Essential Information on Table Saw Blades. On this website, I repeatedly maintain how useful table saws are and how much work you can get done if you learn to use them properly. At this point, we're going to assume you've done your homework and decided on a particular type of table saw, or maybe even a particular model, but your work is not quite done yet. Depending on your projects, sooner or later you are going to have to change the blade from the original one that comes with the table saw when you buy it. The choice of the right blade is crucial, and you will need to consider the type of material you will be cutting as well as its thickness.
Riving knife an even better option would be to consider a table saw with a riving knife instead of a splitter. While both do roughly the same thing, there are some key differences between the two. The disadvantage of having a splitter instead of a riving knife is that the splitter is fixed, which means it doesn't move along with the blade. Because it's fixed, a splitter needs to be removed when making cross, non-through, and dado cuts. Unfortunately, many people tend to forget to put the splitter back in place when they start making rip cuts. So if you have a table saw which uses a splitter to prevent kickback, always remember to double-check that the splitter is in place.
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.
