CNMG 190612 AH120 ISO turning insert, 80° geometry | Tungaloy

A CNMG 190612 AH120 insert designed for reliable external and internal turning, offering a sharp cutting edge and improved process security in ISO‑standard tool systems

• PVD‑coated carbide AH120 for wear resistance
• ISO CNMG rhombic form with 80° cutting edge
• Double‑sided insert with cylindrical hole
• Stable chip control for dependable turning

Consistent edge performance for longer cutting intervals

The PVD‑coated AH120 grade combines a wear‑resistant surface finish with a tough carbide substrate to deliver predictable life and reduced downtime. A sharp cutting edge, backed by a stable microstructure, lowers the frequency of edge failures and preserves surface quality over extended runs. The 1.2 mm corner radius provides a reliable compromise between strength and finish quality, supporting steady tool life when the chipformer is matched to the workpiece and machining parameters. This leads to measurable productivity gains through fewer interruptions for insert changes and less scrap.

ISO conformity and straightforward holder integration

Built to ISO dimensions, the CNMG geometry with an 80° approach angle is compatible with common external holders and boring bars; compatibility depends on form, relief angle, tolerance class, fastening method, size and thickness. The rhombic shape and cylindrical hole enable repeatable seating and clamping, while the 6.35 mm thickness and 19 mm size provide robust support in moderate to heavy turning operations. Because the insert is double‑sided, both faces can be indexed to extend effective life, and the standard interface permits quick replacement without bespoke adaptors, reducing setup time in production cells.

Practical benefits for process security and versatility

Designed for turning tasks where a sharp corner and reliable cutting behaviour are required, this indexable insert supports stable chip formation and consistent surface finish when paired with the appropriate chipbreaker and holder. The CNMG190612 AH120 insert is supplied as part of a standard system consisting of an ISO insert, a matching external holder or boring bar, and the necessary clamping elements; this system approach simplifies inventory and tooling decisions. By selecting the correct chipbreaker profile and maintaining stable cutting conditions, process security is enhanced and the likelihood of unplanned stoppages is reduced.
