The invention provides a novel wooden plug taking cutter drill bit which comprises a columned drilling handle and a drilling body. One end of the drilling body is fixedly connected with the drilling handle, a drill bit body is arranged at the other end of the drilling body, a through hole is formed inside the drilling body, and a groove is formed in the middle portion of the drilling body and is communicated with the through hole; and the drill bit body is a hollow circular cone table with the smooth surface, a notch is formed in the drill bit body, the two sides of the notch of the drill bit body are each provided with cutting edges of symmetrical structures, the depth of the groove is not smaller than the external radius of the drilling body, and the notch in the drill bit body is smaller than 3/4 arc. Compared with the prior art, the double cutting edges which are symmetrical and are of same structures are arranged on the drill bit body of one driving body, and therefore the two cutting edges can be combined to be used on one drilling handle, after one end of the drilling body is ground to be blunt, the other end can be used for grinding, and the suing economical efficiency of the drilling body can be improved.
