摘要： A chuck with key tightening, for a machine such as an electric drilling machine, comprising gripping means for gripping a tool such as jaws, which are guided in a translatory movement in grooves which are inclined with respect to the longitudinal axis of the chuck and which are machined in the chuck body, the chuck being characterized in that it comprises a toothed ring to which a tightening nut is connected, the nut cooperating with the threads of the gripping means, the toothed ring being provided in the region of its teeth with at least one retaining region whose internal diameter is smaller than the external diameter of the tightening nut, at least one component or at least one group of components having the same function, movable with respect to the chuck body, that is to say, the jaws and/or the nut and/or the toothed ring, being of sintered metal. The chuck is particularly advantageous for use on a percussion drilling machine, if desired, because the features of construction prevent its components from becoming disconnected.
