DNMG 150408 AH120 turning insert – Tungaloy, PVD‑coated carbide, 55°

DNMG150408 AH120 Tungaloy insert for ISO‑standard turning applications, designed for stable clamping and long tool life in external and internal turning operations

• DNMG150408 ISO rhombic insert, 55° cutting angle
• PVD-coated carbide grade AH120 for wear resistance
• 0.8 mm corner radius for sharp entry, fine surface finish
• Double-sided chipbreaker, cylindrical hole for secure clamp

Reliable cutting performance for stable production

The combination of a PVD‑coated carbide substrate and the AH120 grade delivers a balance of wear resistance and toughness, making the insert particularly suitable where a sharp cutting edge and process stability are required. The PVD layer reduces abrasive wear while preserving edge strength, which translates into longer tool life and fewer interruptions for insert changes. For routine turning tasks, this means more predictable cycle times and improved component repeatability.

Secure clamping and consistent surface quality

A rhombic 55° geometry with a 0.8 mm corner radius ensures controlled entry into the material and supports both finishing and light roughing passes. The plate’s cylindrical hole and double‑sided chipbreaker enable positive, repeatable clamping in compatible ISO holders, reducing vibration and contributing to a consistent surface finish. Compatibility to the holder is determined by form, relief angle, tolerance class, fastening method, size and thickness; this insert integrates into standard ISO turning systems as part of a complete setup (insert, holder, backing/clamp and screws).

Productivity through fewer tool changes and safe chip control

Designed for turning operations where uptime and predictability matter, the insert’s geometry and chipbreaker promote controlled chip formation and evacuation. The double‑sided design effectively doubles usable edges per insert, improving cost‑efficiency in batch production. Selecting the right chipbreaker and grade for the workpiece material and machining stability delivers tangible savings in machining time and consumables consumption, supporting a leaner production process.

Application guidance and selection notes

Intended for external and internal turning, the insert is best paired with an appropriate ISO external holder or boring bar and correctly sized clamping set. For materials with specific demands, choose a chipbreaker and grade aligned to the workpiece and machining strategy; the AH120 grade is optimised for applications where wear resistance and edge integrity are required. If further technical data or assistance is needed, consultation with the supplier can clarify holder compatibility and recommended cutting parameters.
