A hole saw is a cylindrical-shaped saw blade which can be used to cut perfectly round holes of varying sizes in a diverse range of construction materials. Hole saw cutters are used in combination with a power dill. As hole saws only cut around the perimeter of a hole, they are usually faster and more efficient than standard drill bits and are the preferred choice for cutting larger holes. More precise than twist or spade drill bits, hole saws can offer a neater finish and eliminate the need for more complex cutting work. Typical applications of hole cutters include creating holes for pipework, plumbing, and wiring.
