This is a smaller surface grinder that would be perfect for home machine shop. It needs a magnetic chuck which can be bought from ebay or you can use a vise! Needs a good deal of elbow grease but was working great last time it was used! It is 3 phase but you can get a small cheap phase converter which we run our 3 phase static phase converters! They actually pay for themselves within the first couple of months because it uses less electricity!
