The invention relates to a stop for arrangement on a drilling, milling or countersinking tool for machining a work piece, wherein the work piece has a surface, and wherein the drilling, milling or countersinking tool has a cutting section. The stop comprises a contact surface, wherein the contact surface is arranged such that once a predetermined machining depth in the work piece is reached, the contact surface is seated against the surface, at least in some sections. A connecting element is provided, wherein the connecting element is arranged between the contact surface and the cutting section. The connecting element is suited to prevent a relative movement between the contact surface and the surface.
