DNMG150408 AH8015 indexable turning insert, ISO DNMG 150408, for turning — Tungaloy

A DNMG150408 AH8015 indexable turning insert from Tungaloy for general turning applications, engineered for reliable performance on heat‑resistant alloys and a wide range of steels.

• PVD-coated carbide AH8015
• Double-sided chipbreaker
• Rhombic DNMG shape, 55° geometry
• 0.8 mm corner radius, cylindrical hole

Longer tool life through a balanced PVD grade

The combination of a PVD-coated surface and a cemented carbide substrate provides a dependable mix of wear resistance and edge strength, which translates into fewer insert changes and more productive machining cycles. The AH8015 grade is described as a first choice for machining heat‑resistant alloys, offering a compromise between hardness and toughness that helps maintain cutting-edge integrity under variable cutting forces. This results in extended tool life and more predictable replacement intervals, supporting stable production planning.

Better chip control reduces stoppages and rework

A double-sided chipbreaker integrated into the insert geometry delivers consistent chip formation during both external and internal turning operations. Stable chip control reduces the risk of entanglement and tool damage, which in turn lowers the occurrence of interrupted cycles and scrapped parts. The rhombic DNMG form and the 55° approach angle contribute to a favourable cutting force vector, helping to maintain surface finish and dimensional stability even when working with tougher alloys.

Straightforward mechanical compatibility with ISO systems

Compatibility with a toolholder depends on geometric factors such as form, clearance angle, tolerance class, fastening style, size and thickness. The insert has a clearance angle of 0°, a plate thickness of 4.76 mm and a 15 mm nominal size, so mechanical fit is determined by the corresponding ISO DNMG‑capable holders and clamping sets. Specifying the matching holder by DNMG interface avoids trial‑and‑error assembly and ensures repeatable seating and clamping accuracy for consistent machining results.

Practical guidance for application and selection

Select the AH8015 grade and the DNMG geometry when the machining task demands a balance between edge stability and resistance to abrasive wear, particularly on heat‑resistant alloys. The 0.8 mm corner radius moderates cutting edge strength and surface finish — a larger radius improves edge robustness, while smaller radii favour fine surface requirements. For uncertain cases, match the chipbreaker style to the workpiece material and the rigidity of the setup: the double‑sided breaker is versatile and suited to a range of feed rates and depths of cut.

FAQ

Which machining operations is this insert suited for?
The DNMG150408 AH8015 Tungaloy indexable insert (SKU 6741654-Tungaloy) is intended for both external and internal turning operations and is designed as a general‑purpose solution for those applications.

What materials is the AH8015 grade optimised for?
AH8015 is a PVD‑coated carbide grade recommended as a first choice for machining heat‑resistant alloys and provides a balanced combination of wear resistance and cutting‑edge stability.

Is the insert indexable and reversible?
Yes — the insert is double‑sided with a reversible design, allowing both cutting edges to be used and improving economy per insert compared with single‑edge alternatives.

How is fit with the toolholder ensured?
Compatibility for the DNMG150408 insert is ensured by matching the insert form, clearance angle (0°), tolerance class, fastening method, size (15 mm) and thickness (4.76 mm) to a corresponding ISO‑compatible DNMG holder and clamping set.

What are the key geometry values to consider when planning a setup?
Important values are the 55° approach geometry, 0.8 mm corner radius, plate thickness 4.76 mm, and the presence of a cylindrical locating hole; these determine cutting forces, edge strength and seating in the holder.
