Carbon fiber aluminum composites are included in the fuselage wings, flaps, horizontal and vertical tailfins and many other parts of the new generation of aircraft. In aircraft assembly,Large numbers of holes are required for the assembly of these components, and they are processed with PCD countersinks。

LINKUT PCD Countersinks have the following characteristics：
1. The matrix is made of high strength alloy steel, heat treatment HRC45-50.

2. PCD cutting edge high durability, reduce the replacement time, improve processing efficiency.

3. Longer guide column life, tool life increased by 200%.

4. High precision grade thread and cone match, quick and easy to replace drill bit.

5. The surface roughness can reach Ra0.4, excellent retention.

6. Each Angle size can be customized.
