A hole saw is a cutting tool used to make round holes in various materials. Also known as a hole cutter, the tool consists of a cup-shaped metal cylinder with a toothed cutting edge at the open end, usually with a drill bit to center the hole and prevent the saw teeth from slipping.

They are also less expensive than drills. Disadvantages include the need for a drill bit capable of generating considerable torque at low speeds, the tendency to jam if clogged with dust, and the possibility of core plugs getting stuck in the hole saw.

The saw consists of a metal cylinder mounted on a mandrel, usually made of steel. The cutting edge is formed with serrated teeth or industrial diamonds set into the teeth. The arbor, also called the mandrel, is responsible for attaching the bit to drill the hole and holding the pilot bit in place. Angled slots in the cylinder wall help to bring out the dust. The kerf of the cut (defined as the distance between the split saw teeth) is designed to be slightly larger than the diameter of the rest of the hole saw so that it does not get stuck in the hole.
