DCMT 11T308 AH120 indexable turning insert – PVD-coated carbide, 55° rhomboid – Tungaloy

The DCMT 11T308 AH120 is an ISO-standard indexable insert designed for precision external and internal turning where a sharp cutting edge and consistent process security are required.

• PVD-coated carbide grade AH120
• 55° rhomboid geometry for versatile turning
• 0.8 mm corner radius for consistent edge life
• Cylindrical hole with single-sided countersink

Predictable performance through sharp geometry and process security

The rhomboid 55° geometry and defined 0.8 mm corner radius give the insert a predictable cutting behaviour that supports stable chip formation in a wide range of turning tasks. The shape is optimised for both external and internal operations, enabling reliable entry and exit performance and reducing vibration risk in stable set-ups. The result is improved dimensional consistency and fewer reworks in serial production, which supports continuous, efficient machining.

Adaptable turning capability with ISO-standard compatibility

Designed as part of an ISO-series system, the insert matches holders by form, relief angle, tolerance class, fastening, size and thickness. The 7° relief angle and the ISO code 11T308 indicate the standardized seat and clamping requirements; this simplifies tool selection and replacement. When used with a correctly specified holder and clamp set, the insert provides consistent seating accuracy and repeatable positioning, crucial for batch runs and interchangeable tool systems.

Wear resistance and tool life from a PVD-coated carbide grade

The AH120 grade is a PVD-coated carbide engineered for wear and chipping resistance while maintaining a sharp cutting edge. The coating enhances heat resistance and reduces adhesive wear at elevated cutting temperatures, extending useful life under mixed cutting conditions. In practice, this means longer intervals between indexings and less downtime for tool changes — a direct contribution to higher productive uptime and lower unit costs over time.

Practical features that support assembly and stability

The insert is supplied with a cylindrical centre hole plus a one-sided countersink (40°–60°), facilitating robust clamping and simple alignment during tool assembly. The 3.97 mm thickness and 11 mm nominal size pair with standard DCMT holders to ensure stable clamping and predictable engagement. The single-sided chipbreaker design should be selected according to workpiece material and machining stability to optimise chip control and surface finish for each application.
