If finer cuts are what you have set out to achieve, a crosscut blade is the better option. The resulting cut is much smoother, but because the teeth have less space for chip removal and because there are more teeth to cut through the wood, the feed rate is much slower. If you need both speed and smooth finish, there are combination blades, which attempt to do both. Also, you may come across special cut blades. These are either designed to cut through certain materials like plywood, hardwood, metal, plastic, or even brick, or they are designed to make specialized cuts for the purpose of joint making. This includes sets of dado blades.
Instead of having you scavenge the Internet for what seems like forever in order to get the information you're after, I decided to compile this guide which explains most table saw basics. I am not going into things like rip fence and saw blades because they require more attention (and are therefore discussed in separate articles elsewhere on this website), here we'll discuss the more basic stuff. So, without further ado, let's take a look at what you can expect to be included in the price on most models of table saw out there.
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.
