A table saw (also known as a sawbench or bench saw in England) is a woodworking tool, consisting of a circular saw blade, mounted on an arbor, that is driven by an electric motor (either directly, by belt, or by gears). The blade protrudes through the top of a table, which provides support for the material, usually wood, being cut. In most modern table saws, the depth of the cut is varied by moving the blade up and down: the higher the blade protrudes above the table, the deeper the cut that is made in the material. In some early table saws, the blade and arbor were fixed, and the table was moved up and down to expose more or less of the blade. The angle of cut is controlled by adjusting the angle of blade. Some earlier saws angled the table to control the cut angle. Types The general types of table saws are compact, benchtop, jobsite, contractor, hybrid, cabinet, and sliding table saws. Benchtop Benchtop table saws are lightweight and are designed to be placed on a table or other support for operation. This type of saw is most often used by homeowners and DIYers. They almost always have a direct-drive (blade driven directly by the motor) universal motor. Some early models used small induction motors, which weren't very powerful, made the saw heavy, and caused a lot of vibration. Most modern saws can be lifted and carried by one person. These saws often have parts made of steel, aluminum and plastic and are designed to be compact and light. Benchtop table saws are the least expensive (typically costing in the $100-$200 range) and least capable of the table saws; however, they can offer adequate ripping capacity and precision for most tasks. The universal motor is not as durable or as quiet as an induction motor, but it offers more power relative to its size and weight. The top of a benchtop table saw is narrower than those of the contractors and cabinet saws, so the width of stock that can be ripped is reduced. Another restriction results from the top being smaller from the front of the tabletop to the rear. This results in a shorter rip fence, which makes it harder to make a clean, straight cut when ripping. Also, there is less distance from the front edge of the tabletop to the blade, which makes
