CCMT060204 AH6225 Tungaloy turning insert — PVD-coated carbide, 0.4 mm corner radius

The CCMT060204 AH6225 is an ISO rhombic turning insert designed for external and internal turning, optimised for stainless-steel machining.

• PVD-coated carbide grade AH6225
• Optimised for stainless steel machining
• Rhombic ISO insert, 0.4 mm corner radius
• Cylindrical hole with 40°–60° countersink

Consistent cutting performance for stainless steels

The PVD-coated carbide substrate and the AH6225 grade combine to deliver a sharp, stable cutting edge tailored to the demands of rostfrei (stainless) steels. This combination reduces the tendency for built-up edge and improves edge life under the intermittent and adhesive conditions typical for such alloys. In practical terms, the insert sustains reliable cutting forces during medium machining and changing process parameters, which supports predictable cycle times and improved first-pass quality. The PVD layer enhances wear resistance while preserving a keen geometry for improved surface finish.

Simple integration into standard ISO toolholders

Designed as an ISO-conforming rhombic insert, compatibility with a suitable holder depends on form, clearance, tolerance class, fastening method, size and thickness rather than manufacturer alone. The rhombic geometry with a 0.4 mm corner radius and 7° clearance enables repeatable positioning and predictable cutting geometry when used with the correct clamp set and screw. The central cylindrical hole with a single-sided countersink (40°–60°) streamlines secure clamping and axial location, making the insert straightforward to fit into established turning systems while maintaining process stability.

Reliable productivity and economical tool use

The AH6225 grade is formulated for versatile performance on stainless steels, offering balanced wear resistance and edge robustness for medium-cutting conditions. That balance supports longer in-service life and fewer interruptions for insert changes, which improves throughput and overall tool economy. When paired with the one-sided chipbreaker and correct cutting data, the insert helps to manage chip formation and evacuation—key factors in sustaining productivity and surface quality. The stable edge behaviour contributes to reproducible results across batches, reducing scrap and rework costs.

Practical guidance for application and selection

Selection of the correct chipbreaker and matching grade to workpiece stability remain decisive for best results: the one-sided chipbreaker suits many standard turning tasks but should be matched to the work-holding and coolant strategy. For internal turning or constrained setups, attention to holder rigidity and cutting parameters will preserve edge life and surface integrity. When uncertainty arises about matching the insert to a specific workpiece or holder, technical consultation is advisable to align chip control, feed, and speed with the insert’s capabilities.

FAQ

Which materials is this insert best suited for?
The CCMT060204 AH6225 insert is specified as a universal grade for stainless steels, providing a balance of edge strength and wear resistance for typical rostfrei machining tasks.

Can the insert be used for both external and internal turning?
Yes — the geometry and hole design allow use in external and internal turning operations, provided a compatible ISO holder and secure clamping arrangement are employed.

How does the PVD coating affect performance on stainless steel?
The PVD-coated carbide substrate on the CCMT060204 AH6225 improves wear resistance and reduces adhesion, which helps limit built-up edge formation and extends effective tool life under variable cutting conditions.

How is the insert secured in the holder?
Compatibility is governed by the insert form, clearance, tolerance class, fastening, size and thickness; this insert uses a cylindrical hole with a one-sided countersink (40°–60°) for axial location and clamping with the appropriate screw and clamp set.

What effect do the corner radius and clearance angle have on results?
A 0.4 mm corner radius provides a compromise between edge robustness and surface finish quality, while the 7° clearance angle reduces flank contact and helps to maintain a consistent machined profile.
