A method for hole repair comprising:
- selecting a hole for repair, said hole for repair comprising a damaged hole having an elongated axis;
- defining a repair diameter on the elongated axis, said repair diameter being the minimum possible diameter that completely encompasses the damaged hole;
- selecting a bottom cutting step up reamer with a bottom cutter integrated on a shaft having a first end with attachment features adapted to be received in a chuck and a plurality of bottom cutting edges substantially perpendicular to the shaft with step up reamer lands proximate the plurality of bottom cutting edges and spaced toward the first end having a plurality of cutting edges substantially parallel to the shaft with a maximum step up land diameter equal to or slightly larger than the repair diameter;
- aligning a centerline of the shaft of the bottom cutting step up reamer with a new center point on the repair diameter;
- and,
- creating a new hole start with the bottom cutter.
