DNMG150412 AH8015 Tungaloy turning insert — PVD-coated carbide, 55° rhombic geometry

A DNMG150412 AH8015 Tungaloy turning insert optimised for external and internal turning of heat‑resistant alloys, offering a balance of wear resistance and edge stability for reliable shop‑floor performance.

• ISO DNMG geometry, 55° rhombic
• PVD-coated carbide for heat-resistant alloys
• 1.2 mm corner radius for stable cutting
• Double-sided chipbreaker, 4.76 mm thickness

Consistent results when machining heat-resistant alloys

For applications involving elevated temperatures, the combination of a PVD coating and a carbide substrate provides improved resistance to abrasive and thermal wear while maintaining cutting‑edge integrity. This insert’s design is intended to reduce flank wear and preserve dimensional accuracy over extended tool life, which translates into fewer tool changes and less downtime. The result is a more predictable machining process and improved overall equipment effectiveness.

Geometry and form deliver process stability

The 55° rhombic geometry with a 1.2 mm corner radius gives a stable contact area and predictable chip formation during turning. The rhombic shape supports a range of approach angles, while the 0° clearance face promotes consistent contact with the workpiece. These features make the insert compatible with standard ISO holders and boring bars when the holder’s form, clearance angle and tolerance class match the insert specifications, ensuring simple integration into existing tool systems.

Coating and substrate work together for balanced performance

A PVD-coated carbide grade offers a compromise between hardness and toughness that is ideal for general turning of heat‑resistant alloys. The coating enhances surface hardness and reduces built-up edge, while the carbide core provides the necessary edge stability under intermittent loading. Where finish quality and repeatability are required, this combination helps to achieve consistent surface integrity without sacrificing tool life.

System compatibility and practical handling

The insert is supplied in the ISO DNMG format and is designed to be used with a matching external holder or boring bar, plus the appropriate clamp set and replacement screws for secure fixation. The plate’s cylindrical hole and standard dimensions simplify mounting and replacement in production environments. Selecting the correct chipbreaker variant and grade for the workpiece material and stability level will maximise productivity and process reliability in turning operations.

FAQ

Which materials is this insert suitable for? This insert is formulated for turning heat‑resistant alloys; the AH8015 grade and PVD coating on the DNMG150412 AH8015 insert give a good balance of wear resistance and edge stability for such materials.

What geometry does the insert have and why does it matter? The DNMG150412 AH8015 insert features a 55° rhombic geometry, which provides flexibility in approach angles and contributes to process stability during both external and internal turning.

How does the coating affect performance? The PVD coating on the DNMG150412 AH8015 insert increases surface hardness and reduces adhesion, which helps to lower flank wear and maintain consistent cutting performance in demanding turning operations.

Is this insert compatible with standard ISO holders? Yes; the DNMG150412 AH8015 insert follows ISO DNMG dimensions and is intended to be used with matching external holders or boring bars when form, free angle and tolerance class are compatible.

What is the significance of the 1.2 mm corner radius? A 1.2 mm corner radius on the DNMG150412 AH8015 insert gives enhanced edge strength and helps to distribute cutting forces, improving stability on interrupted cuts and when machining less rigid setups.
