DNMG 150408 AH120 Wendeplatten - Tungaloy

Benefit from the combination of PVD-coated carbide AH120 for extended wear resistance and a precise 55° rhombic geometry with a 0.8 mm corner radius to maintain consistent profile accuracy; order the insert directly via Metav Werkzeuge or consult the advisers for application-specific guidance.

DNMG150408 AH120 — Tungaloy ISO turning insert, 55° rhombic, PVD-coated

The DNMG150408 AH120 is a robust ISO turning insert designed for external and internal turning operations where a sharp cutting edge and process reliability are required.

• PVD-coated carbide AH120 for high wear resistance
• 55° rhombic shape with 0° relief angle
• 0.8 mm corner radius for precise profiling
• Double-sided chipbreaker, cylindrical hole for secure clamping

Reliable cutting performance for productive turning

The insert delivers a stable cutting edge and repeatable performance thanks to the AH120 PVD coating on a hardened carbide substrate. The coating increases resistance to abrasive wear and reduces flank wear during continuous cuts, which leads to longer tool life and fewer indexings. In practical terms, this means lower tooling consumption and more predictable cycle times when machining common turning tasks. The ISO conformity of the geometry facilitates replacement in standard holders; compatibility is determined by form, relief, tolerance class, fastening and the insert's size and thickness.

Predictable chip control and surface quality

Built with a double-sided chipbreaker, the geometry actively controls chip formation in a wide range of cutting conditions, improving evacuation and reducing re-cutting. For users seeking a consistent surface finish, the sharp edge preparation combined with the chipbreaker design reduces built-up edge and chatter risk, especially in interrupted or light finishing cuts. The 0° relief angle and 0.8 mm corner radius promote a defined cutting profile that supports stable cutting forces and helps maintain tolerances on turned features.

Practical compatibility and mounting guidance

The insert’s rhombic form with a 55° included angle and the cylindrical hole ensure secure clamping in suitable ISO holders and boring bars. When selecting a holder, match the insert by geometry, free angle, tolerance class, fastening type, size and thickness to guarantee proper seating and clamping force distribution. The name and designation indicate the series and size, aiding accurate replacement planning and inventory management; for specialised setups or unusual materials, technical advice is recommended to select the correct chipbreaker and grade combination.

Application suitability and material scope

The AH120 grade is engineered as a wear- and fracture-resistant grade for turning applications where a sharp cutting edge and process reliability are both necessary. The insert is suitable for general turning tasks and is particularly effective in stable set-ups where edge integrity and predictable tool life are priorities. For materials that demand different edge life characteristics or higher thermal resistance, consider alternative grades or coatings matched to the specific workpiece material and cutting parameters.

FAQ

What materials is this insert suitable for?
The AH120 grade insert is designed as a wear- and fracture-resistant solution for turning operations; its PVD-coated carbide construction suits a broad range of common turning materials under stable conditions.

How is compatibility with a holder ensured?
Compatibility is achieved by matching the insert geometry, free angle, tolerance class, fastening method, size and thickness to the holder; the DNMG150408 form and the cylindrical hole require a corresponding ISO-compatible clamping system.

Can the insert be used for finishing passes?
Yes — the sharp edge preparation and 0.8 mm corner radius support fine finishing cuts where a defined profile and good surface quality are required.
