CPMT 09T304 AH725 Wendeplatten - Tungaloy

With a focus on stable chip formation and broad material coverage, the PVD-coated AH725 grade ensures reliable process security and consistent edge life, while the 0.4 mm corner radius and ISO rhombic form deliver repeatable chamfer and profile control in turning operations; order the insert directly via Metav Werkzeuge or consult the technical team for compatibility checks.

CPMT09T304 AH725 Tungaloy turning insert — PVD carbide, rhombic ISO insert for turning

CPMT09T304 AH725 Tungaloy turning insert is an ISO‑standard rhombic insert designed for external and internal turning, offering a robust, universal cutting grade suited to mixed‑material production environments.

• ISO-standard rhombic insert, 80° geometry
• PVD-coated AH725 for process security
• 0.4 mm corner radius for consistent chamfers
• Compatible with cylindrical-hole holders

High process reliability from a universal PVD grade

The PVD-coated AH725 grade has been developed for productive turning across a wide range of Stahl and rostfreier Stahl components. Its combination of fracture-resistant substrate and PVD finish provides stable chip formation and extended edge life, which reduces unexpected tool changes and downtime. The rhombic geometry with an 80° included angle gives robust cutting edges that are particularly effective where interrupted cuts or variable engagement occur, supporting consistent machining results on smaller toolholders and compact setups.

Geometry and mounting that simplify holder selection

The insert's rhombic shape (CPMT form) and the specified 11° clearance angle match common ISO holders; mounting compatibility is determined by form, clearance, tolerance class, fastening and plate thickness. The with‑hole design (cylindrical hole plus one‑sided countersink, 40°–60°) ensures secure clamping in conventional clamping sets and reduces the risk of play during heavy cuts. Where holder choice is uncertain, a check of form and thickness against the holder specification is recommended to confirm correct fit and clamping stability.

Controlled cutting performance and chip control

A one-sided chipbreaker is integrated to promote predictable chip formation under typical turning feeds, improving evacuation and surface quality. The 0.4 mm corner radius supports consistent corner strength and is suitable for chamfering and finishing passes where edge robustness is required. In combination with the AH725 coating, the insert enables a balance of surface finish and productivity, particularly in workshops needing flexible tooling for frequent material changes.

Application overview and practical benefits

Designed for both external and internal turning, this indexable insert is a practical choice for operations demanding high process security and repeatable results. The carbide substrate delivers wear resistance, while the PVD layer improves thermal stability at elevated cutting speeds. For production setups that require adaptability across Stahl and rostfreier Stahl, the insert supports longer tool-life cycles and fewer interruptions, translating into measurable gains in machining throughput and consistency.
