The device for deburring and bevelling (inner and outer) drilled bores is provided with a casing and a drive shaft extending therefrom as well as with an arm carrying a deburring and bevelling tool as well as with a toothed belt to drive the tool, thereby making possible and facilitating a modification and an adaptation of the arm length, therefore being of universal use. The device is characterized in that the armn (27) is removably held in the casing (3) by means of grooves (33) and rails (31) and in that it is spring biased (29), the compression of the spring tensioning the toothed belt (21). A set of arms (27) of different lengths with corresponding toothed belts (21) is provided. The tool (45) may also be changed, being an element of a tool changing set.
