A control device for a drill device with an electromagnetic base equipped with a direct current feed motor that moves forward and backward, comprising: a drilling completion detection means for detecting completion of drilling of a workpiece by the electric drill; and an output of the drilling completion detection means. a feed motor reversing means for changing the polarity of the voltage applied to the feed motor and applying a voltage higher than the voltage applied to the feed motor during drilling to the feed motor; An electromagnetic base comprising a safety circuit that detects that a voltage higher than the voltage applied to the feed motor is applied to the feed motor and stops power supply to the drill motor and the feed motor. Control device for attached drill equipment. (2) The safety circuit consists of a relay, a resistor, and a diode connected in series, each having a contact that stops the supply of power to the drill motor and the feed motor, and which is connected in series to the relay to stop the supply of power to the drill motor and feed motor. 2. The control device for a drill device with an electromagnetic base according to claim 1, wherein the control device is connected in parallel with the feed motor so as to perform the following operations. (3) The drilling end detection means is a means for detecting that the current value of the drill motor exceeds a predetermined value and falls below the predetermined value after a scheduled time elapses. Control device for drilling equipment with electromagnetic base.
