DNMG 150408 AH6225 Wendeplatten - Tungaloy

Take advantage of the combination of PVD-coated carbide AH6225 for reliable performance in stainless-steel turning and the cost-efficiency of a double-sided, ISO-standard insert with a robust 0.8 mm corner radius; order the insert directly via Metav Werkzeuge or ask the consultants if further machining data is required.

DNMG150408 AH6225 Tungaloy turning insert — PVD-coated carbide, 55° rhombic geometry

A DNMG150408 AH6225 indexable insert designed for general turning of stainless steels, offering a balanced mix of a sharp, stable cutting edge and universal applicability in medium machining conditions.

• PVD-coated carbide AH6225 for stainless steels
• Rhombic 55° geometry for versatile turning
• 0.8 mm corner radius for robust cutting edge
• Double-sided with cylindrical hole for secure mounting

Consistent edge control for mixed stainless-steel operations

The PVD-coated carbide grade AH6225 combines a sharp, wear-resistant layer with a substrate tuned to maintain a stable edge under varying loads. This results in a reliable cutting performance for machining stainless steels where built-up edge and work-hardening are common issues. The coated surface reduces friction and improves heat resistance, so tool life is extended and component tolerances remain consistent across batches. This behaviour makes the insert especially suitable for shops seeking predictable process windows and a high first-pass yield.

Fast integration with ISO holders and simple mounting logic

Being part of an ISO-standard turning insert family, the plate fits holder systems that match by form, relief angle, tolerance class, fastening method, size and thickness. The neutral 0° relief angle and the 15 mm plate size with 4.76 mm thickness ensure compatibility with a wide range of external and boring holders. The cylindrical hole provides secure clamping and repeatable positioning, reducing set-up time and minimising vibration. Clear conformity to ISO dimensions simplifies procurement and inventory management, allowing quick changeovers and minimal downtime when reindexing the tool.

Productivity gains through geometry and economy of indexing

The 55° geometry of this rhombic insert gives a good compromise between strength and accessibility for both external and internal turning operations. Its double-sided design provides two usable edges per side, lowering the cost per cutting edge and supporting continuous production cycles with fewer tool changes. The 0.8 mm corner radius increases edge robustness without sacrificing surface finish, suitable for medium cutting depths and intermittent cuts. Together, these characteristics support higher metal removal rates and stable chip formation under everyday workshop conditions.

FAQ

What materials is the insert suitable for?
The DNMG150408 AH6225 insert is formulated for reliable machining of stainless steels and performs well in medium-duty turning operations where a sharp, wear-resistant edge is required.

How does the AH6225 coating benefit machining?
The PVD-coated AH6225 grade on this Tungaloy turning insert improves heat resistance and reduces friction, which helps to extend tool life and maintain dimensional accuracy under varying cutting conditions.

Is the insert compatible with standard ISO holders?
Yes. The DNMG150408 follows ISO dimensions, and compatibility with a holder depends on matching form, relief angle, tolerance class, fastening and thickness — the insert’s cylindrical hole and ISO sizing enable straightforward mounting.

What is the advantage of the 55° rhombic geometry?
A 55° geometry provides a balance between cutting edge strength and access to the workpiece, making the plate versatile for both external and internal turning while supporting stable chip control.

How many cutting edges are available per insert?
This is a double-sided indexable insert; reindexing allows multiple usable edges, improving cost-efficiency and reducing downtime for replacements.
