Abstract (en)

[origin: US5704744A] An arrangement for transmitting torque from a chuck (5) in a manually operated tool to a tool bit (1) having an axially extending chuck section (2) insertible into the chuck. The chuck section (2) has axially extending entrainment faces (31) arranged to cooperate with correspondingly shaped torque transmitting faces (6) in the chuck (5). The chuck section (2) is arranged to cooperate with a device (7) in the chuck for retaining the tool bit and affording limited axial displaceability of the bit. The chuck section (2) is formed with at least one recess (4). The device (7) in the chuck includes a locking element (8) engageable in the recess. The locking element (8) is axially and radially displaceable both to a limited extent and the axial displaceability of the tool bit is possible at least in part, by the limited axial displaceability of the locking element (8).
