<p>The drilling chuck with jaw for hand drill can be used with a drill (14) presenting an axial traversing channel (37) allowing the aspiration of the chips produced by the drilling. A rotary head (28) is arranged on the chuck carrier (11) forming with it an annular space connected, on one hand, through holes (26, 27) arranged in the carrier, to the drill (14) channel (37) and, on the other hand, through a coupling sleeve (32), to an aspiration conduit (36). </p> |
