CNMG 090408 AH6225 Turning insert — ISO rhombic indexable insert by Tungaloy

The CNMG090408 AH6225 is a rhombic ISO turning insert designed for external and internal turning, optimised for medium machining of stainless steel and similar materials.

• ISO rhombic insert CNMG090408
• PVD-coated carbide grade AH6225
• 0.8 mm corner radius, 80° geometry
• Double-sided chipbreaker, cylindrical hole

High process reliability and predictable productivity

The combination of a PVD-coated carbide substrate and the AH6225 grade provides a balance between a sharp cutting edge and a robust edge stability that suits changing cutting conditions. This results in reliable cycle times and reduced tool changes, which improves overall machining efficiency. The rhombic 80° geometry allows secure engagement in both external and internal turning operations, while the double-sided chipbreaker supports consistent chip formation, reducing the risk of interruptions and protecting the workpiece surface.

Consistent edge life and improved surface finish for stainless steel

Designed as a universal grade for stainless steel, the insert’s coating and substrate combine to maintain edge integrity under intermittent and continuous cuts. The 0.8 mm corner radius offers a compromise between strength and finishing capability: it supports stable cutting forces while aiding in achieving improved surface quality. The PVD layer enhances wear resistance and reduces built-up edge, which is particularly beneficial during the machining of stainless steels where adhesion and heat build-up can otherwise compromise results.

Seamless integration and straightforward handling in workshop routines

Compatibility is determined by standard ISO interface dimensions—shape, thickness and mounting configuration—so the insert fits established holders and toolposts where CNMG geometry is specified. The presence of a cylindrical hole and standard thickness simplifies clamping and replacement. Marked by ISO conformity, the design supports fast index changes and predictable setup times, contributing to lower downtime and easier stock management across production shifts.

FAQ

What applications suit this insert best?
The CNMG090408 AH6225 insert is intended for external and internal turning, particularly medium cutting on stainless steel and similar alloys, offering a balance of edge sharpness and stability.

How does the AH6225 grade affect tool life?
AH6225’s PVD-coated carbide composition enhances wear resistance and edge retention under varying cutting conditions, which contributes to longer, more predictable tool life for the CNMG090408 AH6225.

Is the insert compatible with standard ISO CNMG holders?
Yes; the insert follows ISO dimensions for CNMG geometry so it fits compatible external holders and boring bars that accept CNMG090408 inserts.

What chip control can be expected from this geometry?
The double-sided chipbreaker design provides stable chip formation and evacuation in both continuous and interrupted cuts, reducing risk of chip-related interruptions and improving surface finish.

Which identifiers should be used when ordering replacement inserts?
Use the article number 6946672, manufacturer SKU TUN6946672 or the label CNMG090408 AH6225 Tungaloy-Wendeplatte when placing orders to ensure correct item matching.
