DNMG150604 AH6225 indexable turning insert (Tungaloy) — PVD-coated carbide, 55° rhombic

A DNMG150604 AH6225 indexable insert for external and internal turning, engineered for consistent performance in stainless steel machining and medium-cutting conditions

• PVD-coated AH6225 for stainless steels
• 55° rhombic shape for versatile turning
• 0.4 mm corner radius for precise finishes
• Double-sided chipbreaker, cylindrical hole

Consistent, adaptable performance in stainless steel turning

The AH6225 cutting grade is a PVD-coated carbide formulated as a universal solution for stainless steels, delivering a balance of a sharp and stable cutting edge suited to medium machining and variable conditions. This combination reduces unexpected tool wear and improves process repeatability, which translates into lower unit costs over production runs. The coating enhances oxidation resistance at elevated temperatures, while the substrate provides toughness against chipping; together they support continuous operation under typical turning feeds and speeds.

Geometry tuned for surface quality and repeatability

The 55° rhombic form and 0° relief angle provide a robust geometry for both external and internal turning, helping to maintain consistent part profiles and reduce vibration. The 0.4 mm corner radius influences both strength at the cutting edge and the achievable surface finish: a modest radius increases edge stability while supporting fine finish capability in interrupted and continuous cuts. As a double-sided indexable insert, the part count per insert is effectively doubled, improving economy without sacrificing dimensional repeatability.

Seamless integration with ISO tooling and reliable chip control

Compatibility with toolholders depends on form, relief angle, tolerance class, fastening, size and thickness; this insert conforms to ISO indexable insert standards to ensure straightforward selection of matching holders and clamping sets. The double-sided chipbreaker and cylindrical hole aid consistent chip formation and secure fastening in the seat, reducing rework due to poor chip evacuation. With a 6.35 mm plate thickness, the insert offers added stability for moderate depths of cut; application-specific cutting parameters and holder selection can be provided on request to optimise cycle times and surface integrity.

FAQ

What materials is this insert designed for?
The DNMG150604 AH6225 insert uses a PVD-coated carbide grade optimised for stainless steels, providing stable cutting performance in medium machining operations.

Which holders and clamps are compatible with this insert?
Compatibility follows ISO indexable insert standards; suitable holders are selected by matching form, relief angle, tolerance class, fastening method, size and thickness to the DNMG150604 AH6225 geometry.

How does the 0.4 mm corner radius affect machining?
A 0.4 mm corner radius increases edge strength and contributes to a consistent surface finish, offering a compromise between robustness and fine finishing capability in typical turning applications.

Is the insert reversible and does it aid economy?
Yes — the insert is double-sided, allowing indexation to a fresh cutting edge and effectively doubling the service life per part compared with single-sided alternatives.
