Various manual, semi-automatic or fully automatic tools and machines which have different capacities are used for drilling operations in furniture, joinery, wooden and wood building industries. These show significant structural and functional changes based on traditional and advanced technologies. Especially in the last quarter of the 20th century, the use of CNC machines in the processing of wood and wood-based materials provided significant possibilities in production elasticity and capacity. These have high dimensional sensitivity and surface quality processing technology from the simplest to the most complex product geometries. Although CNC machines have advanced technologies, the interactions between cutting tools, machining conditions and materials have an important place in the machining of wood and wood-based materials for a good surface quality. Parameters of machining conditions are presented in a wide range with technical data, equations and graphics associated with surface quality for both traditional and modern machines. However, in practice, the machining conditions are usually based on the feed rate, rotation speed, grain direction, cutting width and material type according to cutter characteristics. In this study, it is focused on drilling bits and machines used in furniture industry. Problems and proposed solutions encountered with drilling operations were indicated.
