The tool includes a base including a rigid carrier and a flexible collar encircling the rigid carrier; an elastically compressible interface; and a flexible buffer including a central portion that is located in line with the rigid carrier and a peripheral portion that is located transversely therebeyond. This peripheral portion is connected to the carrier exclusively via the interface and via the collar, wherein the collar is configured so that the tool is elastically deformable between a rest position that it adopts in the absence of stress and a reference position in which the transverse end second surface of the flexible buffer is pressed against a reference surface that is spherical and of radius included between 40 mm and 1500 mm.
