'

Hole saw, also known as a hole cutter, is a type of drill bit that consists of a circular saw blade body and is mainly used for making holes larger than those made by a twist drill bit. It is primarily used in woodworking, but it can also be used in some plastic, laminates and even metal.

Hole saws range in size from tiny ones used for making jewelry and watch parts to large ones used for tasks such as cutting out the holes for door knobs in a door. They can be used for a variety of tasks such as cutting holes in walls, sheetrock, and other materials, as well as cutting the core out of tubs and showers, and creating the necessary openings for electrical boxes, junction boxes, and air ducts.

To use a hole saw, you must first secure the material you are going to cut in a vice or other secure device, then attach the hole saw to a drill (either cordless or corded). Place the hole saw on the material and make sure it is centered on the mark, then press the drill trigger and plunge the saw into the material. Once the saw blade has plunged, allow the saw and drill to do their job. As the saw is cutting, the sawdust created should be extracted away from the workpiece using an exhaust system attached to the drill. When the saw blade has completed its cut, carefully remove the saw from the material.

Hole saws are a great tool for making precise, clean cuts in wood, plastic, laminates, and even metal. With the proper care and maintenance, a hole saw should provide years of reliable use.
