I bought it thought that I wanted to use it for cutting aluminum plate, but abandoned because the grinding stone was thick and the cut face was dirty, I could not cut it straight. Eventually it was a plasma cut. The fine one, the golden egg is cut.
Up to now it has been cut with multi-use cutting whetstone, so we are comparing it, but it is only written for aluminum, it is cut out and it is much less sticky. I will try to change the grinding stone according to the material without going on later.
