A rip blade is designed to cut with the grain of the stock. It has a limited number of very deep teeth, to help clear away the material that is cut. A rip blade will cut with the grain very quickly, but won't leave the cleanest of finishes.
A crosscut blade cuts with kerf using chisels or carbides that alternate between cutting wide left and wide right every other tooth. This can produce a very fine finish on most materials when crosscutting.
There are specialty blades for cutting other materials, such as diamond-tipped blades for cutting masonry, or hardened blades for cutting steel and aluminum.Specific to woodworking, another common type of specialty blade is the dado blade. The two types of dado blades are "wobble blades", where the blade is adjusted to a particular angle to create a dado, and stacked dado sets. Wobble dado blades can create a considerable amount of vibration, which can be a bit unnerving when in use. Additionally, wobble blades don't leave the cleanest dadoes for your joinery.
