DNMG150404 AH6225 turning insert by Tungaloy — PVD carbide, 0.4 mm radius

DNMG150404 AH6225 Tungaloy turning insert for ISO-conforming external and internal turning with a rhombic 55° geometry and double-sided chipbreaker suitable for varied machining conditions

• PVD-coated carbide grade AH6225
• Universal for stainless steels and mixed materials
• 0.4 mm corner radius for stable cutting
• 55° rhombic shape with cylindrical hole

Consistent geometry for ISO turning systems and predictable interchangeability

The rhombic 55° geometry and ISO designation ensure straightforward integration into standard turning tool systems. With the ISO-series construction, compatibility with holders is determined by form, relief angle, tolerance class, mounting style, size and thickness; this delivers predictable clamping and repeatability across tool changes. The presence of a cylindrical mounting hole and standard dimensions supports rapid replacement and reduces setup variance, which contributes to steady component tolerances in serial production.

AH6225 PVD-coated carbide: balance of edge sharpness and robustness

The AH6225 grade is a PVD-coated carbide developed for universal performance on stainless steels, offering a sharp yet resilient cutting edge suited to medium-duty turning and fluctuating conditions. PVD coating enhances wear resistance and heat tolerance while the carbide substrate preserves edge stability, which together extend tool life and maintain surface finish. For engineers seeking an economical route to reliable productivity, this combination reduces unscheduled tool changes and stabilises process windows.

Chip control and practical handling for everyday turning

A double-sided chipbreaker design provides controllable chip formation in both external and internal turning operations, reducing the risk of entanglement and improving swarf evacuation. The insert’s 0.4 mm corner radius helps bridge the demands between finishing and light roughing: it moderates edge strength while allowing for improved contour fidelity. As part of an ISO insert system, the unit works with the appropriate outer holder, shim/clamp set and fastening screw, enabling efficient inventory management and rapid replacement in the workshop.
