CNMG120408 AH725 Tungaloy turning insert — ISO CNMG, PVD-coated carbide, 0.8 mm radius

The CNMG120408 AH725 Tungaloy turning insert is an ISO-standard rhombic indexable insert for external and internal turning, engineered for consistent chip control and high process security across varying workpiece materials.

• PVD-coated carbide AH725
• 0.8 mm corner radius, 80° geometry
• Double-sided chipbreaker, rhombic form
• ISO CNMG120408 with cylindrical hole

Stable chip control for reliable production

The AH725 grade features a PVD coating on a carbide substrate to combine wear resistance with toughness, delivering stable chip formation even under mixed cutting conditions. This balance reduces the risk of edge breakout and maintains surface quality, which in turn lowers scrap rates and extends effective tool life. The double-sided chipbreaker is designed to offer repeatable performance on both new and re-indexed edges, so process interruptions are minimised and cycle times remain predictable.

Versatility across materials and turning operations

Selected for universal performance, the AH725 cutting grade is suitable for machining a wide range of materials including steel and stainless steels, making it a sensible choice where workpiece mixes change frequently. The rhombic geometry with an 80° main cutting angle provides the rigidity needed for heavier cuts while the 0.8 mm corner radius helps blend strength with acceptable edge finishing, offering a pragmatic compromise between durability and surface integrity in medium-duty turning.

Engineered for easy integration with ISO tool systems

As an ISO CNMG insert, the component matches common holder families by form, clearance angle, tolerance class, fixing method, size and thickness. The insert’s cylindrical hole supports secure clamping and repeatable seating in the toolholder, reducing set-up time and alignment effort. For workshops seeking quick changeover and consistent results, this indexable insert streamlines tooling logistics and simplifies inventory management.

Productivity and process-security benefits for manufacturers

Using a wear-resistant PVD-coated carbide such as AH725 often translates into longer productive runtimes and fewer tool changes; that means less machine downtime and improved throughput. The insert’s design emphasises process security—a decisive factor in batch production and mixed-series manufacturing where predictable tool behaviour is essential. Choosing this insert supports cost-efficient machining by combining reliable performance with straightforward application in standard turning tasks.
