DNMG 150404 AH8015 — Indexable turning insert, PVD-coated carbide, 55° rhombic — Tungaloy

DNMG150404 AH8015 is a rhombic, ISO‑norm indexable insert designed for precise external and internal turning of heat‑resistant alloys in general machining applications

• PVD-coated carbide for heat-resistant alloys
• ISO rhombic insert with 55° cutting angle
• Cylindrical hole for secure mounting
• Double-sided chipbreaker for cost efficiency
• 0.4 mm corner radius for fine finishing

Consistent performance through balanced grade technology

The insert is manufactured from carbide with a PVD-coated surface designed to extend tool life when machining demanding materials. The selected AH8015 grade provides a deliberate compromise between wear resistance and cutting-edge stability, which reduces unexpected tool changes and supports predictable cycle times. As a result, production planners can rely on repeatable throughput while maintaining surface quality on heat‑resistant alloys.

Secure compatibility and simple tool set-up

Conforming to the ISO series and the rhombic form, the component fits holders that match form, clearance, tolerance class, fastening and thickness. The cylindrical hole ensures a reliable clamp and repeatable position; the insert thickness of 4.76 mm and the 55° geometry simplify selection of a compatible external holder or boring bar. Clear dimensional data shortens set‑up decisions and reduces downtime during tool changes.

Productivity benefits for general turning tasks

The double‑sided design with an integrated double-sided chipbreaker permits two indexed cutting edges per side, lowering cost per edge and improving process economy. The 0.4 mm corner radius supports fine finishing passes and modest depth cuts with a good balance between edge strength and surface finish. For conventional feeds and speeds, the combination of edge geometry and coating assists in managing built‑up edge and thermal loads when machining heat‑resistant alloys.

Practical guidance for application and selection

When selecting the insert, match the chipbreaker and the AH8015 grade to the workpiece alloy, the chosen stability of the set‑up and the intended machining strategy. In less rigid set‑ups reduce depth of cut and favour finishing parameters to protect the edge; in stable, heavy‑cut scenarios the grade’s wear characteristics help to maintain tool life. Routine visual checks of the cutting edge and adherence to recommended cutting data will preserve performance and support consistent component quality.
