DCMT070208 AH6225 ISO turning insert — rhombic 07, PVD‑coated carbide by Tungaloy

DCMT070208 AH6225 is an ISO‑standard rhombic turning insert designed for external and internal turning, offering a stable, sharp cutting edge for medium machining of stainless steels.

• PVD-coated carbide for durable edges
• Optimised for stainless steels
• Rhombic ISO 07 shape with 7° relief
• Central hole with single-sided countersink

Consistent, efficient cutting with a universal PVD grade

The AH6225 grade is a PVD‑coated carbide engineered for a balance of edge sharpness and durability under variable conditions. This combination reduces flank wear during medium‑severity operations and supports stable chip formation, which in turn improves process reliability and reduces downtime. The PVD layer enhances resistance to adhesive wear and thermal softening, making the insert suitable where a repeatable surface finish and predictable tool life are priorities.

ISO fit and mechanical compatibility for secure clamping

Designed to the ISO standard, the rhombic ISO 07 form with a 7° relief ensures compatibility with a broad range of external holders and boring bars. The insert is supplied with a central cylindrical hole and a single‑sided countersink (40°–60°) to match common clamp‑and‑screw systems. Holder compatibility is determined by insert form, relief angle, tolerance class, fixation method, size and thickness; the recommended system comprises the insert, a matching outer holder or boring bar, a support pad/clamp set and replacement screws for reliable assembly.

Controlled chips and secure edge for cleaner finishes

A single‑sided chipbreaker and a 0.8 mm corner radius combine to deliver predictable chip control and a robust cutting edge. The chipbreaker is optimised to split and evacuate chips efficiently during turning, reducing entanglement and heat build‑up. The 0.8 mm radius moderates cutting forces, which benefits surface quality and helps maintain dimensional stability when machining parts that require consistent tolerances during medium cutting conditions.

Practical application advice and process considerations

Typical applications include external and internal turning of stainless steels, where a universal grade and a stable edge are required under changing cutting conditions. Selection of the chipbreaker variant and cutting parameters should be matched to material, rigidity of the setup and desired surface finish. If uncertainty exists regarding holder selection or cutting data, Metav Werkzeuge’s technical team can provide guidance on the correct clamp system and cutting parameters to ensure optimal performance.
