摘要： The invention relates to a drill chuck which has a drilling needle receptacle device for removable receiving of a drilling needle (1), a hollow cylindrical magnetic holder for the drilling needle receptacle device and a coupling device for torque transfer from a drive device to the drilling needle receptacle device. The drilling needle receptacle device, in which a drilling needle (1) having a flattened end section (1') can be received, has a receptacle element (7), at least two clamping bodies (10) and a clamping insert (6). The receptacle element (7) has at least one cylindrical section (72) having a recess (71) and the clamping insert (6) has counter-molded bodies (61) which supplement the clamping bodies (10) and which extend away from a stop disc (62). The stop disc (62) contacts a face of the cylindrical section (72) and has a lead-through opening (63) for the drilling needle (1). The counter-molded body (61) and the clamping bodies (10) are designed in respect of the dimensions and shape thereof for arrangement in the recess (71) and for clamping receiving of the flattened end section (1') of the drilling needle (1) between the clamping bodies (10) and the counter-molded bodies (61). The invention further relates to a drilling needle and to a drilling needle-drill chuck assembly.
