Blade Teeth. Blade teeth the more teeth on a blade, the smoother the cut. The majority of blades have between 24 and 80 teeth, expect for blades specifically designed to cut through certain materials. Why would you go with more or fewer teeth? More teeth ensures that the cut is smoother, but it also means the cutting will be done more slowly. Fewer teeth means faster cutting, but the cut will be rougher. A word to the wise: Do NOT EVER attempt to make the cutting faster by pushing the wood onto the blade. The only thing this will do is cause kickback, which will eject the wood back at you at a high rate of speed and potentially hurt you severely. So just be patient.
On/Off Switch. The on/off switchThese days, table saws come with an on/off switch that allows for easy access should the situation call for it. Usually these switches are located at the front of the saw, and preferably the off button should be large enough to be operated using your entire hand (protected of course), elbow, or even your knee. The easier it is to switch the table saw off, the better.
Blade Sizing. Blade Sizes there are two ways table saw blades are sized: their outside diameter, and the diameter of the mounting hole. Most standard blades for table saws are 8, 10 or 12 inches in diameter, but there are blades as small as 3 3/8 inches in diameter and as large as 30 inches in diameter. The bigger ones are designed for specific commercial purposes, of course, but man, that's a big blade!
Splitter and Anti Kickback PawlsOne of the leading causes of table saw related accidents is kickback, which occurs when a piece of wood gets ejected at high speed, back toward the operator. This can cause some serious injuries. This happens when the wood binds between the fence and the blade, and then gets caught by the teeth on the back on the blade. In order to prevent that from happening, many table saws are fitted with a splitter. A splitter is basically a small vertical blade made of metal or plastic, which holds the Cerf open behind the table saw blade. It's a simple solution that works, up to a certain point.
Elevation and Tilt Wheels. Elevations and tilt hand wheel The blade elevation hand wheel is usually located on the front of the saw and allows you to control the height of the blade, which effectively controls the depth of cut. In the case of 10-inch blades, the blade should be exposed around 3-5/8 inches at its maximum height which is sufficient to cut through a 4 x 4 in a single pass.
Miter Gouge. An Angled Cut Using a Miter Gouge. How does a miter gouge work? It's pretty simple. In essence it is a guiding device that moves inside the miter slot on the saw. The key component is the piece that sort of resembles a half-moon, and pivots around the point of its connection to the guide. Thanks to the locking mechanism you can choose any angle between 45 and -45 degrees.
Choosing the wrong blade will result in poor woodwork at best, and turn into a potential accident at worst. Now, in order to get the most out of the saw you paid for with your hard-earned cash, and to avoid any saw-related accidents, you need to learn a thing or two about the blades. This short guide I put together should teach you what you need to know. Check it out.
