DNMG150608 AH6225 Tungaloy indexable insert for turning (PVD-coated carbide, 55°)

The DNMG150608 AH6225 is an ISO rhombic indexable insert engineered for external and internal turning, providing a sharp yet stable cutting edge suited to medium machining of stainless steels.

• PVD-coated cemented carbide AH6225
• Sharp, stable cutting edge for medium turning
• ISO rhombic DNMG 55° geometry, hole style cylindrical
• Double-sided chipbreaker for versatile chip control

Reliable edge life and consistent chip control

The combination of a PVD-coated AH6225 grade and a robust carbide substrate delivers a balance between sharpness and durability. This results in a cutting edge that resists premature wear while maintaining a clean cutting action, reducing the need for frequent index changes. The integrated chip control geometry – a double-sided chipbreaker – guides chips reliably away from the workpiece, which lowers the risk of rework and improves cycle stability during batches of medium-demand turning tasks.

Versatile geometry for external and internal turning

The rhombic DNMG form at a 55° lead angle enables flexible application across both external and internal turning operations. As an indexable insert, compatibility with the toolholder is governed by form, clearance, tolerance class, fastening method, size and thickness; the ISO standardisation ensures straightforward replacement and interchangeability. The insert’s cylindrical hole provides secure locating in holders and facilitates repeatable positioning for high-volume machining routines.

Predictable surface quality when machining stainless steels

Designed as a universal grade for stainless steels, the AH6225 composition supports variable cutting conditions without sacrificing finish quality. The relatively sharp cutting edge minimises built-up edge and helps achieve consistent surface roughness during medium machining passes, which reduces downstream finishing effort. With fewer interruptions for edge changes, the grade contributes to improved productivity and a more favourable cost-in-use ratio for stainless-steel components.

Simplified handling and ISO-compliant system integration

The insert’s 6.35 mm plate thickness and standardised ISO designation streamline inventory and toolset selection. The ISO conformity of the DNMG form aids rapid identification of compatible holders, shims and clamping kits, reducing setup time. The cylindrical hole and the toleranced geometry ensure positive location and repeatable clamping, while the durable carbide body maintains dimensional stability over multiple indexings, supporting efficient tool management in production environments.
