Yes, you can use the saw to cut laminate flooring.
Not very loud at all. If cutting metal, you may get a little screeching if the blade is worn, but normal use it's very quiet. I use a 5 gal shop vac with it and the vac is louder, by far.
Yes, you can, but you are limited by the distance between the blade and the guide. So it will work with smaller pieces but i would think a jig saw would be more practical.
You will have to use the PROPER blade in order to get a nice finished cut. You need a blade with a lot of teeth / inch, and you need to carefully run the material through your saw, keeping mind of the sound of the motor (saw). The sound of the saw will keep you aware of how hard the motor is working. e.g. Don't force the work through, causing binding, smoke, and maybe bending or even breaking the blade. (Consult the information that came with your blades regarding cutting across the grain, or with the grain). Finally, if you're cutting plywood, expect some tearing-out of the wood. A little more when crosscutting (across the grain). The addition of good duct tape on the bottom-side of the wood helps tear-out. And if your blade has been specifically designed to cut on the down-stroke, then you need the duct tape on the top of the wood. It's much easier to use this kind of blade because your cut-line is right on top of the work, on top of the tape...
Neither the table nor the blade tilt. They are fixed at 90 degrees to each other.
The cutting height, I recall, is about 2 inches. I have removed the guard and used the saw with the blade only. A longer blade could work but might not be safe. Certainly, use blades that are approved for the saw.
I believe it would, with the right blade. I've used it to cut 1 by stock, plywood, and even acrylic. I didn't have good results with acrylic, but that didn't pose a problem.
You would ruin it.
I had the same problem when I first got it (it was super loud, lots of chatter, cuts were really slow and inaccurate) but I switched the blades to some nice quality Bosch and it's night and day - It cuts fast and smoothly with almost no chatter. Replace the blades and you should be ok.
