Hole cutter with chip egress aperture

A hole cutter for cutting a work piece, comprising:

• a substantially cylindrical blade body defining a cutting edge and a longitudinal axis;
• a first aperture portion formed through the blade body and spaced from the cutting edge such that a portion of the blade body extends between the cutting edge and the first aperture portion, the first aperture portion configured to receive therethrough a lever for removing a work piece slug from an interior of the blade body and defining a first fulcrum configured for engaging the lever and for levering the slug out of the interior of the blade body;
• and
• a second aperture portion formed through the blade body and spaced from the cutting edge such that a portion of the blade body extends between the cutting edge and the second aperture portion, the second aperture portion configured to receive therethrough a lever for removing a work piece slug from an interior of the blade body and defining a second fulcrum configured for engaging the lever and for levering the slug out of the interior of the blade body by applying a sufficient levering force against the second fulcrum to lever the slug towards the cutting edge,
• wherein the first fulcrum is axially spaced from the cutting edge a first distance, the second fulcrum is axially spaced from the cutting edge a second distance that is greater than the first distance, and
• wherein the first aperture portion and the second aperture portion together define an aperture area, and wherein one of:
• (i) the blade body defines a diameter within the range of about ⅞ inch to about 1 7/16 inches, and a ratio of the aperture area to the blade body circumference is between about 0.18 and about 0.31;
• (ii) the blade body defines a diameter within the range of about 1½ inches to about 3⅜ inches, and a ratio of the aperture area to the blade body circumference is between about 0.10 and about 0.24;
• and (iii) the blade body defines a diameter of about 3½ inches or greater, and a ratio of the aperture area to the blade body circumference is between about 0.11 and about 0.21.
