DNMG150408 AH8015 — ISO rhombic turning insert, PVD‑coated carbide, 55° (Tungaloy)

The DNMG150408 AH8015 is an ISO‑standard rhombic turning insert designed for general external and internal turning, offering balanced wear resistance and edge stability for machining heat‑resistant alloys.

• PVD-coated carbide for balanced wear and edge stability
• ISO rhombic DNMG 55° geometry
• 0.8 mm corner radius for robust finishes
• Compatible with standard ISO holders

Faster, more predictable machining of heat‑resistant alloys

The PVD‑coated carbide grade AH8015 is engineered as a first choice for general machining of heat‑resistant alloys, giving a balance between wear resistance and cutting‑edge stability. This balance translates into longer periods between tool changes and more consistent component tolerances, which supports higher overall productivity. The coating enhances oxidation and abrasion resistance at elevated cutting temperatures, reducing flank wear and helping to maintain part quality during extended cycles.

Geometry and dimensions that secure reliable seating and surface quality

With its 55° rhombic geometry, 0° clearance, and a 0.8 mm corner radius, the insert provides a stable cutting edge for a broad range of turning operations. The 4.76 mm plate thickness and cylindrical hole ensure positive clamping in compatible holders, while the rhombic form permits both external and internal applications where access or orientation is a factor. These design elements minimise chatter and help achieve reproducible surface finishes on demanding alloys.

System compatibility for efficient tool management

The indexable plate is delivered as part of the ISO‑compliant system approach: the insert, a matching external holder or boring bar, a locating shim or clamp set, and replacement screws form a complete, easy‑maintainable setup. The double‑sided chipbreaker arrangement permits economical use of each plate side, reducing tooling costs per component when compared with single‑use cutters. Standardisation through the ISO series simplifies stock handling and replacement planning across production lines.

Practical selection guidance for stable production results

Choose the appropriate chipbreaker and mounting stability according to the workpiece material and machining conditions: for less rigid setups, favour insert grades and chipbreakers that prioritise edge strength and controlled chip formation; for stable conditions, prioritise grades that offer enhanced wear resistance for longer tool life. The AH8015 range is optimised for a wide material spectrum of heat‑resistant alloys and delivers a reliable compromise between productivity and tool longevity, making it suitable for batch and continuous production environments.

FAQ

Is the DNMG150408 AH8015 insert compatible with standard DNMG holders? Yes. The DNMG150408 AH8015 is ISO‑standard and designed to fit holders specified for DNMG150408 geometry, taking into account form, relief angle, tolerance class, clamping method, size and thickness.

For which materials is this grade recommended? The AH8015 grade is primarily recommended for heat‑resistant alloys as a first choice for general machining, offering a compromise between wear resistance and cutting‑edge stability for stable production.

Does the insert offer indexable/reversible cutting edges? Yes. The plate is double‑sided with a double‑sided chipbreaker design, allowing rotation or indexing to present fresh cutting edges and extend usable tool life.

How does the geometry influence surface finish and stability? The 55° rhombic form, 0.8 mm corner radius and 4.76 mm thickness contribute to secure seating in the holder, reduced vibration and consistent surface finish, particularly in stable clamping conditions.

Which system components are required for correct mounting? A matched external holder or boring bar, a locating shim/clamp set and the appropriate replacement screw are required; the cylindrical hole and ISO‑compliant form ensure correct positioning and clamping within the system.
