DNMG150408 AH120 indexable turning insert — rhombic 55° for precision turning by Tungaloy

The DNMG150408 AH120 is an ISO‑standard rhombic indexable insert for external and internal turning, engineered for stable chip formation and consistent process performance when a sharp cutting edge and elevated wear resistance are required.

• DNMG150408 ISO geometry for universal turning
• AH120 PVD-coated carbide for wear resistance
• Double-sided chipbreaker for reliable chip control
• Rhombic 55° shape with 0° clearance

Precise edge life and thermal stability for uninterrupted turning

The AH120 is a PVD-coated carbide grade designed for a balance of wear resistance and edge toughness, which helps maintain cutting performance over longer tool paths. The thin, hard PVD coating reduces flank and crater wear while preserving a sharp cutting edge, resulting in consistent dimensional accuracy and extended tool life. For production environments where reproducible results and reduced tool change frequency matter, this coating-technique combination contributes directly to lower downtime and improved machining economy.

Geometry and mounting that simplify tool system setup

The rhombic 55° geometry with a 0° relief angle provides versatile approach angles suitable for a wide range of turning tasks. The insert’s cylindrical hole and standard ISO form ensure holder compatibility when matched by form, relief angle, tolerance class, fastening method, size and thickness. This makes integration into an existing turning system straightforward: the insert pairs with an appropriate external holder or boring bar along with the necessary clamp set and fastening screws to form a stable assembly.

Chip control and surface quality with minimal rework

Equipped with a double-sided chipbreaker, this insert actively shapes and controls chips during cutting, reducing the risk of tangled swarf and improving chip evacuation in both roughing and finishing passes. Better chip control contributes to consistent surface finishes and fewer interruptions in automated or long-run operations. When combined with the grade’s edge stability, the result is reliable surface quality and fewer downstream processing steps.

Dimensions and practical considerations for selection

Key dimensions such as the 0.8 mm corner radius and 4.76 mm plate thickness influence feed choices and depth of cut; the modest corner radius supports a balance between strength and fine surface finish. The insert’s 15 mm size and ISO designation simplify selection for standard holders. Selection should consider workpiece material and desired cutting parameters: the system is optimised for turning tasks where process reliability and a sharp cutting edge are priorities, and it performs especially well in applications demanding consistent, repeatable results.

FAQ

What materials is this insert suitable for?
The DNMG150408 AH120 insert is a PVD‑coated carbide grade formulated for general turning tasks where a sharp cutting edge and wear resistance are required; compatibility with specific workpiece materials should be confirmed against machining parameters.

How does the AH120 grade affect tool life?
The AH120 PVD coating improves wear resistance and edge stability, which typically extends insert life under comparable cutting conditions and supports consistent component quality.

Which holder types fit this insert?
Compatibility depends on form, relief angle, tolerance, fastening and size; the insert is designed for use with standard external holders or boring bars that accept ISO DNMG150408 inserts and the associated clamp set and screws.

Can the insert be reversed for a second cutting edge?
Yes, the insert is double‑sided with a double-sided chipbreaker, allowing indexation to a fresh edge to extend the usable lifetime within the same insert.

What does the 0.8 mm corner radius mean for surface finish?
A 0.8 mm corner radius offers a compromise between edge strength and surface quality—providing robust performance on moderate feeds while still enabling good surface finishes when parameters are set accordingly.
