CPMT 090304 AH725 indexable turning insert — PVD‑coated carbide, 0.4 mm radius (Tungaloy)

The CPMT 090304 AH725 is an ISO‑standard indexable insert engineered for external and internal turning operations, offering a universal, fracture‑resistant grade suitable for mixed‑material production where process stability is prioritised.

• ISO‑standard CPMT geometry
• PVD‑coated AH725 carbide grade
• 0.4 mm corner radius for fine profiles
• 11° clearance angle for secure cutting
• Rhombic 09 form with central hole

Consistent performance for mixed‑material turning

The PVD‑coated carbide AH725 provides a balance between toughness and wear resistance that is beneficial when machining both steel and rostfreier Stahl. The coating enhances surface hardness and reduces adhesion, which translates into longer edge life and fewer unexpected tool changes. For shops processing batches with varying workpiece materials, this grade reduces the need for frequent insert swaps, supporting a more continuous production flow and predictable cycle times. The combination of substrate and coating is explained here so that non‑specialists understand: PVD (Physical Vapour Deposition) forms a thin, wear‑resistant layer on the carbide that limits flank wear and helps maintain dimensional accuracy over multiple parts.

Fast indexability and secure clamping for uptime gains

Designed to ISO dimensions, the insert matches standard CPMT holders and clamping systems when form, relief angle, tolerance class, fixing method, size and thickness align. The 0.4 mm corner radius and 11° clearance angle are optimised for medium‑finishing passes, producing a reliable surface finish while limiting cutting forces. The central hole with a cylindrical seat and one‑sided countersink (40°–60°) ensures repeatable seating and fast index changes, which reduces machine downtime. Compatibility with standard toolholders also simplifies tool management and inventory, helping maintenance and production planners keep tool cupboards lean.

Improved chip control and process security during turning

The insert’s single‑sided chipbreaker is tuned for controlled chip formation in turning tasks, supporting continuous chips on long parts and predictable breakage in interrupted cuts. Controlled chip flow lowers the risk of rework and tool interference, especially when working with long or thin components. The AH725 grade is pitched as a universal, anti‑chip‑break grade that emphasises process security, making it especially useful in batch production or mixed‑material runs where consistent performance is critical rather than maximising single‑cut metal removal rates.

FAQ

What materials is this insert suited for?
The CPMT 090304 AH725 insert is designed mainly for steel and rostfreier Stahl applications; the AH725 grade provides universal, fracture‑resistant performance for mixed material runs.

How does the AH725 grade affect tool life?
AH725’s PVD coating and carbide substrate combine to reduce flank wear and improve edge stability, extending the effective life of the CPMT 090304 insert under typical turning conditions.

Which holders are compatible with this ISO insert?
Compatibility depends on matching the ISO CPMT form, relief/freiwinkel (11°), tolerance class, fixing method, size (09) and plate thickness (3.18 mm); the insert fits standard CPMT holders that meet these parameters.

What chip control can be expected from the single‑sided chipbreaker?
The single‑sided chipbreaker on this insert promotes controlled chip formation for turning, improving process security and reducing the likelihood of problematic chip behaviour on long parts.

Is this insert suitable for internal as well as external turning?
Yes, the CPMT 090304 AH725 is specified for both external and internal turning tasks when the holder and machining setup are appropriate.
