ABSTRACT:
A plug cutter has a main body portion having a longitudinal axis, shank portion extending axially from one end of the main body, and a plurality of blades extending axially from an opposite end of the main body. The blades are formed so that at least a portion of the inner surfaces thereof have a measure of radial relief with respect to the leading edges of the blades. A radial distance from the axis of rotation of the plug cutter to the leading edge of each blade is always less than the radial distance from the axis of rotation to any other portion of the inner surface. Accordingly, when a plug is being cut with the plug cutter, a gap is defined between an outer surface of the plug and the radially relieved portion of the inner surfaces.
