CNMG 120402 AH8015 indexable insert for turning — Tungaloy

The CNMG120402 AH8015 is an ISO-standard indexable insert engineered for external and internal turning of heat-resistant alloys, offering a balanced mix of wear resistance and edge stability.

• ISO-standard CNMG geometry
• PVD-coated AH8015 carbide grade
• Double-sided chipbreaker
• 0.2 mm corner radius, 80° rhombic form

Reliable performance for heat-resistant alloys

The CNMG120402 grade combines a PVD-coated AH8015 substrate with a geometry optimised for heat-resistant alloys. This composition achieves a compromise between wear resistance and cutting-edge stability, which reduces flank wear under thermal stress and extends productive cutting time. For general-purpose turning of high-temperature alloys, the carbide grade provides predictable abrasion behaviour and helps to maintain dimensional accuracy over longer tool life. Choosing this grade supports repeatable process windows in batch and single-part production.

Consistent chip control and improved surface quality

The rhombic 80° form and double-sided chipbreaker design promote controlled chip formation and evacuation during interrupted or continuous cuts. With a 0.2 mm corner radius, the insert offers a robust edge for stable engagement while supporting acceptable surface finish on turned components. The 0° clearance angle influences toolwork contact and should be considered when pairing the insert with a toolholder to achieve the desired cutting geometry. Together, these features translate into fewer machining interruptions, better surface integrity and a lower cost per component in longer production runs.

ISO compatibility and practical mounting guidance

As an ISO-standard CNMG120402 insert, compatibility with the chosen holder depends on matching the insert form, clearance angle, tolerance class, fixing method, size and thickness. The typical system comprises the indexable insert, a matching external holder or boring bar, a support/locking kit and replacement screws. Select the chipbreaker and grade according to the workpiece material, machining type and required stability; this ensures consistent performance when the insert is integrated into existing tool systems. The balanced specification of this insert simplifies inventory management and replacement planning in workshop environments.
