The trunnion determines the accuracy of your cuts so you want to be sure that it is well built and accurately machined. The saw blade must always be exactly where you need it to be. Furthermore, the trunnion must be easy to operate. It should not require Superman to raise or tilt the blade. As time goes on, you may find that it is harder to turn the wheels or cranks that operate the trunnion. This is usually because of sawdust contamination of the gears and/or lack of lubrication. Some better saws have ways of eliminating sawdust from the cabinet into an external dust port before it can get into the gears. Other saws come with self-cleaning gear teeth.
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.
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.
Some of the nicer table saws have the caster wheels permanently mounted inside the cabinet so they are never seen and are never in the way. A foot pedal controls raising the saw up into the mobility position and then lowering it back down onto the floor. If your table saw does not have this feature, after-market mobility bases can be purchased as needed.
In the modern table saw, regardless of type, the depth of a cut is changed by adjusting the distance that the blade sticks out above the table surface. The more the blade protrudes from the table, the deeper the cut that is made in the material will be. Conversely, the less a blade protrudes from the table, the more shallow the cut that is made in the material being cut, will be.
