Abstract:
Tools and methods for creating a plurality of aligned holes from a plurality of near full-sized holes. The tool includes a cutting member having a first diameter and a pilot member connected to and coaxial with the cutting member. A first section of the pilot member includes a centering member and is positioned between the cutting member and the second section having a second diameter. The centering member may include a cutting surface. The second diameter corresponds to a positional tolerance of misalignment of a plurality of near full-sized holes of the same diameter and a full-size hole diameter. The centering member may have a third diameter between the first and second diameters. The centering member may be tapered. The pilot member may be inserted into a plurality of near-full sized holes and the cutting member may cut through the holes to form a plurality of aligned full sized holes.
