DNMG150604 AH6225 Tungaloy turning insert — rhombic 55°, PVD‑coated carbide

DNMG150604 AH6225 Tungaloy turning insert is an ISO‑standard rhombic insert for external and internal turning, optimised for medium‑duty machining of rostfreier Stahl with a sharp yet stable cutting edge.

• PVD‑coated carbide for high wear resistance
• Designed for rostfreier Stahl machining
• Rhombic DNMG 55° with cylindrical hole
• Double‑sided chipbreaker, 0.4 mm corner radius

Consistent cutting performance for rostfreier Stahl

The AH6225 grade is a PVD‑coated carbide developed as a universal option for rostfreier Stahl, balancing edge sharpness and stability under varying conditions. As an ISO‑conforming rhombic insert, it provides a defined 55° cutting geometry that simplifies process planning and helps maintain surface finish when tooling parameters change. The PVD coating improves wear resistance and reduces built‑up edge, which in turn supports longer tool life and fewer insert changes—benefits that translate to steadier throughput on the shop floor.

Simple integration into ISO turning systems

Compatibility with a toolholder is determined by insert geometry, clearance, tolerance class, fastening, size and thickness; this turning insert respects those ISO markers. The cylindrical hole and standard form make it straightforward to mount in matching external holders or boring bars, and the 0° clearance specification is reflected in holder selection and setup. Clear, repeatable mounting reduces set‑up time and ensures that process capability studies remain valid across tool changes.

Practical machining advantages and chip control

A double‑sided chipbreaker tailored to general turning keeps chips compact during external and internal operations, reducing downtime for chip handling. The 0.4 mm corner radius contributes to a robust cutting edge that resists chipping during transient cuts while still allowing reasonable corner strength for finishing passes. These characteristics support predictable tool wear and more consistent cycle times, offering a measurable improvement in productivity when compared with non‑optimised grades.

Key specifications and handling notes

The insert is supplied in ISO DNMG150604 form with a 6.35 mm thickness and a 15 mm inscribed circle, making it suitable for a wide range of standard holders. The carbide substrate provides the core strength; the PVD finish enhances surface endurance. For best results, select a holder and clamping kit rated for the DNMG form and verify the clearance and tolerance class to match the insert’s geometry. Regular inspection of the clamping screw and seat will help maintain repeatable accuracy in serial production.

FAQ

What materials is this insert suitable for?
The DNMG150604 AH6225 turning insert is intended primarily for rostfreier Stahl and other materials where a sharp, stable PVD‑coated carbide edge offers the best compromise between finish and tool life.

How is the insert mounted in a toolholder?
Mounting requires a compatible DNMG‑form holder with matching seat and fastening; the insert uses a cylindrical hole and standard clamping arrangement for secure fixation.

What are the main advantages of the AH6225 grade?
The AH6225 grade combines a PVD coating with a carbide substrate to deliver improved wear resistance, consistent cutting edge stability and reliable performance in medium‑duty stainless turning.

Can the insert be used for internal as well as external turning?
Yes, the rhombic geometry and double‑sided chipbreaker make the insert suitable for both external and internal turning applications when paired with the appropriate holder or boring bar.

Is the insert reversible?
The DNMG geometry with a double‑sided chipbreaker allows the insert to be used on both faces, providing two cutting edges per index.
