CPMT 080204 AH725 — Turning insert, PVD-coated carbide, 0.4 mm radius (Tungaloy)

The CPMT080204 AH725 is an ISO‑standard rhombic turning insert designed for external and internal turning; its fracture‑resistant PVD carbide grade suits mixed production and small‑tool applications.

• PVD-coated carbide AH725 for versatile performance
• Fracture-resistant grade for high process security
• Rhombic ISO plate, 08 size, 11° relief angle
• Cylindrical hole with 40°–60° countersink

Consistent cutting performance for secure production

The PVD‑coated carbide grade AH725 combines a wear‑resistant surface with a tough substrate, which translates directly into improved tool life and fewer unplanned changes. For turning of steel and stainless steels the coating reduces abrasive wear while the base carbide absorbs cutting loads, so cycle times remain stable. The universal character of the grade makes it suitable where workpiece materials change frequently, offering a clear cost‑benefit through reduced tool inventory and predictable process behaviour.

Geometry and chip control that reduce rework

A rhombic plate form together with a single‑sided chipbreaker creates effective chip control for both roughing and light finishing passes. The small 0.4 mm corner radius supports fine surface quality on finishing cuts, while the 11° relief angle reduces flank contact and heat build‑up. The plate’s cylindrical hole with 40°–60° countersink ensures positive seating and repeatable clamping, which is essential for dimensional consistency in production batches and for minimising vibration in smaller toolholders.

ISO compatibility and integration into existing tool systems

As an ISO‑indexable insert, the plate fits a broad range of external holders when matched for form, relief, tolerance class, fastening and thickness. The 2.38 mm thickness and 08 size permit use in compact toolholders where space and stability are critical. Specifying the correct chipbreaker and grade for the application simplifies process planning: the combination of AH725 and the right geometry delivers high process security and reliable surface finish with reduced set‑up risk, beneficial for mixed‑material production and jobs with strict repeatability requirements.
