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.
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 table saw is the heart of your shop. You will use it more than any other machine and its accuracy and capacity will determine the quality and size of what you will be able to produce. This is akin to picking someone to marry: Ideally, it's for life and you will have to live with your decision for a long time to come. Therefore, rushing into purchasing the first table saw you see, without doing your homework, is like a quickie Las Vegas marriage, always a gamble.
The bench top saw, also known as the portable saw, does not come all the way to the floor but is meant to be placed on top of a table for support. This is the more lightweight version of the table saws. They usually can be carried by one person from job to job.
A hybrid table saw is a lot like the contractor saw with a few key differences. For one thing, it is much more compact than the contractor saw and does not require as much room in your tool shed. The hybrid table saw also offers some of the features of the cabinet saw. With its solid and heavy base, it has the lower vibration of a cabinet saw along with dust control. A contractor saw or a hybrid saw of good quality suits the needs of most woodworkers.
