Upon receipt I used this bit set to assemble the raised plate. The cuts were unusually smooth. The bit heights match. I've made comb notches, changed bits, and made notches on the bars without changing the bit height. The grate and grill are perfectly matched. Again, without changing the bit height, I cut out the raised panels. They fit perfectly. I had to use 3 rubber grommets (as Mark Sommerfeld recommends) in my porter cable router to get the bit into the collet properly. I recommend this bit set to anyone interested in making small raised panels.
