Abstract: Despite the facts that carbon fiber reinforced plastics (CFRP) components are mostly produced near net shape, machining, especially drilling is often required in order to bring the component into dimensional requirements and prepare it for assembly. Rapid drill wear and serious machining defects are the key problems in CFRP drilling, and employing proper drill is an effective way to solve these problems. In this paper, tests of the brazed diamond core drill are presented and the related issues, such as the thrust force, the drilling quality and the drill wear are studied.
