Abstract

A thermal shrink fit chuck for a high performance rotary tool, e. g. drill, milling machine etc., has an integral duct for supplying cooling fluid to the tool. The socket for the tool shank is provided with drainage ducts to prevent cooling fluid collecting in the chuck and thereby generating high pressure steam when the chuck is heated when replacing the tool. The drainage ducts drain collected fluid back into the cooling fluid supply duct and prevent.
