Slim shrink chuck is used for induction shrinking of carbide tools. Due to the slim shape of this new chuck, interfering edges are a thing of the past. The external geometry of the new shrink chuck TSF is designed with a 3° incline, compatible with dies and moulds. The slim shrink chucks have a non-corroding coating. The chucks have a concentricity of <0003mm and are fine balanced at <1gmm/kg. Specifically for these slim chucks, all new ThermoGrip® shrink units are programmed with the parameters of heating time and generator output to shrink all possible shank diameters.
