Abstract

See full text

A hole cutter can include a cylindrical blade body with a cutting edge and one or more axially-elongated apertures. Each axially-elongated aperture can include a first fulcrum axially spaced from the cutting edge, and a second fulcrum axially spaced further away from the cutting edge than the first fulcrum. The blade body can also include a third fulcrum defined by a second aperture different from the one or more axially-elongated apertures. The third fulcrum may be spaced closer to the cutting than the first and second fulcrums. A lever, such as a screw driver, can be inserted into the apertures and placed against each of the fulcrums to lever slugs out of the interior of the blade body. The third fulcrum may alternatively be defined by another axially-elongated aperture that is located a different distance from the cutting edge than the axially-elongated aperture containing the first and second fulcrums.
