Zusammenfassung:	The invention belongs to the technical field of architecture accessory attachment and particularly relates to a self-localization spitting drill. The self-localization spitting drill is characterizedin that the self-localization spitting drill comprises a screw cap, a screw connected to the screw cap, an inner groove formed in the inner side of the cap of the screw, a screw-in depth control section arranged on the front end of the screw, a self-tapping screw thread section arranged on the middle section of the screw, a self-drilling screw tail arranged on the rear section of the screw, and ascrew thread transition section arranged between the screw-in depth control section and the self-tapping screw thread section and located at the end of the screw-in depth control section. The screw-indepth control section and the screw thread transition section are arranged on the front of the self-tapping screw thread section on the screw, so that the screw-in depth of the screw is effectively controlled, the installation
