摘要

The quick-change chuck (1) has several primary torque transmitting flanks (14) having torque transfer portion (13) for torque-transmitting engagement with one or more torque introduction flanks (21) of a screwdriver bit (17) which comprise drive shaft (19) with primary drive profile. Several secondary torque transmitting flanks (16) have torque transfer portion (15) for torque-transmitting engagement with torque introduction flanks (26) of screwdriver bit (22) which comprises drive shaft (24) with secondary drive profile. The torque transfer portions are spaced apart from each other.
