ABSTRACT:
In a chuck for clamping a tool (1) into a carrier (2), a shank (3) is provided in the tool (1) and a mating bore (4) in the carrier (2). The shank (3) is insertable into the mating bore (4) and can be fixed there. To fix it, a locking element (7) is displaceably mounted in a radial transverse recess (6) of the shank (3) and its two front ends are provided with planar slopes (9, 10). Both slopes (9, 10) form an acute angle (11) which closes in the direction toward the tool (1). The chuck is tightened by means of pressure screws (15) which are screwed radially into an annular flange (12) of carrier (2) surrounding bore (4). The pressure element of the pressure screws (15) is a ball (14) having a truncation surface (13) which, when positioned in the same plane, charges the opposing slope (9, 10) of the locking element (7).
