DNMG150612 AH6225 turning insert — ISO-compliant rhombic insert for medium turning by Tungaloy

DNMG150612 AH6225 is an ISO-standard turning insert engineered for general turning applications, optimised for stainless steels and variable machining conditions

• ISO rhombic 55° geometry, ISO-compliant
• PVD-coated cemented carbide grade AH6225
• 1.2 mm corner radius for stable engagement
• Double-sided chipbreaker, with cylindrical hole

Consistent cutting performance for stainless steels

The PVD-coated cemented carbide grade offers a balance between edge sharpness and wear resistance, designed specifically for machining stainless steels under varying conditions. This combination reduces built-up edge formation and improves surface finish during medium cuts. The ISO-standard geometry ensures predictable cutting behaviour and straightforward comparison with other inserts, supporting process planning and tool selection in job shops and production environments.

Stable edge life and machining reliability

A comparatively sharp, yet durable cutting edge in the AH6225 grade provides consistent results over repeated operations, translating into fewer interruptions and steadier part quality. The double-sided chipbreaker extends usable edges and supports reliable chip formation, while the robust coating mitigates flank wear. These factors contribute to lower tooling costs per component and help maintain cycle times in batch production or mixed-series turning.

Secure clamping and straightforward holder compatibility

The rhombic 55° geometry, 6.35 mm thickness and cylindrical hole permit secure mounting in compatible external holders and boring bars. Compatibility depends on form, clearance angle, tolerance class, clamping and size; matching these criteria ensures correct seat and clamping force. The 1.2 mm corner radius smooths engagement at entry and exit, reducing vibration and aiding dimensional stability on long overhangs or less rigid setups.

Productivity advantages and application guidance

Using this ISO insert supports a predictable machining window, with benefits in surface finish and reproducibility for medium turning tasks. The design promotes efficient chip evacuation and steady tool life, which together help to reduce changeover frequency and increase effective machine uptime. Application advice and cutting data are available for integration into existing tool systems, and Metav Werkzeuge can provide support for optimising feeds, speeds and holder selection.

FAQ

What materials is this insert designed for?
The DNMG150612 AH6225 Tungaloy turning insert is formulated primarily for stainless steels, offering improved resistance to built-up edge and consistent surface quality in variable machining conditions.

How does the AH6225 grade affect tool life and finish?
The AH6225 PVD coating and carbide substrate provide a balance between edge sharpness and wear resistance, so the DNMG150612 insert achieves predictable tool life and reliable surface finish during medium turning operations.

Is the insert reversible or indexable?
Yes, the insert is double-sided with a chipbreaker on both cutting faces, allowing multiple indexing positions before disposal and improving cost-efficiency per edge.

What should be checked for holder compatibility?
Holder compatibility depends on the insert form, clearance angle, tolerance class, clamping method, size and thickness; ensure the holder matches the DNMG150612 geometry and the cylindrical hole specification for correct seating.

Does the cylindrical hole affect mounting options?
The cylindrical hole provides a secure central reference and is compatible with a range of clamping systems in ISO holders; correct clamping ensures repeatable positioning and stable cutting performance.
