DNMG 150404 AH6225 indexable turning insert — Tungaloy, 0.4 mm radius, with hole

DNMG 150404 AH6225 is an ISO‑standard indexable turning insert designed for external and internal turning, optimised for machining stainless steels under varying conditions

• DNMG 150404 geometry, rhombic 55° cutting angle
• PVD-coated carbide grade AH6225 for stainless steel
• 0.4 mm corner radius for consistent edge strength
• Double-sided chipbreaker with central hole

Higher productivity through a robust grade and proven geometry

The combination of a PVD-coated carbide substrate and the AH6225 grade gives reliable performance when machining stainless steels. The coating increases wear resistance and reduces built‑up edge under intermittent cutting, while the substrate maintains toughness. This results in fewer insert changes and longer uninterrupted machining cycles, so production stays productive and predictable. The insert geometry supports efficient chip formation and contributes directly to lower machining costs per component.

Secure clamping and simple compatibility reduce setup time

Designed to ISO dimensions, the insert fits standard DNMG holders where form, relief angle, tolerance class, fastenings, size and thickness match. The rhombic shape with a central cylindrical hole enables positive location and simple clamping, while the double‑sided design provides cost‑effective indexing. Using holders and clamp sets that comply with ISO ensures repeatable seating and reduces the risk of vibration or chipping, which in turn stabilises machining and improves process repeatability.

Cutting edge geometry for surface quality and edge stability

A 0.4 mm corner radius offers a balanced compromise between edge strength and achievable surface finish for medium cutting depths. The 55° cutting angle typical of DNMG geometry provides accessible cutting forces and directional stability for external and internal contours. The PVD coating minimises friction and enhances heat resistance at the cutting zone, which helps to maintain a sharp cutting edge under changing conditions and supports consistent surface roughness on stainless components.

Practical application advice for workshop and production

Best suited to medium‑duty turning of stainless steels, the insert performs well in both finishing and light roughing when paired with appropriate cutting data and a holder matched for rigidity. Select the chipbreaker and grade according to workpiece material and the rigidity of the setup; a stable machine and correct coolant strategy further extend tool life. For job shops and production environments seeking a reliable, versatile insert for mixed stainless‑steel work, this solution offers a straightforward way to standardise tooling while keeping stock and changeover times low.

FAQ

What materials is this insert suitable for? The DNMG 150404 AH6225 insert is formulated for machining stainless steels; the AH6225 grade and PVD coating deliver controlled chip formation and edge stability for such alloys.

How does the insert locate and clamp in the holder? Location is achieved via the rhombic shape and the central cylindrical hole; the insert seats in an ISO‑compatible pocket and is secured with the appropriate clamping set and screw for reliable repeatability.

Can the insert be indexed to use both sides? Yes, the double‑sided design allows indexing to the unused cutting edges, which extends the effective tool life of each insert and reduces tooling cost per part.

What benefits does the PVD coating provide? PVD coating on the AH6225 grade reduces friction at the cutting interface, improves wear resistance and helps prevent built‑up edge when turning stainless steels under medium cutting conditions.

Is the insert suitable for roughing and finishing? The geometry and 0.4 mm corner radius make the insert versatile for light to medium roughing and finishing; pairing with a rigid holder and adapted cutting data will yield the best combination of tool life and surface quality.
