    摘要: A chuck for a percussively driven working tool includes at least one radially displaceable, locking member (3) and a locking element (5, 6) for blocking radial displacement the at least one locking member outwardly. The locking member has a locking surface (4) located radially adjacent to the at least one locking member (3) and formed as a radially damping surface.

    摘要: A drilling and/or chiseling tool (1) comprises a shaft (2) and a cylindrical insertion end (4) connected with the shaft (2) with at least one elongated recess (5 to 8), open toward the outer surface of and toward the free end of the insertion end (9) and forming a rotationally locking groove. A collar (3) is disposed between the shaft (2) and the insertion end (4) and extends at least partially around the tool (1) and projects at least radially outwardly of the shaft (2) and of the insertion end (4). The cylindrical insertion end (4)has a diameter not less than 18 mm and preferably larger than 22 mm. The at least one recess (5 to 8) has a cross-sectional area, extending perpendicularly to the axis of the tool (1), and expands toward the outer surface and is provided essentially in the form of an arc of a circle. A tool chuck of a drilling and/or chiseling device, matched to the insertion end, is provided to receive the insertion end (4) of the tool (1) and fit rotationally locking bodies into the at least one elongated recess (5to 8).
