Patent ID: 7416082

Claim:
A hanger and a drill that has a drill point and also that has drill helices, said hanger comprising: a tag face having an upper area with a hole for receiving a hanger; and at least one holding part that is located on said tag face and that expands radially outwardly and is elastically deformable in response to said drill when it is inserted therein with the point of said drill penetrating said elastically deformable holding part, said elastically deformable holding part being an upper holding part that forms a ring surface that defines a cone in the center of the ring surface for receiving and holding said drill, wherein the lower area of the cone is larger than the diameter of said drill, said drill hanging from the holding part to force-close said cone such that the wall of said cone settles against the outer circumference of the drill to hold said drill by the elasticity and by the shape of said cone, said cone at least partially enveloping the drill and enclosing the outer circumference of said drill in a frictional fit to hold said drill by the drill point.
