DNMG150404 AH8015 ISO turning insert, PVD‑coated carbide, Tungaloy

A DNMG150404 AH8015 indexable insert designed for ISO‑standard external and internal turning of heat‑resistant alloys, offering a balanced combination of wear resistance and edge stability

• PVD‑coated carbide grade AH8015
• For machining heat‑resistant alloys
• Rhombic 55° geometry for stable cuts
• Double‑sided chipbreaker for consistent chips

Longer tool life through balanced material design

The AH8015 grade combines PVD coating with a wear‑resistant carbide substrate to offer a pragmatic balance between abrasive resistance and edge support. This balance reduces flank wear and crater formation under intermittent heat loads, which translates into longer in‑service intervals and fewer insert changes. For production environments handling difficult alloys, the result is measurable improvements in tool life and process stability.

Secure seating and predictable mounting for ISO holders

Compatibility with ISO toolholders is determined by form, clearance angle 0°, tolerance class, attachment, size and thickness. The rhombic 55° geometry and the specified 4.76 mm plate thickness provide a predictable seating surface and stable clamping. As a consequence, set‑up reproducibility improves and vibration susceptibility is reduced, supporting repeatable surface finish and dimensional accuracy on turned components.

Improved chip control reduces interruptions

A double‑sided chipbreaker optimises chip formation for a wide range of cutting conditions typical in turning operations. The chip control design helps to avoid long stringy chips and supports safer material evacuation, which lowers the risk of tool collisions and machine stoppages. With two usable edges per side, the insert maximises cost efficiency while maintaining consistent chip shape across varying feeds and depths of cut.

Easy system integration and pragmatic stock management

The insert integrates into a standard ISO turning system comprising the indexable plate, a matching external holder or boring bar, a shim/clamp set and replacement screws. The presence of a cylindrical locating hole simplifies positive location and clamping, while the 0.4 mm corner radius allows a compromise between edge strength and profile definition. For production planners, this means straightforward inventory control and reduced tooling complexity on mixed‑material production lines.

FAQ

What materials is this insert suited for?
The DNMG150404 AH8015 insert is intended for general machining of heat‑resistant alloys, where the PVD coating and carbide substrate provide a balance of wear resistance and edge stability.

Will the insert fit my ISO turning holder?
Compatibility depends on holder form, clearance, tolerance class, attachment and size; the DNMG150404 is ISO‑standardised and designed for secure seating in matching ISO external holders and boring bars.

How does the AH8015 grade affect tool life?
AH8015 offers a good compromise between wear resistance and edge support, reducing frequent flank wear in challenging materials and thus extending useful cutting life.

How many cutting edges are available per insert?
The rhombic DNMG150404 has two usable edges per side with a double‑sided chipbreaker, increasing the number of indexable edges and improving cost‑efficiency.

What does the 55° geometry mean for turning applications?
A 55° rhombic geometry provides a stable cutting direction and versatility for both external and internal turning, aiding in achieving consistent surface finishes and dimensional control.
