CNMG120402 AH6225 ISO turning insert for turning by Tungaloy

The CNMG120402 AH6225 is an ISO-standard rhombic insert for general turning, optimised for machining stainless steels with a sharp yet robust cutting edge suitable for varying conditions.

• PVD-coated carbide grade AH6225
• Rhombic insert, 80° lead angle
• Double-sided chipbreaker for chip control
• 0.2 mm corner radius for balanced finish

Increase throughput with a stable, versatile cutting grade

The AH6225 grade is a PVD-coated carbide developed for predictable performance when turning stainless steels. Its formulation supports a sharp cutting edge that resists wear under medium cutting conditions, which translates into longer effective tool life and fewer interruptions. Improved edge stability means more consistent surface quality and reduced risk of premature edge chipping, so process reliability and productivity rise without complex parameter fine-tuning.

Fast integration thanks to standardised form and clear compatibility data

Compatibility to a toolholder is determined by form, clearance angle, tolerance class, fastening, size and thickness. The rhombic plate with an 80° lead angle and 0° clearance angle fits common ISO holders when those parameters match; the plate sits on a matching pocket and secures via the cylindrical central hole. Clear specification of size (12 mm) and thickness (4.76 mm) makes selection straightforward, reducing setup time and avoiding costly mismatches in production.

Geometry and chip control that balance surface finish and life

A 0.2 mm corner radius provides a balance between edge strength and the ability to achieve a fine finish on the workpiece. The double-sided chipbreaker design helps form short, manageable chips during turning, lowering the risk of entanglement and improving thermal behaviour at the cutting zone. In practice, this means smoother operation on semi-finished components and less need for secondary finishing, while the PVD layer supports wear resistance under fluctuating cutting loads.

Practical guidance for selection and use

When choosing an insert for turning, match the insert geometry and chipbreaker to the workpiece material and machining stability: a sharper geometry suits light, controlled cuts and finishes, while a more robust profile helps with interrupted cuts or less rigid setups. The ISO-standard construction simplifies procurement and inventory management: the same insert family can serve several holders and applications provided the holder’s pocket and fastening match the insert’s form and dimensions.

FAQ

What materials is this insert best suited for?
The CNMG120402 AH6225 insert is designed primarily for stainless steels; the PVD-coated carbide grade AH6225 offers broad applicability across common stainless grades under medium cutting conditions.

How does the chipbreaker influence machining?
The double-sided chipbreaker on this ISO turning insert promotes controlled chip formation and evacuation, reducing re-cutting and improving process stability during turning.

Which holder characteristics must be checked before use?
Verify holder compatibility by checking form, clearance angle (0° for this insert), tolerance class, fastening method, size (12 mm) and plate thickness (4.76 mm) so the CNMG120402 seats and clamps correctly.

Does the insert provide a good surface finish and tool life balance?
Yes; the 0.2 mm corner radius and PVD coating of the AH6225 grade balance edge strength with finish quality, offering a compromise between surface integrity and wear resistance.

Is this an ISO-standard insert and how does that help procurement?
The plate follows ISO specifications, which simplifies selection and stock management when matching pockets and fastening systems across standard turning holders.
