Essential Information on Table Saw Blades. On this website, I repeatedly maintain how useful table saws are and how much work you can get done if you learn to use them properly. At this point, we're going to assume you've done your homework and decided on a particular type of table saw, or maybe even a particular model, but your work is not quite done yet. Depending on your projects, sooner or later you are going to have to change the blade from the original one that comes with the table saw when you buy it. The choice of the right blade is crucial, and you will need to consider the type of material you will be cutting as well as its thickness.
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.
Table Extensions. extensionsIt's pretty easy to conclude that a larger table surface allows for the manipulation of bigger sheets of material and larger rip capacity. A lot of table saws have extensions located on the right of the saw which allow you to rip through large boards, or even 4 x 8 sheets.
I would also recommend you to look for switches that have a “sunk” or plastic cover which prevent you from turning the saw on accidentally. If you have kids running around the shop, consider a saw that comes with the ability to add a padlock. Actually, this comes in useful even if you don't have kids who are likely to gain access to your workshop.
Table Saw Safety Features. The most noticeable and probably the most important safety feature is the blade guard, because it's very effective at keeping your fingers away from the danger zone – the saw blade. Truth is though, that many woodworkers don't like the blade guard because they can't measure and see the cuts if it's attached, especially if the guard is not made out of Plexiglas. They also complain that things like changing the blade or removing stuck wood take more time, so they often decide NOT to use the blade guard.
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.
Blade Adjustments. Axis Adjustment Modern table saws allow the blade to be adjusted in various ways. The blade can be adjusted both vertically and by changing its axis. Vertical adjustments are made by exposing more of the blade, which changes the depth of cut. This comes in handy for thick pieces of wood as well as for non-through cuts. By adjusting the axis of the blade, you can make cuts at a certain angle, thus making bevel cuts, which are good for creating joints.
