A reamer includes a shank, a washer, a ring and a blade. The shank is a polygonal rod and includes an annular groove made in a periphery and a bore made in an end. The washer includes a slot. The ring includes a circular opening. The blade includes an insert inserted in the bore through the slot and the circular opening. The circular opening is made of a diameter larger than a width of the blade to allow the blade to rotate relative to the ring.

In one embodiment, a method for forming a pair of aligned holes is provided. The method comprises determining a diameter of a cleanup hole associated with a plurality of misaligned holes, in which the cleanup hole diameter may also correspond to a fastener diameter. Additionally, a tapered reamer is at least partially inserted into a gap defined by the plurality of misaligned holes. The tapered reamer has a longitudinal axis and may be configured such that the longitudinal axis aligns with a center of the cleanup hole when the tapered reamer is inserted into the gap defined by the plurality of misaligned holes. The plurality of misaligned holes may then be reamed with the tapered reamer to form the cleanup hole defined by the plurality of aligned holes having a same center and a same diameter.
