Drilling into carbon fiber reinforced plastic (CFRP) with conventional tools often results in defects like delamination, fiber pull-out, etc. In order to achieve high-quality machining of CFRP, this study newly developed a woven metal wire tool with electrodeposited diamond grains. A hole of 20 mm in diameter was drilled using the developed tool with hyper grinding, which supplies a coolant through the grinding wheel at the grinding point. As a result, this method made a good hole without delamination at the entry and exit of the hole. In addition, an excellent surface roughness of 0.64 μm Ra was achieved.
