DNMG 150404 AH120 indexable turning insert for ISO turning — Tungaloy

The DNMG 150404 AH120 is an ISO‑standard, rhombic indexable insert designed for external and internal turning operations where a sharp cutting edge and consistent process security are required

• PVD‑coated AH120 carbide for wear resistance
• Double‑sided chipbreaker for stable chip control
• Rhombic ISO insert, 55° cutting angle
• 0.4 mm corner radius, 4.76 mm thickness

Stable chip control and prolonged tool life

The combination of a PVD coating with the AH120 carbide substrate provides enhanced resistance to abrasive wear and edge breakage, resulting in a reliable cutting edge over extended runs. The double‑sided chipbreaker is engineered to generate short, controllable chips under a wide range of cutting conditions; this improves process stability and reduces interruptions for chip clearance. For operations with frequent tool changes, the grade’s resistance to chipping also translates into lower tooling costs per component and predictable performance in production.

Geometry tuned for accuracy and surface finish

A rhombic form with a 55° cutting angle and a 0.4 mm corner radius balances edge strength and surface quality. The moderate corner radius increases the insert’s resistance to mechanical shock while still permitting a fine surface finish when axial and radial engagements are set accordingly. The 4.76 mm plate thickness contributes to rigidity in the clamped system, reducing vibration and helping to maintain dimensional accuracy in external and internal turning tasks. These geometric parameters make the insert suitable for on‑centre turning and light profiling where repeatable tolerances matter.

ISO compatibility and secure mounting in systems

Produced to ISO standards, the insert’s compatibility with a holder is defined by shape, relief angle, tolerance class, mounting style, size and thickness. The system generally comprises the indexable insert, a suitable external holder or boring bar, a backing shim/clamping set and replacement fastening screws, which together determine clamping rigidity. Selection of the correct chipbreaker and grade should be matched to the workpiece material, machining strategy and machine stability to ensure process security. Metav Werkzeuge can provide assistance in matching the insert to the correct holder and clamping components.

Practical applications and selection guidance

Intended for general turning duties, the insert is appropriate when a sharp cutting edge and consistent performance are essential. The AH120 grade is geared towards operations where wear resistance and protection against edge failure are priorities; the double‑sided chipbreaker broadens applicability across varying cut depths and feed rates. For best results, choose the chipbreaker and insert grade according to the material being machined and the rigidity of the setup; this preserves tool life and optimises cycle time without compromising surface integrity.

FAQ

What holders are compatible with this insert?
Compatibility depends on holder geometry and clamping method; the DNMG 150404 AH120 insert fits ISO‑standard holders matching its rhombic form, size and thickness — confirm holder form, tolerance and fastening to ensure proper seating.

Which machining operations suit this grade best?
The AH120 grade is intended for turning where a sharp edge and process security are required; it performs well in general external and internal turning applications with stable chip control provided by the double‑sided chipbreaker.

How does the 0.4 mm corner radius affect cutting?
A 0.4 mm corner radius increases edge robustness and reduces the risk of chipping under interrupted cuts while still allowing a good surface finish when feeds are selected appropriately for the DNMG 150404 insert.

Is the coating suitable for high temperatures?
The PVD coating on the AH120 grade offers improved wear resistance and helps maintain edge integrity at elevated temperatures typical of turning operations, contributing to longer tool life.

What does the cylindrical hole mean for mounting?
The cylindrical hole provides a secure central locating and fastening point within compatible ISO holders; combined with the correct shim and clamping set it ensures stable, repeatable seating of the indexable insert.
