1. A hole cutter assembly operable to cut a plurality of different sized diameter holes in a work piece, the hole cutter assembly comprising: an arbor configured to connect to a power tool for rotation about an axis; a body coupled to the arbor for rotation with the arbor; a first arm moveably coupled to the body, the first arm extending generally perpendicular to the axis; a first cutting blade coupled to the first arm and moveable with the first arm relative to the body; a second arm moveably coupled to the body, the second arm extending generally perpendicular to the axis; and a second cutting blade coupled to the second arm and moveable with the second arm relative to the body; wherein the first arm and the second arm are oriented generally parallel to each other on opposing sides of the axis; wherein the body defines an aperture, and further comprising a drill bit removably received in the aperture for rotation with the arbor; and wherein each arm includes a plurality of notches formed along a length of the arm, wherein each notch selectively aligns with the aperture as the first and second arms move relative to the body, and wherein, when the drill bit is received within the aperture, a first portion of the drill bit is received in the notch of the first arm that is aligned with the aperture to inhibit movement of the first arm relative to the body, and a second portion of the drill bit is received in the notch of the second arm that is aligned with the aperture to inhibit movement of the second arm relative to the body.
