DNMG150412 AH8015 – DNMG ISO rhombic turning insert for turning, Tungaloy, 55°

The DNMG150412 AH8015 is an ISO-standard rhombic turning insert designed for external and internal turning, especially where heat-resistant alloys require a balance of wear resistance and cutting-edge stability.

*PVD-coated carbide AH8015 *Rhombic 55° geometry, 1.2 mm radius *Double-sided chipbreaker, cylindrical hole *ISO-compatible insert, 4.76 mm thickness

Reliable cutting performance for heat-resistant alloys

The combination of a PVD-coated surface and a wear-resistant carbide substrate makes this grade particularly suitable for machining heat-resistant alloys. The AH8015 formulation is balanced between abrasion resistance and edge stability, which reduces the frequency of insert changes and supports a steady production pace. The coating created by the PVD process acts as a hard, thin barrier against adhesive wear and heat build-up; in practice this means longer tool life and more predictable component quality without complex process adjustments.

Compatibility and secure clamping for stable processes

The insert follows ISO-standard geometry, ensuring compatibility with a wide range of DNMG holders and boring bars when form, relief angle, tolerance class, fixing and plate thickness are matched. The 55° rhombic form and the cylindrical hole allow positive and repeatable seating in most tool systems, while the 0° relief angle supports stable cutting conditions in both external and internal turning. Using a properly matched holder, shim and clamping set minimises vibration and runout, which in turn improves surface finish and dimensional consistency.

Practical design that improves productivity and surface quality

A double-sided chipbreaker and a 1.2 mm corner radius are engineered to support controlled chip formation and a reliable cutting edge radius, which benefits surface integrity on the workpiece. The insert’s 4.76 mm thickness and rhombic plate form provide robust support during interrupted cuts and heavier depths of cut. System assembly is straightforward: insert, appropriate holder or boring bar, underlay/clamping set and spare screws — a practical setup that reduces downtime and simplifies tool management on the shop floor.

FAQ

What materials is this insert suited for?
The DNMG150412 AH8015 Tungaloy turning insert is designed primarily for heat-resistant alloys and general turning applications where balanced wear and edge stability are required.

How does the PVD coating help in machining?
The PVD-coated surface on this carbide grade reduces adhesive wear and improves temperature resistance, which extends tool life and maintains cutting-edge integrity during continuous operation.

Is the insert compatible with standard DNMG holders?
Yes. The insert follows ISO geometry; compatibility depends on matching holder form, tolerance class, fixing, size and plate thickness to ensure secure clamping.

What is the effect of the 1.2 mm corner radius?
A 1.2 mm radius provides a compromise between strength and finish: it increases edge robustness for interrupted cuts while helping to achieve a consistent surface quality on turned parts.

Does the chipbreaker support chip control in both roughing and finishing?
The double-sided chipbreaker is designed to control chips effectively across common turning operations, aiding safe evacuation and consistent cutting behaviour.
