For blasting it will not be adequate, it'll most likely continually run and you will have to let it build up pressure before being able to use it for blasting. Have you thought about an 18v impact wrench? The Makita I have is my favorite tool-no noise from the air compressor and I can use the tool anywhere in the shop, house or yard. It is abou 200 with battery, but I had a couple batteries and got the bare tool off Amazon for 107 shipped...Larry
