We're rehabbing the house next door and the disgusting pink cast iron tub had to go. We didn't want to do any more damage than necessary so beating it into a thousand razor sharp shards was out of the question. It took me about 1-1/2 hours to completely cut this cast iron monstrosity into three pieces with my angle grinder. The blade works equally well on some cement blocks I needed to cut and even after all this it still works great. Wonderful tool at a great price.It was delivered.Great price for this item, fast shipping! Worked out greatSo far I have cut concrete, bricks and pavers for projects around my yard. This blade has been use wet or dry and I have love using it for the price definitely will be in the near future buying more of them.GoodI am in the process of removing the old grout from a 100 year old chimney and this saw blade is working great. With more than 60% of the grout removed so far, the blade is still working like new.Grinding blocksI can cut really small crosses from stone with this blade easily.
