The advantages of hole saw

The advantage of hole saws is that they can cut holes without cutting the core material. For relatively large holes (greater than 1 inch), this is preferable to twist or shovel drills. They are also cheaper than drills. Disadvantages include the need for a drill bit capable of producing considerable torque at low speeds, the tendency to clog if clogged with dust, and the possibility of jamming the core plug on the hole saw.

The hole saw consists of a metal cylinder mounted on an arbor, which is usually made of steel. The blade is formed with serrated teeth or industrial diamonds set into the teeth. The cutter bar also called the arbor, is responsible for attaching the drill to drill the hole and keeping the guide bit in place. Angled slots in the cylinder walls help to carry the dust-out. The cut kerf (defined as the distance between the teeth of a split saw) 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.
