December, if this seems to be coming from left base here.
To try and avoid the 15 minute long talk about cutting utensils like I did on the drill press video, I'll talk about your various options as far as blades not in the video.
You'll also notice that this blade has carbide tips, which are the rectangles tipping each tooth. The cost difference between a carbide blade and a simple steel blade is significant, but if you're doing fine woodworking, carbide is a difference worth its price. On the other hand, if you're using your tablesaw to hack up the old cherry tree from the backyard for firewood, for all that is mighty, please make sure you're not using a carbide blade.
radial arm saw than the table saw, but if you get 10 inch equipment for both, you can use it on either. The cross-cut saw can be recognized by the fine-spaced teeth angled in alternating directions, which do a very good job of severing the grains as the wood crosses the radius of the saw, but aren't as good at removing the bulk material you need for rip cutting. Again, the pictured blade is carbide-tipped, which is an easy way to spot a much nicer saw blade. These two carbide saw blades have lasted us decades, so it's hard for me to say that the investment wasn't worth it.
The careful reader will then ask about plywood. Plywood is the very common and cheap building material that, if you stop and really look at it, is actually several very thin layers of wood glued together, with their grains at right angles. This is great because it means plywood is more isotropic than traditional wood board (it's more consistent as far as strength in one direction or the other due to the grain), but when you're cutting plywood, do you use a cross-cut blade, or a rip blade? You'll always be cutting the wood half rip and half cross, so what is a man to do?
Wood veneer is the very thin layers of wood which are glued together to form plywood and the wood grain surface of particle-board desks and shelves. The veneer saw's teeth are almost exactly the same size as the plywood saw's, but you will notice that the side of the saw has an angled lap to it, which helps to prevent tear-out or chipping when you are trying to cut the extremely thin veneer (usually <1/8 inch). This lap, unfortunately, only goes in about an inch of the radius of the saw, so using this blade to try and cut thicker material (or even plywood) isn't advised., since the saw gets quite a big thicker above this lapped radius, and you really shouldn't be using such a specialized saw for anything else anyways.
dado set. Dado sets are a series of blades of different thicknesses which can be combined to form a single cutting face of variable width. This is used to cut dados and grooves in wood, which are the cuts part-way through material at joints to act as a recess to hold perpendicular boards. The classic application of a dado is the joints in a bookshelf (before Ikea came in and replaced every wood joint with pegs and dowel nuts) where the shelves insert into the side panels.
So that's it as far as my collection of saw blades. Again, please don't think that this video and post are enough to learn how to use a table saw, so make sure to read your owner's manual, and get professional training if available.
