摘要： A tool holder and an associated tool with the shank are provided for a drilling and/or striking machine tool. The tool holder has a drive spindle with a receiving opening provided with a cone for centering and a portion for driving the tool. Dumbbell-shaped locking elements are guided with their inner ends in a passage and with their outer ends in a longitudinal groove. The outer ends engage in pockets in an axially displacable locking sleeve which is prestressed by a spring in the direction toward its locking position.
