Incredible precision, makes trimming a pleasure. Now I really believe in Freud, after looking at some cheaper options on Amazon I gave this one a try and will never go back. I used this drill bit to make a straight edge on a 1.5" thick board and I have to say it was the sharpest edge I have ever seen. It handled easily even when I tested it with a nice 1/4 inch lip over the bottom rail. It was so smooth I almost didn't have to attach the bottom guide plate, which often required multiple clamps when using inferior bits.
