DNMG150408 AH120 — DNMG Indexable Turning Insert for Turning (Tungaloy)

The DNMG150408 AH120 is an ISO‑standard indexable turning insert designed for external and internal turning operations where a sharp cutting edge and consistent process security are required.

• ISO-standard indexable geometry
• PVD-coated carbide for wear resistance
• Double-sided chipbreaker for versatility
• Cylindrical hole, rhombic 55° geometry

Higher uptime through wear‑resistant PVD coating and robust grade

The AH120 grade is a PVD-coated, wear- and chipping‑resistant carbide formulated for turning where edge integrity and process reliability matter. Because the coating enhances hardness and thermal stability, the cutting edge keeps its geometry longer, which reduces the frequency of indexings and tool changes. The combination of a sharp edge and robust substrate supports stable metal removal rates and consistent surface finish during extended cycles, delivering a measurable productivity advantage on repetitive turning tasks.

Fast, reliable clamping and straightforward holder compatibility

Compatibility is ensured by ISO‑conformant geometry: form, clearance angle, tolerance class, fastening method, size and thickness determine the correct holder fit. The rhombic plate form with a 55° principal cutting edge and a cylindrical hole is designed for secure screw clamping in standard DNMG holders. The 0° clearance angle and 4.76 mm plate thickness provide mechanical stability under moderate cutting forces, while the 0.8 mm corner radius balances edge strength and profile fidelity. This predictable fitment reduces setup time and simplifies tool inventory management.

Application guidance for efficient turning operations

Designed specifically for turning, the insert is suitable for both external and internal operations; selection of the chipbreaker and grade should match workpiece material, machining method and assembly rigidity. The double-sided chipbreaker permits two usable edges per side, facilitating economical indexing strategies. When consistent edge performance is a priority—such as in series production or where part tolerance is tight—this insert grade supports reliable results and minimises process interruptions. For bespoke applications or uncertain material mixes, consultation on feed and speed recommendations is advised.

FAQ

What materials is this insert intended to machine?
The DNMG150408 AH120 insert is a PVD‑coated carbide grade optimised for general turning applications where a sharp edge and process security are required; final material compatibility should be verified against specific workpiece alloys.

How does the AH120 grade improve tool life?
The AH120 grade combines a wear‑resistant substrate with a PVD coating that increases thermal stability and hardness, helping the DNMG150408 AH120 insert retain edge geometry and resist chipping under continuous turning conditions.

Is the insert compatible with standard DNMG holders?
Yes, the ISO‑conformant DNMG150408 geometry, including the cylindrical hole and rhombic profile, is designed for secure clamping in standard DNMG holders when dimensions and tolerance classes match.

How many cutting edges are available per insert?
The double‑sided chipbreaker offers multiple usable cutting edges, enabling economical indexing and extended use before replacement of the DNMG150408 AH120 insert is required.

What are the key dimensional specifications to check when selecting a holder?
Check corner radius (0.8 mm), plate size (15 mm), thickness (4.76 mm), clearance angle (0°) and the cylindrical hole position to ensure proper seating and clamping of the DNMG150408 AH120 insert.
