CPMT 09T302 AH6225 Tungaloy Turning Insert — PVD‑coated carbide, 80° rhombic for turning

A CPMT09T302 AH6225 ISO turning insert engineered for external and internal turning of stainless steels, offering a sharp yet stable cutting edge for mid‑range machining.

• PVD-coated carbide AH6225 grade
• Optimised for stainless steels
• Rhombic 80° geometry
• 0.2 mm corner radius
• Cylindrical hole with countersink 40°–60°

Consistent cutting performance under changing conditions

The PVD‑coated AH6225 grade combines a hard coating with a wear‑resistant carbide substrate to deliver extended tool life and repeatable results. Designed as a universal grade for stainless steels, the geometry supports a sharp cutting edge without sacrificing edge stability, which reduces the tendency for built‑up edge and improves process security. This balance makes the insert suitable for varied batch sizes and mixed production runs where tool reliability matters most.

Secure clamping and straightforward ISO compatibility

Compatibility with tool holders is defined by form, relief angle, tolerance class, fastening method, size and thickness; the insert conforms to ISO standards to ease holder selection. The central cylindrical hole with a one‑sided countersink (40°–60°) ensures secure clamping and correct seating in matched carriers, while the relief angle of 11° contributes to consistent cutting action. With a plate thickness of 3.97 mm, the insert integrates into common cutting systems for straightforward assembly and reliable repeatability.

Geometry tuned for surface quality and predictable forces

The rhombic shape at 80° and a 0.2 mm corner radius deliver a balance between form strength and finishing capability. A small radius reduces cutting forces for finer surface finishes, while the robust geometry resists chipping during interrupted cuts or variable cutting conditions. Understanding how corner radius affects cutting load allows process planners to optimise feeds and depths of cut for required surface tolerance without unnecessary trial and error.

System readiness and recommended turning applications

The insert is part of a system comprising an ISO turning insert, a compatible external holder or boring bar, underlay/clamp set and replacement screws. The single‑side chipbreaker is intended to support chip control in typical turning operations; choose chipbreaker and approach depending on workpiece stability and machining strategy. This CPMT09T302 AH6225 insert is primarily for turning—external and internal—where a combination of a sharp cutting edge and edge robustness is required for productive machining of stainless steels.

FAQ

Is this insert suitable for stainless steels?
Yes. The CPMT09T302 AH6225 insert is formulated as a universal grade for stainless steels, offering a sharp, stable edge for mid‑range machining.

Which holders are compatible with this ISO insert?
Compatibility depends on the holder’s form, relief angle, tolerance class, fastening method, size and thickness; use holders designed for ISO rhombic 80° inserts to fit this CPMT09T302 insert.

What does the 0.2 mm corner radius mean for surface finish?
A 0.2 mm corner radius reduces cutting forces compared with larger radii, aiding improved surface finish while maintaining sufficient edge strength for typical turning tasks.

How does the hole and countersink affect clamping?
The cylindrical hole with a one‑sided countersink (40°–60°) ensures secure seating and stable clamping in matched tool carriers, which improves repeatability and reduces vibration.

For which operations is the one‑sided chipbreaker intended?
The one‑sided chipbreaker is intended for general external and internal turning where chip control and predictable chip formation are required under varying cutting conditions.
