DCMT11T304 AH8015 indexable turning insert — PVD-coated carbide, rhombic 55° geometry, Tungaloy

A DCMT11T304 AH8015 indexable insert engineered for efficient external and internal turning of heat-resistant alloys, offering a balanced compromise between wear resistance and edge stability.

• DCMT11T304 ISO turning insert by Tungaloy
• PVD-coated carbide grade AH8015
• Rhombic 55° geometry with 7° clearance
• Single-sided chipbreaker and 0.4 mm radius

High-performance grade for heat-resistant alloys

The AH8015 grade is a PVD-coated carbide developed as a first-choice solution for general machining of heat-resistant alloys, combining wear resistance with reliable cutting-edge stability. The coating process increases resistance to temperature-related abrasion, which preserves the cutting edge during higher cutting speeds. Conformity with ISO geometry ensures interchangeability within standard tool systems; compatibility with a holder is determined by form, clearance, tolerance class, fastening, size and thickness and should be checked before assembly.

Geometry and chip control that improve surface finish

A rhombic 55° insert angle, together with a 7° clearance, delivers favourable cutting forces and access to narrow features, while the single-sided chipbreaker promotes controlled chip formation under a range of cutting conditions. The 0.4 mm corner radius reduces edge chipping in interrupted cuts and supports consistent surface quality on both external and internal profiles. These geometry choices translate into fewer reworks and more predictable finishing results for demanding components.

Clear mounting specification for efficient set-up

The insert is supplied with a cylindrical fixing hole and a one-sided countersink (40°–60°), enabling secure and repeatable clamping in compatible holders. The plate thickness of 3.97 mm and plate size of 11 mm correspond to common ISO holders, simplifying stock management in production environments. The tool system comprises the indexable insert, the appropriate external holder or boring bar, a support/clamping kit and spare screws, which together form a stable assembly tailored to the selected application.

Long tool life through balanced material and design

Combining a robust cemented carbide substrate with a modern PVD finish, this insert is designed for consistent tool life and economical productivity in serial production. The grade’s balance between toughness and hardness helps to avoid premature flank wear while maintaining a stable cutting edge. Choosing the correct chipbreaker and grade in relation to workpiece stability and machining method will extend service intervals and reduce tooling costs per component.

FAQ

What materials is this insert suited for? The AH8015 grade insert is intended primarily for heat-resistant alloys; the DCMT11T304 AH8015 performs well where a balance of wear resistance and edge stability is required.

Is the insert compatible with standard ISO holders? Yes, the geometry conforms to ISO indexable insert standards and can be used with compatible holders that match form, clearance, tolerance, fastening, size and thickness.

How does the chipbreaker affect machining? The single-sided chipbreaker on this insert promotes controlled chip formation and can improve surface finish and swarf evacuation when matched to the workpiece and machining parameters.

What are the mounting details for the insert? The insert is supplied with a cylindrical fixing hole and a one-sided countersink (40°–60°) and requires a holder that accommodates this fixing style for secure clamping.

Can the radius be used for finishing? The 0.4 mm corner radius offers a compromise between strength and finishing capability, making it suitable for many semi-finish and finish turning operations.
