When I made the big jump into buying some boro tubes and rods, I realized I had no idea how to cut them (I'd never cut the moretti, they just seemed an ok size already). My husband put one of our dremel bits that is a tungsten carbide bit into a table vise, and I just go over there and scratch them 3/4 of the way around. Then, according to the genius Homer Hoyt, I wet the spot on the tube or rod and touch it with a molten rod at the scratch. You hear a little crack, and it makes a great even crack all around. Works every time, nice even cuts!
