DCMT 11T304 AH6225 — Tungaloy indexable insert for turning, PVD-coated carbide, 55° geometry

DCMT11T304 AH6225 is an ISO-standardised rhombic indexable insert designed for precision external and internal turning in industrial machining environments

• Universal AH6225 grade for stainless steel
• PVD-coated carbide for improved wear resistance
• 55° rhombic geometry with 7° clearance
• 0.4 mm corner radius for versatile profiles

Consistent compatibility and quick set-up for ISO turning systems

The ISO indexable insert design ensures predictable fitment across standard turning holders: compatibility depends on insert shape, clearance angle, tolerance class, fixing method, size and thickness. The ISO format reduces setup time and inventory complexity, enabling fast replacement and repeatable positioning. With a 55° lead angle and a 3.97 mm thickness, the insert provides a stable connection to matched holders and boring bars. This standardisation translates into measurable productivity gains through reduced downtime and simplified tool management.

Reliable cutting performance in variable stainless steel conditions

The AH6225 designation denotes a PVD-coated carbide grade optimised for machining stainless steel under changing conditions. The specification aims to combine a relatively sharp cutting edge with edge stability to resist built-up edge and premature wear. The single-sided chipbreaker geometry promotes controlled chip formation, improving surface finish and reducing secondary operations. As a result, users benefit from longer in-process life, fewer interruptions for index changes and more consistent part quality when facing mixed batches or intermittent cutting parameters.

Practical application guidance for economical turning operations

Designed for both external and internal turning, the insert forms part of a system comprising an ISO insert, the appropriate external holder or boring bar, a support/locking set and replacement screws. The rhombic shape with a 0.4 mm corner radius suits profile versatility while the cylindrical hole with single-side countersink (40°–60°) secures repeatable clamping. The 7° clearance angle helps prevent rubbing on the workpiece, particularly when working with slender setups. Selecting the correct chipbreaker and grade according to material, operation and machine stability will deliver the intended balance of edge life and surface quality.
