Abstract (en)
A combination chuck (32) is provided which makes it possible to transmit both a traction force to the end of a rod (48) and a torque (moment of rotation) to a drill (46) on a machine (10) for drilling a taphole. This combination chuck comprises a rotary body (34) mounted on the drive spindle (26) of a work member (18) which can slide on the drilling machine (10). A support structure (36) integral with the work member (18) forms a guide cage around the rotary body (34). Means for transmitting a traction force to the end of a rod (48) and a torque to a drill are arranged around a front cavity in the rotary body (34). <IMAGE>
