YNMG 160408 AH6225 — ISO turning insert, PVD-coated carbide by Tungaloy

A YNMG160408-ZM AH6225 insert engineered for external and internal turning, offering a sharp yet stable cutting edge for rostfreier Stahl and mixed machining conditions

• PVD-coated cemented carbide AH6225
• Optimised ZM chipbreaker for rostfreier Stahl
• 0° clearance and 0.8 mm corner radius
• ISO 160408 form with cylindrical hole

High-performance grade for consistent stainless-steel turning

The AH6225 grade is a PVD-coated cemented carbide developed for universal use on rostfreier Stahl, balancing a sharp cutting edge with long-term edge stability. In mid-range turning and variable machining conditions the coating reduces built-up edge and friction, which leads to more consistent surface finishes and extended insert life. The result is repeatable process windows and fewer unscheduled tool changes, translating into measurable productivity gains on turning lines.

Geometry and chip control that stabilise the cut

The ZM chipbreaker offers controlled chip formation for external and internal turning, especially where chip evacuation is critical. Combined with the 0° clearance geometry and a 0.8 mm corner radius, the insert delivers reliable edge engagement and dimensional stability on interrupted or stable cuts. Compatibility with a holder is determined by insert form, clearance angle, tolerance class, clamping method, size and thickness, so selecting matching clamping sets ensures secure mounting and repeatable cutting behaviour.

ISO system advantages and economical process design

As an ISO-normed turning insert, the component integrates into standard systems comprising an outer holder or boring bar, a shim/clamp set and replacement screws. This modular approach simplifies inventory management, shortens changeover times and lowers overall process costs. The standardised format also allows straightforward comparison between grades and geometries, enabling process engineers to optimise feeds and speeds with predictable tool life and surface quality outcomes.

Application guidance and practical service options

For workshop planners and process engineers seeking tailored set-ups, technical data and holder recommendations are available to support correct component pairing. Metav Werkzeuge offers application advice to match insert geometry, chipbreaker and grade to specific turning tasks without unnecessary experimentation. The combination of a robust carbide substrate and a PVD surface treatment ensures dependable performance across a broad range of rostfreier Stahl alloys while maintaining good tool life and stable chip formation.

FAQ

What materials is this insert suited for?
The AH6225 grade is specified for machining rostfreier Stahl and covers a wide range of stainless alloys in medium turning operations.

How does the ZM chipbreaker affect machining?
The ZM chipbreaker on the insert promotes controlled chip formation and evacuation, improving surface finish and reducing the risk of entangling chips during turning.

What does the ISO 160408 designation mean for compatibility?
ISO 160408 defines the plate geometry and dimensions; the insert fits holders and clamping systems designed for that ISO format when form, thickness and clamping match.

Can the insert be used for internal as well as external turning?
Yes, the combination of geometry and chip control is suitable for both external and internal turning applications when paired with the correct boring bar or holder.

Is the 0.8 mm corner radius suitable for finishing passes?
A 0.8 mm radius provides a compromise between edge strength and finish capability; it is effective for semi-finishing and medium finishing tasks.

How is repeatability ensured when replacing inserts?
The ISO-normed format and controlled tolerance classes ensure repeatable seating and clamping, maintaining consistent cutting geometry across insert changes.
