1. A hole saw movable about a rotational axis in a cutting direction to cut into a workpiece, the hole saw comprising: a cylindrical body including a sidewall having a first end and a second end opposite the first end, the cylindrical body also including a gullet formed in the sidewall between a leading surface, a trailing surface, and a bottom surface of the sidewall, the gullet extending through the first end of the sidewall and defining a central longitudinal axis, the cylindrical body further including a support aperture adjacent the gullet, the support aperture entirely surrounded by the sidewall, wherein the gullet defines an area, wherein the support aperture defines an area, and wherein the area of the gullet is greater than the area of the support aperture; and a cutting tooth coupled to the first end of the sidewall adjacent the gullet, wherein the support aperture defines a longitudinal axis that is perpendicular to the rotational axis, and wherein an entirety of the support aperture is positioned closer than the bottom surface of the sidewall to the second end, wherein the support aperture includes a first surface and a second surface, the first surface and the second surface parallel to the second end of the sidewall.
