DCMT 070204 AH8015 ISO turning insert — PVD-coated carbide by Tungaloy

DCMT070204 AH8015 is an ISO rhombic turning insert designed for external and internal turning where a balance of wear resistance and cutting-edge stability is required.

• ISO rhombic insert DCMT 07 size
• PVD-coated carbide AH8015 grade
• Single-sided chipbreaker for reliable chips
• Cylindrical hole with 40°–60° countersink

Consistent cutting performance for heat-resistant alloys

The PVD-coated carbide grade AH8015 is formulated as a first choice for general machining of heat-resistant alloys, offering an optimum balance between wear resistance and cutting-edge stability. As an ISO-spec insert, it is engineered to deliver repeatable results in both roughing and light finishing passes. The wear characteristics of the coating reduce flank wear development, which translates into fewer insert changes and more stable cycle times on production runs when machining demanding materials.

Secure clamping and defined geometry for repeatability

A stable toolholder interface is central to process reliability: the rhombic shape with a 55° lead angle, 0.4 mm corner radius, and 7° rake creates a defined cutting geometry that supports predictable chip formation and surface quality. The insert’s cylindrical hole with one-sided countersink (40°–60°) enables secure mechanical clamping and simple replacement on standard ISO holders. With a plate thickness of 2.38 mm and standard 07 size, the component sits reliably in the clamping pocket, reducing micro-movement and improving tolerance adherence across repeated indexings.

Improved chip control and productivity

The integrated single-sided chipbreaker provides controlled chip segmentation for a wide range of turning conditions, reducing entanglement and enabling safer, higher-feed operations where chip evacuation is critical. By promoting consistent chip shapes, the insert helps to protect the workpiece finish and to maintain stable cutting forces, supporting higher throughputs and reduced downtime. These productivity gains stem from a rational combination of cutting geometry and the balanced properties of the PVD-coated hardmetal grade.

Practical integration and selection guidance

This indexable insert is part of an ISO-compliant system that requires a matching holder, correct clearance, and the appropriate clamping set and screws for reliable operation. Selection of the right chipbreaker and grade should be based on workpiece material, depth of cut and machine-tool rigidity. For customers seeking to optimise cycle times or to integrate the insert into existing tool assemblies, the technical team can advise on holder compatibility, tolerance classes and the most suitable cutter geometry for the application.
