Description
Die Erfindung hat din Bohrfutter mit auswechselbaren Spannbacken zum Gegenstand, bei dem die Spannbacken durch -einen dieselben umfassenden Ring zu einen einheitliehen Ganzen vereinigt wenden.The subject of the invention is the drill chuck with interchangeable clamping jaws, in which the clamping jaws by -a ring encompassing the same to one unit Turn the whole thing together.
Die bisher bekannten Bohrfutter haben den Nachteil, daß sie beim Auseinandernehmen· in ihre Einzelteile zerfallen und es kaum zu vermeiden ist, Einzelteile, d. h.
