CNMG090404 AH6225 ISO turning insert for Drehen by Tungaloy

The CNMG090404 AH6225 is an ISO-standard rhombic turning insert designed for reliable external and internal turning of stainless steels, featuring a PVD-coated carbide grade and a double-sided chipbreaker.

• PVD-coated carbide grade AH6225
• Optimised for stainless steels machining
• 0.4 mm corner radius for versatility
• ISO CNMG 090404 with cylindrical hole

Efficient turning performance for stainless steels

The CNMG090404 AH6225 combines a PVD coating with a robust carbide substrate to provide a sharp, stable cutting edge that performs well under variable conditions. The AH6225 grade is engineered for medium cutting and general-purpose stainless steel workpieces, offering a balance between wear resistance and edge stability. This results in improved process reliability and fewer tool changes during batch production, which supports higher productivity and reduced downtime.

Compatibility and quick tool changes for workshop efficiency

As an ISO-standard insert, compatibility with holders is determined by form, relief angle, tolerance class, fastening, size and thickness; the rhombic shape and cylindrical hole support secure clamping in standard CNMG seats. The double-sided chipbreaker makes the insert indexable, effectively doubling usable edges and simplifying inventory. The nominal 0° relief and standard geometry mean straightforward replacement in common turning holders, enabling fast tool changes and consistent cutting performance across setups.

Durability, geometry and practical application advice

The 0.4 mm corner radius provides a versatile cutting profile suitable for both finishing and light roughing, while the 4.76 mm thickness and 80° wedge angle contribute to mechanical strength and vibration resistance. The PVD layer enhances high wear resistance, extending effective life when machining stainless steels, provided cutting parameters and coolant strategy are adapted to the workpiece and stability. Typical uses include external and internal turning; select the chipbreaker and grade AH6225 to match workpiece hardness and machine rigidity. For tailored cutting data and option selection, Metav Werkzeuge can provide practical recommendations to optimise cycle time and surface finish.
