DPMT11T304 AH6225 Turning Insert — ISO Rhombic, 11° Clearance (Tungaloy)

The DPMT11T304 AH6225 is an ISO rhombic turning insert for external and internal turning, engineered for reliable stainless‑steel machining in a wide range of workshop and production environments.

• PVD-coated carbide AH6225
• Optimised for stainless steel machining
• Rhombic ISO insert with 11° clearance
• 0.4 mm corner radius and one-sided chipbreaker

Consistent performance through a balanced grade and coating

The PVD-coated AH6225 grade combines a wear‑resistant coating with a substrate optimised for edge stability, providing a balance between sharpness and robustness suitable for stainless steel. This configuration reduces flank wear and helps maintain a stable cutting edge under intermittent conditions, which means fewer insert changes and more predictable component quality. The deposit architecture of a PVD finish improves resistance to built‑up edge and abrasion, so the machining process stays productive even when conditions vary.

Geometry that reduces rework and improves process security

The rhombic geometry and 11° clearance result in a versatile insert geometry that supports both external and internal turning operations while controlling cutting forces. The 0.4 mm corner radius smooths contact with the workpiece to enhance surface finish without sacrificing rigidity, and the cylindrical hole with single‑side countersink (40°–60°) ensures secure clamping in ISO holders. Because compatibility depends on form, clearance, tolerance class, fastening, size and thickness, the insert integrates seamlessly into standard tool systems when the correct clamping and shim set are used, enabling consistent, repeatable setups.

Productivity gains from targeted chip control and system design

A one‑sided chipbreaker designed for medium cutting conditions delivers effective chip formation and evacuation during turning, reducing the risk of chip packing and enhancing cycle stability. The 3.97 mm plate thickness contributes to mechanical stiffness, helping to dampen vibrations in less rigid setups. Together with the grade characteristics, these features support higher process security and can shorten machining cycles by maintaining cutting performance over longer tool life. For best results, pair the insert with a holder and machining parameters matched to workpiece rigidity and surface finish targets.
