An accessory is intended for a hand drilling machine (3). The machine has in the common way an output shaft and a cylindric attachment surface (2) located near the output shaft. The accessory includes a roller (35) having a replaceable working surface material (69). The roller is at its two ends rotatably mounted in outermost ends of a fork-shaped unit formed by a transmission unit (17) and an angular part (25) which can be secured (29) along a portion (23) of the transmission unit. The transmission unit is rigidly connected to a mounting part (1) which is intended to mount the accessory to the attachment surface of the driving machine and which encloses a coupling between the output shaft of the machine and the input shaft of the accessory. To the mounting part a handle (9) is mounted in a selectable position. In or at the fork-shaped unit a transmission for transferring the rotary movement from the coupling to the roller is provided. The accessory can be used for various types of cleaning, brushing, grinding and polishing jobs. A prolongation part can be easily inserted between the driving machine and the mounting part.
