The present invention relates to a drilling having a drilling spindle and a drilling chuck, which has a chuck body having clamping jaws adjustable in relation to the chuck axis and having a spindle receiver for the coupling with the drilling spindle. Centering surfaces, which come to rest on one another in the mounted state, are implemented in the spindle receiver and on the drilling spindle, a bayonet ring, having at least one journal pointing radially inward, is mounted so it is rotatable on the chuck body on its side facing toward the drilling spindle, at least one axially oriented journal receiver having an undercut around the circumference is implemented in the drilling spindle, and a cam receiver is provided on the rear axial end of the chuck body facing toward the drilling spindle for rotationally-locked receiving of a cam implemented on the drilling spindle.
