I tried a 90 I have becasue of Joes suggestion. It did cut a lot cleaner. The 90 is the same make and age as the 60 I had used, which may or may not mean anything. So what is it, the angle of the cut that doesn't produce as much tearout? Main problem with this one is I'm matching the font from a business card and a 90 or greater isn't going to get into the fine parts of the letters. I was barely getting there with a 60.
