  • the holder can consist of one piece with the part that carries the rotary head. So that when using the multi-jaw chuck with drills that have no axially continuous channel, the suction nozzle does not interfere, it can be provided in a particularly advantageous embodiment of the invention that the suction nozzle is easily detachably connected to the rotary head, preferably by a snap lock, in particular thereby that the suction nozzle is designed as a plug-in part engaging in a radial bore of the rotary head. But it can also be provided that the holder of the multi-jaw chuck consists of a front and a rear part, which are connected by a screw connection, and that the rear part carries the rotary head.
  • a best preferred design of the multi-jaw chuck according to the invention is achieved in that the coaxial outer surface is at least partially cylindrical and that the cylindrical outer surface is provided with a circumferential annular groove into which the outer end of the bore opens, and that as a rotary head one on the cylindrical
  • External surface rotatably mounted sleeve is provided.

  • an O-ring 33 is arranged to form a snap closure on the engaging in the bore 29 end of the suction port 32 in an annular groove surrounding this end, which engages behind the inner edge of the bore 29 when the end 31 of the Suction nozzle 32 engages in the radial bore 29.
  • This end 31 is dimensioned so that it extends together with the O-ring 33 approximately over the entire width of the annular groove 29, so that the end 31 of the suction nozzle engages in the bore 29 and thus simultaneously in the annular groove 25 32 the sleeve 29 is secured against axia les displacement on the rear part 18 or 18 'of the holder 11.
  • the suction nozzle 32 has a collar 34, by means of which the suction nozzle abuts the sleeve 28 from the outside when it engages in the bore 29.

  • the present invention is intended for use with drills 14 having an axially continuous suction channel 37. Characterized in that the axial bore 27 of the holder 11 in the Support surface of the drill 14 opens into the floor 15, the bore 27 continues the suction channel 37 of the drill when the drill 14 is inserted.

If the suction hose 36 is now connected to the suction nozzle of a vacuum cleaner, then when drilling the drilling machine 23, the drilling dust can be removed directly from the
  • Ear point can be suctioned through the suction channel 37 by the vacuum cleaner. Since here the sleeve 28 forms a rotary head with the suction nozzle 32, which is not taken along when the spindle 22 and thus the holder 11 are rotated, this extraction of the drilling dust from the drilling point is always possible. Due to the displaceable connection of the suction hose 36 to the suction nozzle 32, air can always be let in through the ventilation opening 40 if necessary, in order to avoid overloading the vacuum cleaner motor.
  • the suction nozzle 32 in the exemplary embodiments shown in FIGS. 1 and 1a is designed as a plug-in part, that of the through the sleeve 28 formed turret can be solved by simply pulling, so that the then unnecessary suction port 32 does not interfere.
