CNMG 120404 AH6225 indexable insert for turning (PVD-coated carbide, 0.4 mm radius) — Tungaloy

A CNMG 120404 AH6225 indexable turning insert designed for medium turning of stainless steels, offering ISO compatibility and a stable cutting edge for varying machining conditions

• PVD-coated cemented carbide grade AH6225
• Optimised for stainless steel turning
• Rhombic CNMG profile with 0.4 mm radius
• Double-sided insert with cylindrical hole

Consistent cutting performance for medium turning

The PVD-coated cemented carbide composition ensures a reliable balance between edge sharpness and wear resistance under typical medium-turning parameters. The AH6225 grade is formulated as a universal option for stainless steels, delivering a predictable tool life across changing batch conditions. This combination reduces the need for frequent tool changes and supports steady production rhythms, which helps to improve process predictability and reduce overall machining costs.

Secure mounting and ISO-compatible geometry

The rhombic CNMG profile follows ISO standards and is supplied with a cylindrical hole, enabling safe clamping in compatible holders and boring bars. The insert’s 4.76 mm thickness and defined form ensure repeatable positioning in the toolholder; the 0° clearance angle and 80° included angle are engineered to match established holder geometries. These mechanical attributes simplify integration into existing setups and lower the effort required for fixture validation, providing clear benefits for shop-floor engineers and production planners.

Chip control and edge stability for reliable process outcomes

A double-sided chipbreaker and the 0.4 mm corner radius offer a compromise between surface finish and edge robustness. The chipbreaker geometry promotes controlled chip formation, reducing the risk of entanglement and improving evacuation when turning long or difficult-to-manage components in stainless steels. The PVD layer enhances edge stability against built-up edge formation under fluctuating temperatures, supporting a consistent surface quality and fewer rework cycles.

Practical advantages for workshop efficiency

Selecting a universal grade such as AH6225 simplifies tool inventory and eases tooling decisions across varied workpiece batches. The insert’s universal nature reduces setup complexity and shortens downtime for retooling. Where higher cutting speeds or specific materials demand it, the clear labelling and ISO designation make substitution and sorting straightforward, helping maintenance teams to keep machines productive and predictable.
