On/Off Switch. The on/off switchThese days, table saws come with an on/off switch that allows for easy access should the situation call for it. Usually these switches are located at the front of the saw, and preferably the off button should be large enough to be operated using your entire hand (protected of course), elbow, or even your knee. The easier it is to switch the table saw off, the better.
I would also recommend you to look for switches that have a “sunk” or plastic cover which prevent you from turning the saw on accidentally. If you have kids running around the shop, consider a saw that comes with the ability to add a padlock. Actually, this comes in useful even if you don't have kids who are likely to gain access to your workshop.
There are some differences between T-square fences found on table saws. Some of them make use of bolts in order to mount the fence tube to the T-square head which is more like a characteristic of lighter duty fences found on hybrid and contractor saws. Heavy-duty fences found on cabinet saws have the fence tube welded to the T-square head.
Blade RPM. The maximum speed of a blade is usually expressed in RPM (revolutions per minute). One thing you need to look for is the speed of the table saw, which must never exceed the speed of the blade. Blades are designed to rotate at a certain speed, and using it on a table saw which exceeds that speed will cause the blade to break apart due to centrifugal force. This is pretty much everything you need to know about blades. If you decide you want to learn even more about blades and their properties, this should serve as a good base for you to build upon.
Now, the most common type of fence found on table saws at the moment (especially the cabinet type) is the Biesenmeyer Commercial “T-square” fence, or in most cases manufacturer's copies and offshoots of that design. It's the most popular design because it is easy to adjust and operate, is made out of welded steel, accurate, and best of all there is not much that can go wrong with it.
Blade Materials. Diamond tipped masonry blades that are meant to cut plywood and hardwood are usually fabricated out of metal, but those that are designed to cut through harder materials require the use of even harder materials. The harder material is applied around the edge of the blade, with the metal core remaining intact.
Fence and Miter Gouge Considerations Explained. Table saws are used primarily for ripping lumber, and in order to rip wood down to the desired width every table saw needs a fence. It's one of the most crucial components, so I thought the information below would come in handy for a lot of you.
