DCMT11T304 AH8015 – ISO rhombic turning insert, PVD-coated carbide by Tungaloy

The DCMT11T304 AH8015 is an ISO rhombic turning insert designed for general external and internal turning, especially suited to heat-resistant alloys.

• ISO rhombic insert DCMT11T304, 55° cutting angle
• PVD-coated carbide grade AH8015 for hot alloys
• 0.4 mm corner radius for precise finishes
• One-sided chipbreaker for controlled chips
• Countersunk hole for secure clamping

Consistent tool life through a balanced carbide grade

The combination of PVD coating and a wear-resistant carbide substrate in grade AH8015 delivers a balanced trade-off between abrasion resistance and edge stability. This balance reduces unplanned tool changes and contributes to a more predictable process where indexable inserts are part of a production cycle. The coating enhances heat resistance during elevated cutting temperatures, making the insert suitable for machining heat-resistant and high-temperature alloys while maintaining surface quality and extended edge life.

Geometry engineered for precision and secure clamping

A 55° rhombic geometry with a 0.4 mm corner radius is optimised for accurate finishing and repeatable dimensional control in turning operations. The plate thickness of 3.97 mm and the integrated countersunk hole (cylindrical hole with a single-sided countersink at 40°–60°) ensure secure clamping and stable seat engagement in ISO-standard toolholders. Correct matching of holder form, clearance angle, tolerance class and fastening hardware preserves the insert’s positional accuracy and reduces chatter, thus improving surface finish and tolerance adherence.

Controlled chip flow and versatile application scope

A one-sided chipbreaker provides reliable chip control for a wide range of feeds and depths of cut, simplifying post-process handling and reducing the risk of chip entanglement in automated centres. The insert is part of an ISO-indexable system that typically includes a compatible external holder or boring bar, a shim/clamping set and replacement screws, enabling straightforward integration into established turning setups. Its intended application is general turning of heat-resistant alloys and similar demanding materials where a mix of process security and economy is required.
