Abstract

A vibration damped hand held rotary grinding machine comprising a housing (10), a rotation motor (11), an output shaft (13) drivingly coupled to the motor and having mounting means (14) for attachment of a grinding wheel (15), two handles (17, 18) rigidly mounted on the housing (10) and extending in right angles relative to the output shaft (13) as well as to each other, and a sector-shaped non-resilient safe guard (19) which is rigidly attached to the housing (10) and surrounding partially the grinding wheel (15) and which has an arc-shaped rim portion (20) encircling partially the grinding wheel circumference. Vibration damping inertia elements (22, 23, 24) are rigidly attached to the safe guard (19) rim portion (20) and to the outer extremities of the handles (17, 18) such that the moment of inertia of the machine is substantially increased as is the vibration force absorption. <IMAGE>
