Greenlee makes nice punches. I have a whole selection of them. But this one was mislabeled as a conduit punch, when in fact it was something different. My experience with conduit punches tells me they are not the actual size of the pipe but larger; usually about a 1/8th larger so, the electrical fitting will go in the punched hole. The 1 1/2 inch punch I got was exactly a 1 1/2 hole.
