Cheap junk. If I could give zero stars I would. When I first used it, this bad boy pulled almost all of my teeth out of the cup before I even got past the halfway point of the steel plate. I'm cutting through a 1/4 thick plate of steel. I used cutting oil and worked slowly, but it still broke. Save money and don't buy. It's advertised as being able to cut metal but it might be good for wood but that's it, maybe aluminum. I was so disappointed as it looked so strong and sturdy when it arrived.
