Abstract:
A hole cutter has a cylindrical blade body including a cutting edge and one or more axially-elongated apertures formed within a side wall of the blade body. The axially-elongated aperture is configured to receive a lever, such as a screwdriver, therethrough. Each axially-elongated aperture includes a first fulcrum axially spaced adjacent to the cutting edge, a second fulcrum axially spaced further away from the cutting edge than the first fulcrum, and optionally a third fulcrum axially spaced between the first and second fulcrums. A lever, such as a screwdriver, can be inserted into the aperture and placed against each of the fulcrums to lever slugs out of the interior of the blade body.

Claim (Index 11):
A hole cutter 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; 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 at least a portion of the first aperture portion and at least a portion of the second aperture portion are aligned along a line substantially parallel to the longitudinal axis; and wherein at least one of the first aperture portion and the second aperture portion is bounded by a bottom edge axially spaced a third distance from the cutting edge, a top edge spaced a fourth distance from the cutting edge greater than the third distance, and a side edge connecting the bottom edge to the top edge and oriented at an acute angle to the longitudinal axis of the blade body.
