Most table saws - other than small bench top models - are equipped with induction type motors in the 1 - 5 HP range. On larger saws, you'll most often find a "totally enclosed, fan cooled" (TEFC) induction motor. A TEFC motor is designed for continuous duty and is sealed against dust and other contaminants - a significant advantage in a woodshop.
The quality of the table saw surface (or "bed") is extremely important to the overall performance of the machine. The table surface needs to be reliably flat and rigid to properly support the workpiece during a cut. As one of the most massive parts of the saw, the table surface also plays a major role in absorbing vibration. Because of the need for mass, rigidity and flatness, cast iron is the material of choice for the top of a table saw. On a quality saw, the table is made using a hefty quantity of cast iron and state-of-the-art foundry methods. The end result of the casting process is then precision ground to flatness in the .0005'' tolerance range.
A table saw is one of the most popular pieces of machinery used for woodworking. It consists of a circular saw powered by an electric motor that is mounted onto a table. In order to cut, material is pushed through the saw on the top of the table. It is used mostly for large wood projects such as fences, tables, book shelves, etc. When selecting a table saw it is important to know the different types and the pros and cons of each. The following are the four basic types of table saws and what they have to offer.
Most table saw trunnions are made to tilt either left or right (but not both) to a maximum of 45 degrees from vertical. If you have a choice, and you usually do, never buy a right-tilt saw for the following reason. A right-tilt saw tilts the blade towards the fence and can pinch a work piece into the fence, causing a jam or, worse, a kickback just as the cut is finishing. Further, on a right-tilt saw, the blade is tilting towards the fence and could cut into and ruin it if the fence were to be inadvertently moved too close to the spinning blade. A left-tilt saw tilts away from the fence and instead of pinching the work piece, allows it to rise vertically slightly, if need be.
There are four main classes of table saws: contractor saws, benchtop table saws, cabinet saws and hybrid saws. When deciding between portable and floor standing table saws, the main thing you're trying to do is balance durability with portability. Since most portable types of equipment do not have the same durability features, they typically do not last as long as their less portable counterparts.
