<p>The chuck (1) includes a receiving sleeve (3) having a guide surface (12) extending along a longitudinal axis with a radial dimension (R), and at least three, axially extending, up to a free end surface of the chuck, entraining grooves (5) located in front of the guide surface. The entraining grooves are arranged radially outside of the radial dimension at angles of 0, 120, and 240 degrees and each having a central angle defined with respect to the radial dimension and amounting to at least 40 degrees. At least one locking member (5) is radially displaceable over the radial dimension and arranged between two circumferentially adjacent entraining grooves and diametrically opposite a third entraining groove.</p> |
