A hole saw or holesaw is a circular shaped hole cutter, that can easily cut a perfectly round hole into a material, without having to cut up the centre of the material. Generally, hole saws use a pilot drill bit, often called an arbor, at the centre of the saw to prevent the teeth from walking and offering a smoother, more accurate cut. The main benefit of using a hole saw is the fact that less effort and power is required for the power drill to power cutting the hole, which in turn saves energy and preserves the battery life of cordless power tools. Hole saws are used by plumbers, electricians and builders for a variety of applications like:

• Installation of door hardware


• Creating holes for pipework, plumbing or electrical cabling and wiring


• Installation of drainage pipes


• Installation of light fixtures


• Creating holes or vents in masonry
