Abstract: A device for positioning a part to be cut placed on the bed of a cutting machine has an angular positioner provided, on the one hand, with means for sliding in a plane parallel to the plane of said bed and in a translational guidance direction parallel to the cutting plane of a cutting tool of said cutting machine, and, on the other hand, with means for positioning the part to be cut relative to said plane of said cutting tool in a plurality of special, defined angular positions.

Abstract: A manual appliance for cutting tiles, has a carriage (4) which slides above a base (1) which receives a tile to be cut. The carriage (4) has a cutting wheel (19) and a breaking head (23). The breaking head (23) is able to respond to a control means (34), in order to adopt either an idle retracted position so that the wheel comes into contact with and score the tile placed on the base (1), or, a working position in which only the breaking member comes into contact with the top face of the tile. The carriage has a handle (21) for exerting a bearing force on the wheel (19) when it scores the tile, and a bearing force on only breaking member (23) when it is in its working position.
