CNMG 090408 AH6225 Turning Insert – ISO CNMG, PVD-coated carbide by Tungaloy

CNMG090408 AH6225 is an ISO‑standard turning insert designed for external and internal turning in industrial machining applications, offering a balance of sharpness and edge stability for varied operating conditions.

• CNMG 090408 ISO insert, rhombic form
• AH6225 PVD-coated carbide grade
• Optimised for stainless steel machining
• Double-sided chipbreaker, 0° clearance

Consistent edge life and predictable wear for stainless steel

The CNMG090408 AH6225 turning insert pairs a modern PVD coating with a proven carbide substrate to extend tool life under varying conditions. The AH6225 grade is developed as a universal solution for machining stainless steel, providing a stable cutting edge that reduces the frequency of index changes and helps maintain component tolerances. For customers evaluating cost of ownership, the result is fewer interruptions for tool changes and a lower total machining cost over the production run.

Clear mounting and ISO compatibility for straightforward integration

The insert follows ISO conventions for shape and sizing, simplifying holder selection and inventory management. With a 09 size, a plate thickness of 4.76 mm and a central bore in a cylindrical style, fitment depends on holder form, free angle, tolerance class, fastening method and dimensions. This standardisation enables easy replacement in compatible CNMG external holders or boring bars and reduces setup uncertainty in mixed-machine environments.

Improved chip control and stable cutting geometry

The rhombic CNMG geometry and double-sided chipbreaker promote consistent chip formation and evacuation during turning operations. The 0° clearance angle and a 0.8 mm corner radius contribute to balanced edge strength and surface finish when performing mid-range cuts. These design choices mean the insert performs reliably across interrupted cuts and variable feed rates, delivering reproducible part quality with reduced risk of edge chipping.

Material and coating advantage for varying machining conditions

The PVD coating enhances abrasive and built-up-edge resistance while preserving a sharp cutting profile, making the grade suitable for changing thermal and mechanical loads. The substrate and coating combination supports a broad material spectrum with a focus on stainless steel, offering a practical compromise between toughness and wear resistance. For production shops aiming for dependable performance, the insert supplies a stable baseline for process planning and repeatable outcomes.

FAQ

Which materials is this insert best suited for?
The CNMG090408 AH6225 Tungaloy turning insert is specified as a universal grade optimised for stainless steel and performs well in a range of similar alloyed steels under mid-range cutting conditions.

How does the AH6225 grade affect machining performance?
AH6225 is a PVD‑coated carbide grade designed to balance a sharp cutting edge with durability; the coating improves wear resistance while the substrate maintains toughness, resulting in predictable tool life for the CNMG insert.

Is the CNMG090408 compatible with standard CNMG holders?
Yes, the insert conforms to ISO CNMG dimensions; compatibility depends on holder form, free angle and fastening method, with the cylindrical‑bore design intended for secure mounting in appropriate external holders or boring bars.

What advantage does the double-sided chipbreaker provide?
The double-sided chipbreaker on this indexable insert supports consistent chip formation and evacuation, improving surface finish and reducing the chance of chip entanglement during turning operations.
