There are two types of motors used in table saws: universal motors and induction motors. With a universal motor, the power source is linked directly to the blade, providing a whole lot of power. The downside is that these models are generally quite loud. Induction motors, on the other hand, are connected to a belt that then transfers power to the blade. As a result, you get quieter operation and the ability to cut dense materials. The downside is that these models require more preventive maintenance, as you have to adjust the belt’s tension periodically.

For any kind of professional woodworking and large scale construction work, the cabinet table saw is the one for the job. These types of table saws are often called stationary saws.

You’ll need to find an accurate measuring tool to make sure your table saw blade is resting at a perfect 90 degree angle if you want to see the best results.

The best part is, these issues are a trade-off, considering the overall performance. You can purchase it without hesitating.
