CNMG090412 AH6225 indexable insert — PVD-coated carbide, 80° rhombic geometry (Tungaloy)

The CNMG090412 AH6225 indexable turning insert is designed for external and internal turning, optimised for machining stainless steels with a sharp yet robust cutting edge.

• PVD-coated carbide grade AH6225
• 80° rhombic CNMG geometry
• 1.2 mm corner radius for reliable edge
• Cylindrical hole, double-sided chipbreaker

Stable cutting performance for stainless steels

The combination of the AH6225 PVD coating and a carbide substrate provides a balance between sharpness and toughness that suits intermittent and continuous cuts in stainless steels. The coated surface improves wear resistance and reduces adhesive built-up on the edge, while the grade’s formulation supports a stable cutting edge under changing conditions. This results in more consistent tool life and predictable machining outcomes in series production.

Geometry tuned for predictable chip control and rigidity

The 80° rhombic CNMG shape and the 1.2 mm corner radius support secure seating in a wide range of holders and deliver mechanical strength at the cutting zone. Compatibility with the toolholder is determined by form, clearance angle, tolerance class, clamping method, size and thickness; correct pairing reduces chatter and improves surface finish. The double-sided chipbreaker offers controlled chip formation, lowering the risk of entanglement and easing swarf removal in turning operations.

Coating and grade engineered for mid-range cutting regimes

The PVD coating on this grade is engineered for medium cutting parameters, offering good thermal stability and reduced friction at the cutting interface. The PVD-coated layer together with the carbide core reduces flank wear and maintains a sharper edge longer than uncoated grades in comparable conditions. For workshops seeking reproducible results without extreme cutting speeds, this insert provides a cost-effective balance between productivity and tool life.

Practical advantages in the workshop and production line

As an ISO-standardised turning insert, the plate integrates into established tool systems, simplifying inventory and replacement routines. The cylindrical hole and standard clamping geometry facilitate fast index changes and minimise downtime. Predictable wear behaviour and the insert’s universal application scope reduce the need for frequent grade changes, supporting streamlined process planning and fewer tool changeovers on the shopfloor.

FAQ

What materials is this insert best suited for?
The CNMG090412 AH6225 insert is formulated for machining stainless steels, offering a combination of sharpness and robustness for varied cutting conditions.

How does the AH6225 grade affect tool life?
The AH6225 PVD-coated grade improves wear resistance and edge stability, which typically leads to more predictable tool life in medium-duty stainless steel turning.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, clearance angle, tolerance class, clamping method, size and thickness; the ISO CNMG geometry fits standard CNMG holders when those parameters match.
