Abstract
The invention relates to a tool holder () for shrink-fit attachment of rotating tools () with predominantly cylindrical shafts (), having a chuck () with a clamping section () containing a conical receiving bore () to accommodate an insert () that has a cylindrical bore () to accommodate the tool shaft () and has a conical outer surface () to be contained in the receiving bore () of the clamping section (). The insert () is embodied so that after the axial insertion of the insert () into the hot chuck (), a contact is produced between the insert () and the chuck () on the one hand and between the insert () and the inserted tool shaft () on the other hand and, when the chuck () cools, the tool shaft () is clamped, wherein it is possible to bridge over large diameter tolerances while achieving maximum clamping forces ().
