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.
In the past, table saw blades were meant to cut only wood, but they are now able to cut through metal, plastic, and other materials. Mind you, most blades are still fabricated out of metal, but some also feature special alloys and materials in the teeth, and various carbon composites for the body. Before deciding on a blade, you need to look at several characteristics such as its diameter, the material it's made of, the material it's designed to cut, number of teeth, maximum speed, and price, among others. Of course, the blade needs to match your table saw as well. Now, let's see how you do all that.
Safety Considerations. When making cross-cuts avoid using the miter gouge and fence at the same time. Why? Because when you slide the board towards the saw using a miter gouge the board will most likely bind against the fence. At this point I should remind you this will most likely cause kickback which will throw the board back at you, and at high speed! This is something you definitely don't want to happen – ever. My advice would be to dismount the fence, or set it a decent distance away from the board.
