Ok I need some advice regarding diamond blades and concrete cutting. I will be using it for mostly cutting cured concrete,but it may see some sawcutting for contraction joints. Is there a brand or style that anyone recomends? Are the ebay cheapos worth anything for the price? I am really unsure on the type grit and hardness on the blades and what I really need. Also, do youall usually cut wet or dry? I dont like the slurry when cut wet(its almost impossible to remove, but I dont like the dust when cutting dry also. I am told that blade life is increased by 25% when cut wet. Is there any truth in that? I have not done any long distance cutting, but what kind of distance can I expect out of a 14" blade cutting 4" concrete on average? Any reviews, recomendations, or advice would be apprciated.
