An attachment mechanism for a rotating surgical tool includes a mounting body defining a tool passage therein and configured for connection to a non-rotational component of the surgical tool, such that the tool passage is concentric about a rotational component of the surgical tool. The attachment mechanism further includes a ring arranged around the tool passage and rotatably connected to the mounting body. A mounting arm is attached to the ring such that rotation of the ring relative to the mounting body sets a desired circumferential position of the mounting arm relative to the tool passage, the mounting arm being configured to receive a tracking system emitter. An engagement mechanism is operable between the ring and the mounting body to maintain the desired circumferential position of the mounting arm.
