Abstract:
A hole cutter has a substantially cylindrical blade body defining a blade body circumference, a cutting edge formed on one end of the blade body, and an axially-elongated slot formed through the substantially cylindrical blade body. The axially-elongated slot is configured to receive chips flowing from the cutting edge within the interior of the blade body and (i) into the slot and/or (ii) through the slot, to prevent the collection of such chips within the interior of the blade body and/or at an interface between the blade body and the work piece. The axially-elongated slot defines a first end adjacent to the cutting edge, a second end axially spaced further from the cutting edge, and a slot area. The hole cutter further defines a total slot area to blade body circumference ratio within the range of about 0.1 to about 0.3 depending on the size of the hole cutter.

Claim (Index 31):
A hole cutter for cutting a work piece, comprising:\n 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 \u215e inch to about 1 7/16 inches, and the aperture area is between about 10% and about 15% of the blade body area; (ii) the blade body defines a diameter within the range of about 1\u00bd inches to about 3\u215c inches, and the aperture area is between about 6% and about 13% of the blade body area; and (iii) the blade body defines a diameter of about 3\u00bd inches or greater, and the aperture area is between about 6% and about 11% of the blade body area.
