DNMG 150408 AH905 Wendeplatten - Tungaloy

High wear resistance and consistent edge strength from the PVD-coated carbide grade AH905 deliver reliable machining results; the 55° rhombic geometry and 0.8 mm corner radius combine adaptability with a robust cutting edge. Benefit from a double-sided, ISO‑compliant insert that integrates into standard turning tool systems — order directly via Metav Werkzeuge or request further application advice from the consultants.

DNMG 150408 AH905 — Tungaloy indexable turning insert for turning, PVD‑coated carbide, 55°

The DNMG150408 AH905 is an ISO‑format, rhombic indexable insert engineered for general external and internal turning with a focus on process security and edge stability.

• PVD-coated carbide for wear resistance
• 55° rhombic geometry for versatile turning
• 0.8 mm corner radius for durable edge
• Double-sided chipbreaker, with cylindrical hole

Consistent cutting performance for industrial turning

The insert grade is built on PVD‑coated carbide (AH905), a combination that emphasises wear resistance and improved resistance to chipping under interrupted cuts. This makes the component particularly suitable where a sharp cutting edge and process security are required. The coating reduces flank wear and helps to maintain dimensional accuracy over longer tool life, so machining cycles remain predictable and scrap rates are reduced. Results are stable across a range of turning tasks, from finishing passes to more demanding light roughing, when the matching chipbreaker and holder stability are selected.

Geometry and edge design that support productivity

Designed with a 55° rhombic shape and a 0.8 mm corner radius, the insert balances edge strength and surface finish: the angle gives good approach geometry for a broad range of diameters, while the radius improves load distribution at the tip to resist premature wear. The double-sided chipbreaker aids chip control on both indexable faces and helps maintain consistent cutting forces. With a 4.76 mm thickness, the plate provides the mechanical stiffness required for stable engagement in the tool holder, contributing to reproducible surface quality and reduced vibration during cuts.

System compatibility and practical handling in the workshop

Manufactured to ISO dimensions, the insert features a cylindrical hole for secure clamping and quick indexing in compatible tool holders. Compatibility with a chosen holder is determined by form, clearance angle, tolerance class, fastening method, size and thickness, so the insert integrates smoothly into existing tool systems when the correct matching seat and screw are used. As an indexable insert, it offers straightforward re-indexing and minimal setup time, supporting efficient changeover and inventory management in production environments. For mixed production runs, selecting the appropriate chipbreaker and grade ensures the best balance between tool life and surface finish.
