DNMG150408 AH8015 turning insert — PVD-coated carbide, 0° clearance — Tungaloy

The DNMG150408 AH8015 is an ISO‑standard rhombic turning insert designed for external and internal turning of heat‑resistant alloys, offering a balanced combination of wear resistance and edge stability for productive machining.

• PVD-coated carbide grade AH8015
• Rhombic 55° geometry for secure seating
• 0° clearance angle for stable cutting
• Double-sided chipbreaker, cylindrical hole

Consistent performance for general turning of heat-resistant alloys

The PVD‑coated AH8015 carbide grade is formulated as a first choice for general machining of heat‑resistant alloys, providing an effective balance between wear resistance and edge stability. This balance reduces flank wear and maintains a consistent cutting edge under thermal loads, which translates into predictable tool life and reliable surface finish. The rhombic geometry combined with the PVD coating supports repeatable material removal rates and lower scrap rates in batch production, making the insert well suited to routine and mixed‑material turning tasks.

Geometry that improves stability and process reliability

A 55° rhombic shape with a 0.8 mm corner radius and 0° clearance gives mechanical rigidity at the cutting zone and promotes controlled chip formation. The double-sided chipbreaker design and the cylindrical centre hole ensure secure mounting in ISO‑compatible holders; compatibility depends on holder form, relief angle, tolerance class, clamping method, size and thickness. For workshops less familiar with insert geometry: a smaller corner radius reduces cutting forces for finish passes, while the rhombic angle allows convenient indexing and economical use of each cutting edge, enhancing overall process stability.

Practical integration and application advice for workshop use

The insert is delivered in an ISO specification intended to be used with a matching external holder, screw/clamping set and, where required, shim or support. It is suitable for both external and internal turning operations when the correct chipbreaker and grade are selected for the workpiece and machining conditions. For best results, pair the insert with a holder that matches the form and tolerance class, ensure secure clamping with the prescribed screw torque, and choose cutting parameters that correspond to the alloy’s machinability and the machine tool’s stiffness. The result is reduced downtime, improved surface quality and repeatable component tolerances.
