A grinding device comprising a motor (2) driven drive shaft (4) projecting from a housing (1). The drive shaft (4) passes through a bearing unit (5). A tool receptacle (8) is provided at a free end (7) of the drive shaft (4) for removably attaching a tool (9), in particular a grinding wheel. A suction hood (11) abuts the housing (1) and encloses the free end (7) of the drive shaft (4). The suction hood (11) comprises a suction space (12) opening in a direction facing the tool receptacle (8) side. The suction space (12) has a separator wall (13) between the tool receptacle (8) and the bearing unit (5) to prevent contamination of the bearing unit (5). The wall divides the suction space (12) into a dirty space (14) that opens facing the tool receptacle (8) and an adjacent driver space (15) that opens to the opposing side.
