The saw consists of a metal cylinder, usually steel, mounted on an arbor. The cutting edge either has saw teeth formed in it or industrial diamonds embedded in it. The arbor can carry a drill bit to bore a centering hole. After the first few millimeters of cut, the centering mechanism may no longer be needed, although it will help the bit to bore without wandering in a deep hole. The sloping slots in the cylinder wall help carry the dust out. The kerf of the cut is designed to be slightly larger than the diameter of the rest of the hole saw so that it does not get jammed in the hole.
Holes saws for use with portable drills are commonly available in diameters from 6 to **0 mm (0.*4 to 5.1 in). The only limit on length of the cylinder, and thus depth of the hole, is the need to remove the bit from the hole to clear dust. A **0 mm (*2 in) cylinder length is not uncommon, although shorter bits are usual. By breaking the core off from time to time and using a shank extension, a diamond core drill can drill to depths many times its length.
Saw teeth are used for most materials, such as wood, plastics soft plaster, and metal. Diamond hole saws are used to bore holes in brick, concrete, glass, and stone.
