TNMG 160404 AH6225 Tungaloy turning insert for turning

TNMG160404 AH6225 Tungaloy is an ISO-indexed triangular turning insert designed for external and internal turning of stainless steels, offering reliable edge stability in medium machining and variable conditions.

• ISO triangular TNMG insert, 60° geometry
• PVD-coated carbide grade AH6225 for stainless steel
• 0.4 mm corner radius for consistent edge strength
• Double-sided chipbreaker, central cylindrical hole

Consistent cutting performance for stainless-steel turning

The combination of a PVD-coated carbide substrate and the AH6225 grade provides a balance between a sharp cutting edge and lasting wear resistance during medium-duty operations. The coating reduces built-up edge and improves heat resistance, which results in longer edge life and steadier machining when working with austenitic and other stainless steels. By selecting a universal grade tuned for variable conditions, material-specific chatter and surface deviations are minimised, supporting consistent component quality across batch runs while lowering the need for frequent insert changes.

Geometry and design that support precision and repeatability

The triangular, 60° geometry with a 0.4 mm corner radius gives a predictable cutting profile and repeatable corner strength for turned features. The insert is double-sided with a central cylindrical hole for secure clamping; this enables two usable edges per index and straightforward replacement without complex setup. A plate thickness of 4.76 mm and ISO-standard dimensions ensure compatibility with standard holders, while the 0° clearance angle and standard size designation provide consistent contact conditions and reliable clamping stiffness, which together reduce vibration and improve surface finish.

System integration and economical operation

Built as part of an ISO insert system, the plate fits with matching external holders, shims and clamping kits to create a complete tooling solution. The double-sided chipbreaker geometry contributes to predictable chip control and can extend productive cutting windows, reducing tool change frequency and downtime. For operations seeking to combine process reliability with cost awareness, the universal AH6225 grade delivers a pragmatic compromise between performance and economy, especially where varied stainless-steel alloys and intermittent cutting conditions occur.
