The Allsaw AS175 is a great restoration saw that cuts through mortar and brick like butter. The only drawback of the saw is that it does not like new mortar and brick, it cuts, but quickly wears out on the blades. The dust coming from the saw is extremely small, almost non-existent. I like this part a lot. Overall this is a great saw, they just need to drop the price a bit. The selling point is a bit overpriced.
