CNMG120408 AH6225 ISO turning insert — PVD-coated carbide, 80° rhombic by Tungaloy

CNMG120408 AH6225 is an ISO-compliant indexable insert designed for external and internal turning, optimised for medium machining of stainless steels and varying production conditions

• PVD-coated carbide AH6225 for stainless steels
• ISO CNMG120408 shape for versatile turning
• Double-sided chipbreaker for consistent chips
• 0.8 mm corner radius for controlled cutting

Consistent performance for stainless steels with reduced built-up edge

The CNMG120408 AH6225 insert combines a PVD-coated carbide substrate with a grade tuned to the demands of rostfreie Stähle, providing a sharp yet stable cutting edge for medium-duty turning. The coating reduces adhesion and wear, which helps to limit built-up edge and maintain a consistent surface finish over longer tool life. For production environments with mixed workpiece batches, this delivers predictable cycle times and fewer tool changes.

ISO compatibility and straightforward integration into existing tool systems

As an ISO indexable insert, the CNMG120408 form ensures interchangeability with holders that match the insert’s rhombic 80° geometry, thickness and fastening style. The insert features a 0° clearance angle, a cylindrical hole and a plate thickness of 4.76 mm; these dimensional standards support quick identification of suitable external holders, boring bars and clamp sets. Double-sided indexing extends usable edges per insert, reducing inventory needs and shortening machine downtime during changeovers.

Reliable chip control and stable cutting for repeatable results

The double-sided chipbreaker is designed for stable chip formation in a range of cutting conditions; combined with the corner radius 0.8 mm, it helps to absorb cutting forces and improve edge robustness. This combination supports both finishing and medium roughing when the machining set-up offers sufficient rigidity. The AH6225 grade is balanced for changing conditions, which promotes predictable productivity and consistent component tolerances even when coolant or feed rates vary.

FAQ

Is this insert suitable for stainless steels and what makes it appropriate?
The AH6225 grade of the CNMG120408 insert is tailored for rostfreie Stähle; the PVD coating and the alloy composition reduce adhesion and wear, making the insert suitable for medium-duty stainless steel turning.

Can the CNMG120408 be used in existing ISO holders?
Yes, the ISO CNMG120408 geometry and standard thickness allow use in compatible external holders and boring bars when the holder matches form, tolerance and fastening specifications.

How many cutting edges are available per insert?
The insert is double-sided with indexing on both faces, providing multiple usable cutting edges before replacement is necessary.

What cutting conditions are recommended for the AH6225 grade?
AH6225 is intended for medium machining of stainless steels under varying conditions; select feeds and speeds that suit the machine rigidity and the chosen chipbreaker for optimal life.

Does the insert require a specific chipbreaker choice for different operations?
The double-sided chipbreaker offers good general-purpose chip control; however, selecting the chipbreaker profile and grade according to the workpiece stability and the operation (roughing vs finishing) will yield the best results.
