A drill for an implant surgery is provided which allows a mucous membrane in the maxillary sinus to be quickly and safely lifted without being damaged during a surgery for the maxillary sinus. The drill for use in an implant surgery includes a connection portion formed at an upper end of a body of the drill to be connected with a driving device; and a cutting portion formed at a lower end of the body and having a cutting blade for drilling, wherein an outer circumferential edge of a distal end of the cutting portion protrudes rather than a center of the distal end of the cutting portion.
