An injector device (5) connected to the driver (7) supplies a liquid from a reservoir to a conduit (11) inside the tool. The conduit has a cross-section greater than that of the steel wire (3) for driving the brush (10). A spray nozzle (25) connected to the brush is also connected to the injector device via the conduit. The wire is rotated relative to a casing (1) around it and has one end connected to the rotary driver. The other end of the wire is connected to a brush. |
