Abstract: A tool for surface smoothing machines, includes a substantially plane support, provided at one side with a coupling for fitting to a smoothing machine, and at the opposite side with a housing that protrudes relative to the plane; a housing for an abrasive member, provided on a body protruding from the support and provided with an external raised edge; a layer made of deformable material inserted into the housing containing a sector of abrasive material inserted into said housing. These features prevent the same support from coming into contact with the surface to be polished when the tool is worn, which may therefore damage the surface itself. The wedge shape is such that in each portion, the sector exhibits a rest surface that is proportional to the speed at which it moves onto the surface to be polished, so as to obtain a perfectly even wear of the entire tool.
