Claim 11:
12. The tool as claimed in claim 3, wherein said collar (13) has an elastic stiffness such that the tool (10) transitions from the rest position to the reference position when a force is applied to the holder (12) coaxially to the tool while the tool (10) is coaxial with the reference surface (40, 47) causing the holder (12) to travel a distance from the rest position to the reference position, where the holder (12) travels the distance at a set movement speed of 25 mm/s, and a ratio of a value of the force and a value of the distance traveled by the holder (12) from the rest position to the reference position is between 3 N/mm and 15 N/mm.
