CNMG 090412 AH6225 indexable turning insert, PVD-coated carbide, 1.2 mm corner radius — Tungaloy

The CNMG 090412 AH6225 is an ISO‑standard indexable insert designed for efficient external and internal turning, offering a balanced cutting edge for medium machining of rostfreie Stähle.

• PVD-coated carbide grade AH6225
• Double-sided chipbreaker
• Rhombic CNMG form, 80° included angle
• 1.2 mm corner radius for edge stability

Consistent productivity from a stable cutting edge

The insert’s PVD‑coated cemented carbide grade AH6225 is formulated for a broad range of rostfreie Stähle, delivering a sharp yet resilient cutting edge under variable conditions. The coating reduces adhesion and heat uptake, which helps maintain cutting performance over longer tool life and reduces the need for unscheduled tool changes. For production environments prioritising cycle time and consistency, this geometry and material combination supports predictable removal rates and surface finish while keeping machining windows narrow.

Clear explanation of key features and how they benefit operations

The double-sided chipbreaker and rhombic CNMG form provide two usable cutting edges per index, improving economy and inventory efficiency. A corner radius of 1.2 mm increases edge strength and dampens vibration during interrupted cuts, while the 0° clearance angle is suited to conventional turning setups where rigidity and stability are prioritised. The PVD layer minimises built-up edge on rostfreie Stähle, and the cylindrical hole ensures secure clamping in compatible holders — together these features simplify process planning and reduce scrap rates from edge breakdown.

Integration into tooling systems and selection guidance

As an ISO‑standard insert, compatibility with holders depends on form, free angle, tolerance class, fastening method, size and thickness. The CNMG090412 format makes it straightforward to match with common external holders or boring bars; selection of the appropriate chipbreaker and grade should be based on workpiece material, machining parameters and machine stability. For mixed production runs the universal nature of this grade reduces tool changes and streamlines tooling logistics, supporting leaner set‑ups and faster changeovers.

FAQ

What materials is this insert suitable for?
The CNMG 090412 AH6225 insert is formulated as a universal grade for rostfreie Stähle and is particularly effective in medium turning operations where a balance of sharpness and edge stability is required.

How does the PVD coating affect performance?
The PVD coating on the AH6225 grade reduces adhesion and wear on the cutting edge, improving tool life and maintaining surface quality during turning with the indexable insert.

Can the insert be used on internal boring bars as well as external holders?
Yes, the CNMG090412 format is compatible with both external holders and appropriate boring bars, provided the holder matches the ISO form, size and fastening specifications.

How many cutting edges are available per insert?
Thanks to the double-sided chipbreaker and CNMG geometry, the insert offers multiple usable edges, increasing economy per indexable tool and reducing tooling costs.
