Hole saw
A hole saw includes a cylindrical body having a sidewall with a first end and a second end opposite the first end. The cylindrical body includes a gullet formed in the sidewall between a leading surface, a trailing surface, and a bottom surface of the sidewall. The gullet defines a central longitudinal axis extending between the first and second ends of the sidewall that is obliquely oriented relative to a rotational axis of the hole saw such that the gullet is angled from the first end to the bottom surface in a direction toward a cutting direction of the hole saw. The gullet has a dimension measured parallel to the rotational axis between the first end of the sidewall and the bottom surface of the gullet that is greater than 1.5 inches. The hole saw includes a cutting tooth coupled to the first end of the sidewall adjacent the gullet.
