CNMG 090408 AH6225 — Indexable Turning Insert for Turning by Tungaloy (PVD-coated carbide, 80° rhombic form)

The CNMG090408 AH6225 indexable insert is an ISO-standard turning grade engineered for reliable medium machining of stainless steels, combining a sharp yet stable cutting edge with a universal PVD coating for variable conditions.

• ISO-standard rhombic insert form CNMG
• PVD-coated carbide grade AH6225
• Double-sided chipbreaker for consistent chips
• Cylindrical hole and 0° relief angle for secure fixing

Stable cutting performance for medium turning operations

The CNMG insert is built around a PVD-coated carbide substrate that offers a balance between edge sharpness and wear resistance. In practical terms, this means improved tool life under varying cutting conditions and reduced frequency of index changes, which supports steady production flow. The grade is optimised for machining stainless steel, where adhesion and built-up edge can compromise surface finish; the coating helps resist those tendencies while maintaining a predictable flank wear pattern. As a result, process planners can expect fewer unscheduled stops and a more repeatable part quality in batch or single-piece production.

Predictable chip control and geometry that aid surface finish

A rhombic CNMG shape with an 80° approach angle and a 0.8 mm corner radius provides mechanical strength where it matters and the opportunity for good surface integrity at medium depths of cut. The double-sided chipbreaker design supports consistent chip formation across a range of feeds, reducing interruptions from long or erratic chips and improving operator safety. These geometric choices also ease the selection of cutting parameters: the combination of corner radius and approach angle helps absorb vibration while delivering the surface finish expectations typical in general turning tasks.

System compatibility and practical handling in the workshop

Manufactured to ISO dimensions, the insert fits a wide range of standard external and internal turning holders; compatibility is determined by insert form, relief angle, tolerance class, fastening method, size and thickness. The plate thickness of 4.76 mm and the presence of a cylindrical center hole ensure secure clamping in appropriate T-slot or screw-down holders. Inventory and tool-change logistics benefit from the insert’s double-sided use, and the universal AH6225 grade simplifies tool assortment when stainless steels are a common workpiece material. For adapters, clamping sets or replacement screws, Metav Werkzeuge can provide matching components to complete the cutting system.
