Blade Materials. Diamond tipped masonry blades that are meant to cut plywood and hardwood are usually fabricated out of metal, but those that are designed to cut through harder materials require the use of even harder materials. The harder material is applied around the edge of the blade, with the metal core remaining intact.
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.
Safety Considerations. When making cross-cuts avoid using the miter gouge and fence at the same time. Why? Because when you slide the board towards the saw using a miter gouge the board will most likely bind against the fence. At this point I should remind you this will most likely cause kickback which will throw the board back at you, and at high speed! This is something you definitely don't want to happen – ever. My advice would be to dismount the fence, or set it a decent distance away from the board.
Another option to think about is the magnetic switch. You can read more about this on my page about safety features, but in short this will prevent the motor from dangerous automatic restarts after power interruptions. A magnetic switch is more common on cabinet saws, but you may want to consider an upgrade on your contractor as well.
Dust Collection. Dust collection port Having sawdust all over your workshop and work surface is not only annoying, but it can make your job more difficult. It's much easier to work with wood if the table of the saw is smooth and clean. For this purpose most table saws have dust collection ports which can be attached to a vacuum. You may also come across saws that have a cloth pouch which you can attach to the saw so it collects all the dust in one “tidy” place.
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.
In Conclusion. As you can see there is not much to making rip, cross, or compound cuts. Using the fence and miter gouge is something you can get the hang of very quickly. But as easy as it is, the biggest mistake you can make is to become complacent when using a table saw. Remember you are handling a very powerful tool with an incredibly sharp blade that rotates at several thousand RPM. Always make sure to follow the safety measures, and you will be fine.
