This cutter is an absolute waste of money .My analysis of this product showed that it was poorly made and could not withstand the pressure required to cut through even the thinnest tailpipes. It ended up bending out of shape before I could even make a decent cut. The only positive thing about it is that it was inexpensive, but you get what you pay for. This cutter is not worth the time or effort it takes to USE it. Avoid it if you value your time and automotive tools..
