Drilling stop

A drilling stop for a drilling tool;

• comprising:
• a shaft having an axis of symmetry and an outer surface, wherein at least a part of the outer surface has a stop-1 geometry, and with a stop-sleeve having a longitudinal axis, which can be placed and moved axially on the shaft, wherein as an additional component a stop-element with a center axis, a locking-3 geometry and a stop-3 geometry is provided, which can be moved in the axial direction relative to the axis of symmetry on the shaft by axial positive or frictional locking brought into engagement with the stop-1 geometry and can be adjusted in the axial direction independently of the stop sleeve and against which the stop-sleeve can be placed at least indirectly in the axial direction for the purpose of limiting a drilling depth T,
• wherein the stop-element has a locking-3 geometry and that the shaft has a holding-1 geometry with respect to the axis of symmetry, wherein
• a) the stop-sleeve has a locking-2 geometry on the end face, which can be brought into operative contact with the locking-3 geometry in order to fix the stop-element in the circumferential direction relative to the axis of symmetry, the stop-sleeve having a holding-2 geometry, which can be brought into a form or force closure in the circumferential direction with the holding-1 geometry of the shaft, or
• b) as an additional component a locking-part is provided which has a holding-4 geometry which can be brought into a form or force closure in the circumferential direction with the holding-1 geometry of the shaft, wherein the locking-part has a locking-4 geometry which can be brought into operative contact with the locking-3 geometry in order to fix the stop-element in the circumferential direction relative to the axis of symmetry on the shaft, wherein the stop-sleeve can be placed against the locking-part in the axial direction, or
• c) wherein the stop-1 geometry is designed as a recess and the stop-3 geometry is designed as a movable pawl, the pawl placed in the recess forming a form closure between the shaft and the stop-element in the axial direction, whereby the stop-sleeve is mounted five-point and can be moved axially.
