Systems, methods, and devices are disclosed for navigational arrays for attaching to surgical tools, the arrays comprising a frame comprising fiducials for detection by an optical navigation system, and a body having a first end for supporting the frame and a second end defining an opening, wherein the opening is aligned with a first axis of the surgical tool, wherein the opening engages a stationary surface adjacent to the surgical tool, and wherein the opening engages features disposed at predetermined even intervals on the stationary surface adapted to allow repositioning of the array from a first position to a second position, wherein the second position is at least one of a rotational offset or an axial offset from the first position. The stationary surface may be a step disposed on an adapter inserted into the surgical tool. The stationary surface may be a sheath covering a rotatable shaft inserted into the surgical tool. The stationary surface may be a sleeve disposed on the surgical tool. The arrays may be part of a computer-assisted surgical system.
