<p>The tool has at least one tooth (20) projecting at a distance from its axis of rotation, and a counter-tooth (30) in front of it to act as a breaker for the chippings produced during milling. The countertooth is in the shape of a flange lying parallel to the front face (22) of the tooth, and has an outer edge of similar height to the tooth or slightly below it. The counter-tooth has an aperture (34) through it and is set at a distance of between 2.5 and 3.5 mm from the milling tooth. The tooth's outer edge is curved in shape, with a semi-circular central section, and the hole in the counter-tooth is circular and has a diameter of 5.5 mm in the flange's rear face.</p> |
