CNMG 090412 AH6225 Tungaloy indexable insert — PVD-coated carbide for turning

The CNMG090412 AH6225 is an ISO-standard indexable turning insert designed for external and internal turning, offering a sharp yet robust cutting edge for variable machining conditions.

• PVD-coated carbide grade AH6225
• Universal grade for stainless steels
• Rhombic CNMG shape, 80° included
• Double-sided insert with cylindrical hole

High-performance cutting where consistency matters

The PVD-coated carbide composition of this indexable plate provides a balanced combination of edge sharpness and wear resistance. The AH6225 grade is optimised for stainless steels, delivering repeatable cutting results in mixed-series production where material batches and cutting conditions change. Because the coating improves thermal resistance and friction behaviour, the insert supports longer tool life and reduces the frequency of index changes, which contributes to a more efficient production flow and lower overall machining costs.

Secure fit and predictable set-up for fast changeovers

Designed to ISO dimensions, the insert’s rhombic CNMG form and cylindrical hole ensure compatibility with standard external holders and boring bars when form, relief angle, tolerance class, fastening and thickness match. The 80° included angle and 1.2 mm corner radius provide a compromise between strength and form-holding for finishing and medium-turning operations. The 0° relief angle indicates a neutral clearance suitable for many holder geometries; operators should verify holder compatibility to achieve the intended cutting geometry and repeatable clamping behaviour.

Practical benefits for everyday workshop use

As a double-sided indexable insert, the plate offers economical use of cutting edges — each face contributes to uptime before replacement. The nominal thickness of 4.76 mm and ISO size designation facilitate quick identification and stock management. For workshops seeking a reliable standard for stainless-steel turning, this plate reduces downtime through predictable wear patterns and straightforward edge indexing, supporting both one-off jobs and series production demands.

FAQ

What materials is this insert intended for?
The CNMG090412 AH6225 insert is intended primarily for stainless steels; the AH6225 grade offers a universal balance between edge sharpness and wear resistance for varied stainless-steel machining.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, relief angle, tolerance class, fastening method, size and thickness; the insert conforms to ISO CNMG dimensions, so it fits compatible CNMG holders and boring bars when those parameters match.

How many cutting edges are available per insert?
This is a double-sided CNMG plate; both sides provide usable cutting edges, increasing the number of indexable edges before replacement.

What are the key benefits of the AH6225 grade?
The AH6225 PVD-coated carbide grade combines thermal stability and a stable cutting edge, making it suitable for medium cutting depths and variable conditions commonly encountered when turning stainless steels.
