DCMT070208 AH725 — ISO rhombic turning insert, PVD‑coated carbide by Tungaloy

The DCMT070208 AH725 is an ISO‑standard rhombic indexable insert for external and internal turning, engineered for stable chip formation and consistent performance when machining steels and stainless steels.

• ISO rhombic insert DCMT070208
• PVD‑coated carbide AH725 for steels
• 55° geometry with 0.8 mm radius
• Cylindrical hole + single-side countersink

Consistent cutting performance for industrial turning

The PVD‑coated carbide construction delivers a balanced combination of wear resistance and edge stability, making the insert suited to continuous production and batch work. The AH725 grade provides a universal, fracture‑resistant substrate optimised for a broad range of steels and stainless steels, reducing the risk of unexpected edge failure in mixed‑material shops. The 55° rhombic geometry and 0.8 mm corner radius produce repeatable cutting lines and enable conservative approaches to finish turning; this translates to reliable part tolerances and fewer rejected components in serial production.

Compatibility and assembly that save set‑up time

Designed as an ISO indexable insert, the part matches standard holders when the form, free angle, tolerance class, fixing method, size and thickness align. The 7° clearance minimises flank rubbing, while the cylindrical hole with single‑side countersink (40°–60°) ensures firm clamping and quick replacement during changeovers. The insert integrates smoothly into a system comprising an appropriate external holder or boring bar, a backing pad or clamp set, and replacement screws, supporting fast tool changes and predictable cycle times on CNC lathes.

Process security and material versatility

With a one‑sided chipbreaker and the AH725 coating concept, this insert emphasises process security for variable jobs and smaller toolholders. The combination of geometry and coating improves chip control and surface finish in operations where rigidity varies or where multiple steel grades are encountered. For shops seeking a single, dependable insert for finishing and light to medium roughing, the technical balance of substrate and coating reduces tool inventory complexity while maintaining productivity.
