turning, the CNMG series insert supports productive machining strategies when paired with a suitably rigid toolholder and stable clamping. The balanced material properties of the grade make the insert suitable for continuous and interrupted cuts where a compromise between edge life and toughness is required. For best results, combine the insert’s geometry with appropriate cutting parameters and cooling strategy to achieve repeatable surface integrity and predictable wear.
