I see that this thread is over a year old, but I still have the same question. I am cutting MTH ScaleTrax which mics out at .190 or code 190 rail. I'm using the Xuron 2157B cutters. The ScaleTrax does tax these cutters, but they do work with a little extra effort.
Jim, you stated "I use these, from techi-tool, even on code 148 rail, only cut top to bottom not side to side. They give a nice, flush cut on non-ferrous metals (do not use on steel rail)."
How do you think the Crescent cutters will work on code 190 rail?
