Abstract
The invention relates to a stop for a rotating drilling, milling or countersinking tool which comprises a stop sleeve which is freely rotatably coupled, by means of a sliding or rolling bearing, around the tool. A first bearing bush of the bearing supports the stop sleeve. A second bearing bush of the bearing sits in a rotationally fixed manner on a shaft sleeve. The shaft sleeve can be pushed and fastened on a shaft of the tool. In a secondary aspect, the invention relates to a drilling, milling or countersinking tool having such a stop.
