DNMG 150404 AH6225 indexable turning insert by Tungaloy — 55° rhombic geometry, PVD-coated carbide

The DNMG150404 AH6225 insert is an ISO indexable turning insert intended for general external and internal turning applications, optimised for machining stainless steels with a sharp yet robust cutting edge and a double-sided chipbreaker.

• PVD-coated carbide for stainless steel machining
• Rhombic 55° geometry for versatile turning
• Double-sided chipbreaker with stable cutting edge
• Cylindrical hole, 4.76 mm thickness, 0.4 mm radius

High-performance grade for stainless steel turning

The PVD-coated AH6225 carbide grade is developed as a universal solution for stainless steel applications, combining a sharp cutting edge with edge stability under varying conditions. This balance reduces the tendency for built-up edge and improves surface finish in medium cutting regimes, which supports higher process reliability and predictable component quality. The coating enhances wear resistance and heat tolerance, extending effective tool life and reducing changeover frequency, thus contributing to a more economical machining process.

Precision geometry to control chips and extend edge life

A 55° rhombic geometry paired with a 0.4 mm corner radius and a double-sided chipbreaker provides controlled chip formation and predictable cutting forces. The rhombic shape offers versatile lead angles for both facing and turning operations, while the chipbreaker design helps to fragment swarf and manage thermal load at the cutting edge. These elements together lower vibration and promote consistent cutting conditions, which is particularly beneficial in batch production or when machining workpieces with varying wall thicknesses.

Seamless integration into ISO-compliant tool systems

Supplied as part of the ISO indexable insert family, compatibility with a toolholder is determined by form, clearance angle, tolerance class, fastening method, size and thickness. The insert features a cylindrical hole for secure clamping, a plate thickness of 4.76 mm and a clearance angle of 0°, enabling straightforward replacement within standard tool systems. Using the correct matching holder and clamping set ensures repeatable positioning and stable machining, reducing setup time and the risk of misalignment during tool changes. The robust specification supports stable chip formation and consistent surface quality across production runs.
