The invention discloses a multi-angle universal type drilling tool used for stones. The multi-angle universal type drilling tool comprises an operating table, a positioning column, a positioning plate, a motor, a drill bit and a control box. The multi-angle universal type drilling tool is characterized in that the operating table is arranged on a bracket; a positioning slot is formed in the operating table; the positioning column is perpendicularly arranged on the operating table; a positioning block is arranged on the positioning column; the motor is arranged on the positioning plate; the drill bit is connected with the motor through a mounting block; and the control box is arranged on the bracket. According to the multi-angle universal type drilling tool used for stones disclosed by the invention, a wax layer is arranged in the positioning slot, so that to-be-drilled stones are firmly fixedly arranged on the wax layer, and stability, in a drilling process, of the stones is improved, and therefore, drilling quality of the stones is improved; and the positioning plate is set to be a structure capable of rotating on the positioning block by a connecting screw rod, so that the drill bit can carry out drilling on the stones in a multi-angle mode, and therefore, application scope of the drilling tool is expanded, and cost of manufacturing a plurality of drilling tools is reduced.
