Blade Types. Rip vs. Crosscut blades the two basic types of table saw blades are rip and crosscut blades. Rip blades have a smaller number of teeth and larger gullets, which means there's more room to remove the shavings and dust. These blades are designed to cut along the grain of the material on the table, but although they cut faster, the resulting cuts are rougher.
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.
The blade tilt hand wheel is located on the side of the saw and allows you to tilt the blade up to 45 degrees away from the fence. The hand wheel which allows you to adjust the tilt of the saw blade is usually located on the left or right side of the unit depending on which way the arbor is made to tilt. Portable table saws usually don't give you as much control as professional cabinet saws though, and they often combine elevation and tilt adjustment in one wheel.
Obviously, the easiest way to know which blade fits your table saw would be to consult the instruction manual. Also, use some common sense. There is a finite amount of space inside the arbor, so you can't use just any blade. The space is also limited with the presence of a blade guard. Speaking of the arbor, the central arbor hole on most table saw blades is 5/8 inches in diameter, but then again, there are exceptions to that rule. If the diameter and the arbor are supported by the saw, you are on the right track.
There are some differences between T-square fences found on table saws. Some of them make use of bolts in order to mount the fence tube to the T-square head which is more like a characteristic of lighter duty fences found on hybrid and contractor saws. Heavy-duty fences found on cabinet saws have the fence tube welded to the T-square head.
When you are making angled cuts simply align the sheet with the straight part of the miter gouge, and push it together with the miter gouge toward the blade. The saw will make the cut at an angle using the pivoting part of the miter gouge. Whereas fences allow you to make rip cuts, miter gouges provide you with a lot more options. You can make both square and angled cross-cuts as well as specialty cuts. In order to make a cross-cut, you need to slide the miter gouge back toward you. You then need to put the board against the straight part of the gouge.
The Fence. One crucial component of every table saw along with the engine and blade is the fence. In fact, making a precise rip cut would be impossible without it. There is basically one type of fence most table saw manufacturers tend to use, but before we get into that let's go over the main characteristics a good fence should have. First of all the fence should allow for easy and hassle-free adjustment both horizontally and vertically. The fence should also sit on the rails firmly, and there should be NO “wiggle” room apart from the sliding.
