I personally have 2 Mathey Dearman Pipe Bevelers. 2 to 4 and a 4 to 8 inch. I also have a Koike chain style beveler. The Koike cuts just as good as the Mathey but requires a little more set up time, however it will cut from 4 to 24 inch just by adding or taking out links. Got a real good deal on it. Only 25 dollars, it had been used only for one job when I bought it. The new owners of the company didnt know what they had.
