Hole saw

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 one-piece sidewall having a first end and a second end opposite the first end, the cylindrical body also including a gullet formed in the one-piece sidewall between a leading surface, a trailing surface, and a bottom surface of the one-piece sidewall, the gullet extending through the first end of the one-piece sidewall, the cylindrical body further including a support aperture formed in the one-piece sidewall, the support aperture spaced apart from the first end and the second end, the support aperture providing a support surface that is offset from the bottom surface to help leverage and remove a workpiece plug from the cylindrical body;
• and
• a cutting tooth coupled to the first end of the one-piece sidewall adjacent the gullet,
• 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,
• wherein the support aperture includes a first surface and a second surface, the first surface parallel to the second end of the one-piece sidewall and positioned closer than the bottom surface of the one-piece sidewall to the second end, the second surface parallel to the second end of the one-piece sidewall and positioned closer than the bottom surface of the one-piece sidewall to the second end.
