Abstract
This invention discloses an improved cutting tool such as a counterbore cutter or piloted reamer that is comprised of a free-spinning pilot connected to the cutting tool. The free-spinning pilot allows the cutting tool to rotate within it while it makes firm contact with a pre-drilled hole in material to be cut improving the location of the cutter relative to the hole.
