Abstract

An arrangement for producing grooves in walls, ceilings and the like with the use of a hand-held processing machine, has a rotatable material-removing tool driven in rotation by the machine, and a housing surrounding the tool. The housing has a guiding piece through which the tool extends. The guiding piece has a guiding surface which is adapted to lie on the surface of the wall, ceiling and the like, and is inclined at an acute angle relative to the axis of the tool. The guiding piece is detachably mounted on the processing machine.
