CCMT 09T304 AH725 – Tungaloy indexable turning insert for turning

The CCMT09T304 AH725 is an ISO‑designation rhombic indexable insert engineered for external and internal turning, providing universal, fracture‑resistant performance on Stahl and rostfreier Stahl.

• Universal PVD-coated grade AH725
• Rhombic 80° geometry for stable cutting
• 0.4 mm nose radius for controlled profiling
• Cylindrical hole with one-sided countersink (40°–60°)

High process security through advanced coating and substrate

The insert combines a PVD coating with a tough carbide substrate to balance wear resistance and edge robustness. The AH725 grade is specified as a universal, fracture‑resistant sort, making it suitable when varying workpiece materials or smaller tool sizes demand consistent performance. The coating reduces adhesion and thermal wear while the substrate absorbs intermittent loads, which in practice means longer periods between index changes and fewer unplanned stoppages, improving overall machining uptime.

Geometry engineered for repeatable precision and secure clamping

A rhombic plate with an 80° approach angle and 0.4 mm corner radius delivers a robust edge for both roughing and fine finishing. The 7° clearance angle preserves edge life by reducing rubbing, and the plate thickness of 3.97 mm contributes to stiffness when mounted. The combination of a cylindrical hole and a one‑sided countersink (40°–60°) ensures positive seating and consistent clamping torque, so toolholders register the insert reliably and maintain concentricity during higher feeds and interrupted cuts.

Practical selection advice to boost productivity on the shop floor

Compatibility with ISO holders is determined by plate form, clearance angle, tolerance class, fixing and thickness; choosing the matching holder and torque setting prevents seating errors. The single‑sided chipbreaker is tuned for predictable chip control in a wide range of turning operations, which supports stable cutting and easier chip evacuation. For process planning, pair this grade with feeds and speeds adjusted to material class (Stahl or rostfreier Stahl) to benefit from the insert’s balance of wear resistance and edge security.

FAQ

Which materials is this insert suitable for?
The CCMT09T304 AH725 insert is designed as a universal, fracture-resistant grade for machining Stahl and rostfreier Stahl, offering reliable wear behaviour across common turning applications.

What does the 80° rhombic geometry mean for cutting performance?
An 80° rhombic geometry provides a strong cutting edge and even load distribution; this geometry, combined with the 0.4 mm radius and 7° clearance, supports consistent surface finish and longer edge life during varied turning tasks.

How is the insert fixed and what ensures secure clamping?
The plate features a cylindrical hole with a one-sided countersink (40°–60°), which together with the correct holder and torque specification ensures firm seating and repeatable clamping for the indexable system.

Can this insert be used for internal turning operations?
Yes, the rhombic form and the single-sided chipbreaker make the insert suitable for both external and internal turning; selection of the correct chipbreaker and holder geometry is advised for optimal chip control.
