CCMT 09T304 AH6225 Wendeplatten - Tungaloy

Take advantage of the combination of PVD-coated carbide, an 80° rhombic geometry and a 0.4 mm nose radius to achieve stable edge life and reliable finishing on stainless steels; order the insert directly via Metav Werkzeuge or ask the consultants for application support.

CCMT09T304 AH6225 Tungaloy Turning Insert — PVD-coated carbide, 0.4 mm radius

The CCMT09T304 AH6225 is an ISO rhombic turning insert designed for medium machining operations and optimised for stainless steel turning applications.

• PVD-coated carbide for robust edge life
• Designed for stainless steel applications
• 0.4 mm nose radius for precise profiles
• ISO rhombic insert with 80° geometry

Consistent machining performance for stainless steel turning

The PVD-coated carbide grade AH6225 is formulated for a wide range of tasks on stainless steel, delivering a balance between a sharp cutting edge and edge stability under variable conditions. The coating reduces flank adhesion and improves wear resistance, so surface finish and tool life are both enhanced. For shops seeking predictable productivity, the coating and substrate combination ensures that the cutting edge is maintained across interrupted cuts and mixed feed rates. In practical terms, this means fewer insert changes and steadier part quality over long runs.

Precise form control and chip management for reliable cycles

The rhombic 80° geometry and 0.4 mm nose radius provide accurate profile definition and low cutting forces during finishing passes. A one-sided chipbreaker is integrated on the insert to assist controlled chip formation; this reduces the risk of tangling and improves evacuation in both external and internal turning. The insert is ISO-compatible, so holders are selected on the basis of ISO form, clearance angle, tolerance class, fastening method, size and thickness to guarantee correct seating and clamping. For engineers less familiar with indexable tooling, the term “chipbreaker” refers to a machined feature that breaks chips into manageable lengths, improving surface quality and machine uptime.

Workshop handling and application guidance for efficient use

The plate is manufactured in a rhombic form with a central hole and a single-sided countersink (40°–60°) that matches conventional clamping systems; plate thickness is 3.97 mm and nominal size is 09 (index 09). Because the insert is supplied to ISO standards, compatibility is determined by geometric match rather than brand alone, simplifying stocking and toolholder selection. The insert’s nominal clearance angle of 7° and its 80° main cutting angle are devised to support versatile turning operations, from external profiling to certain internal cuts when the holder allows. For best results, select feeds and speeds according to the workpiece batch size and rigidity of the setup, favouring moderate parameters for mixed or difficult-to-machine stainless steels.

FAQ

Is this insert suitable for machining stainless steel?
Yes. The CCMT09T304 AH6225 Tungaloy insert is a universal grade formulated for stainless steel and is optimised to combine a sharp cutting edge with edge stability under varying conditions.

What holder characteristics are required for correct seating?
Compatibility is based on ISO form, clearance angle, tolerance class, fastening method, size and thickness; the rhombic form and central hole with countersink match standard ISO-compatible clamping systems.

How does the 0.4 mm radius influence part finish?
A 0.4 mm nose radius provides fine profile control and improved surface finish at finishing feeds; it also spreads cutting forces to enhance edge life compared with very small radii.

Does the insert include a chipbreaker and how does it perform?
Yes. The plate features a one-sided chipbreaker designed to produce shorter chips for safer evacuation and more consistent surface quality during turning operations.

Can this insert be used for internal turning?
Internal use is possible when combined with a suitable boring bar or holder that accommodates the 80° rhombic geometry and provides sufficient rigidity for the intended operation.
