A: Dear we5inelgr, Yes one 14" Dual Purpose walk behind Saw Diamond Blade will work for the material and cutting you need to make. Should you have any other questions please feel free to reach out to our Rigid Tech Support Line at 1-866539-1710 so we can assist you.
A: Yes. It's great for cutting and rebar 1/2 inch
A: if you are cutting a two inch overlay with water you should get more . provided you aren't pushing the saw. if you are cutting standard 2 in thick pavement , you are cutting too deep, base and dirt love to eat blades
A: Not sure exactly but I just got mine and cut about 50FT. of 2"-3" asphalt dry and it certainly kept moving thru with no issues. The fact that you will do it wet will probably be even better for you. For the money you can't go wrong and if you don't like it for some reason, I think Home Depot would be more than willing to exchange the blade or give your money back. Good luck.
