This saw is the workhorse of my pool removal. Its lighter and gets the shallow cuts done for the larger saw. Get the right blades for your job, and the right quantity. I had hard reinforced concrete that requires special blades. There are good turbo blades that were fast, and there are other less "fast" blades that are for slower cuts in heavier rebar. The problem with fast blades is it easy to go off line, and that's a real problem. The lines have to be straight for the larger saw.
Make sure there is water on the cutting at all times, or you and the saw will breathe in concrete dust, not good. Protect your skin also, the slurry that spins off is a serious irritant.
