摘要：
A compact drilling system capable of improving working efficiency. The drilling system includes a drilling machine and a compressor. A control circuit controls performances of a drill motor in the drilling machine and an air compression motor in the compressor based on the detection result of a pressure sensor that detects a pressure within an air tank provided in the compressor. When one of the motors is activated, the other motor is not allowed to be operated and only when the drill motor is activated, compressed air is supplied from the air tank to the drilling machine. An electrical socket is provided in the compressor. A power cord extending from the drilling machine can be connected to the socket.
