A dust bag used multiple times is provided to prevent dust resulting from drill vibration form scattering by forming drill insertion parts and to increase general purpose usability by changing the position of an adhesive fixing device after using the adhesive fixing device. A dust removing bag used multiple times comprises an envelope part(110), insertion parts(120), and an adhesive fixing part(130). The envelope part is formed with a space expansion part(113) to expand spaces to two sides of an envelope body(111) sealing the outer side to a sealing part(114). The insertion parts have insertion holes(121) communicated with dust storage spaces and insertion cut parts(122) for preventing the dust from being discharged. The adhesive fixing part is used many times by changing the position of the adhesive fixing part after removing a rear paper by attaching one side of an adhesive fixing device(131) having an adhesive part(132) to an envelope body and attaching the rear paper to the other side of the adhesive fixing device.
