DCMT 11T308 AH8005 DCMT turning insert by Tungaloy — PVD‑coated carbide, 55° rhombic

DCMT 11T308 AH8005 is a rhombic ISO turning insert designed for external and internal turning of demanding materials, offering robust chip control and high wear resistance in stable cutting conditions.

• PVD‑coated carbide AH8005
• Rhombic 55° geometry
• 0.8 mm corner radius
• Cylindrical hole with 40°–60° countersink

Precise geometry and consistent compatibility for turning applications

The DCMT11T308 insert brings together a defined 55° approach angle and a rhombic form to deliver repeatable engagement in a wide range of turning tasks. The ISO‑standard geometry ensures compatibility with matching external holders and boring bars, where fit depends on form, clearance angle, tolerance class, fixation and plate thickness. With a PVD‑coated carbide body the component offers predictable wear behaviour, which makes tool change intervals easier to plan and reduces unexpected downtime.

Durable grade and chip control for hard and heat‑resistant materials

The AH8005 wear‑resistant grade is optimised for machining heat‑resistant alloys and other hard materials under stable cutting conditions. The single‑sided chipbreaker promotes controlled chip formation and evacuation, improving surface finish and lowering the risk of rework. Together, the coating and substrate support higher cutting speeds and extended tool life compared with uncoated alternatives, delivering a clear efficiency advantage on demanding workpieces.

Practical mounting details and selection guidance to increase productivity

With a 0.8 mm corner radius and an insert thickness of 3.97 mm, this rhombic plate suits operations where a balance between edge strength and form accuracy is required. The plate features a cylindrical hole with a one‑sided countersink (40°–60°) for secure clamping and precise seat location. Choose the chipbreaker and grade to match workpiece material, machining type and machine stability; for further specification matching, Metav Werkzeuge can provide technical consultation and cutting data to ensure optimal setup and repeatable results.

FAQ

What materials is this insert suitable for?
The DCMT11T308 AH8005 Tungaloy insert is designed primarily for heat‑resistant alloys and other hard materials where a wear‑resistant PVD‑coated carbide grade is required.

Can this insert be used for both external and internal turning?
Yes, the rhombic shape and ISO‑standard geometry allow use in both external turning and appropriate internal applications when fitted to a matching holder or boring bar.

How does the AH8005 grade affect machining performance?
AH8005 provides enhanced wear resistance and thermal stability, which helps maintain edge life and surface quality during extended cuts in demanding materials.

What clamping features does the plate have?
The plate is supplied with a cylindrical hole and a one‑sided countersink (40°–60°) to ensure reliable clamping and precise seating in compatible toolholders.

Is the 0.8 mm corner radius suitable for finishing passes?
A 0.8 mm corner radius offers a compromise between edge strength and the ability to achieve fine surface finishes; select a smaller or larger radius depending on the required surface specification and load.
