Claim 0:
1. A tool for the application of liquid agent on a mantle surface of a circular-cylindrical object, comprising a tool head having an axial through hole with a substantially circular cross-section, which tool head comprises:
an inner flange where the through hole in at least one axial position is delimited by an application surface, having an application radius, for guiding the tool along the object to be coated;
an outer flange extending axially after the inner flange on a radial distance from the center of the hole which is greater than the application radius; and
a distribution chamber running around the inner flange and comprising at least one outlet at an inner end edge of the inner flange, which leads out to the through hole where the outer flange extends axially after the inner flange, and which at least one outlet is distributed around the through hole;
at least one injection pipe to the distribution chamber in order to be able to supply liquid agent to the distribution chamber;
wherein an asymmetrical restriction is provided at the at least one outlet so that the at least one outlet is restricted where the pressure is the highest.
