A column positioning device for a drill press includes a base having a post and a positioning pin respectively extending from a top of the base. The post is received in a hollow column on which a motor is connected. The column has two positioning passages so that the positioning pin is engaged one of the positioning passages. A frame is connected a side of the column and a pusher is connected to the frame. A rod extends from the pusher and a pressing member is movably mounted to the rod. When rotating the column 180 degrees about the post, the column is conveniently positioned by inserting the pin with the other positioning passage.
