I am brand new to routing. I read all the directions, watched several videos, and practiced on scrap wood before beginning my project but still I broke the 1/8” straight bit almost immediately—I was not taking off too much material. My router was mounted in a table. I later realized that because that bit in particular is so thin, it probably needed extra care and perhaps it was not a good one for a novice to start with. I moved on to the 1/4” straight bit and then the Roman ogee with no problems. I do notice that after a relatively small project, they are not nearly as sharp as they were.
This is a very nice assortment for me as a beginner. I had everything I needed for my first project. I also like the convenient wood case that they come in—for keeping them organized and they are all nicely labeled with the little picture to show what kind of cutting each bit will do. For a novice, I found that to be very helpful in choosing which bit to use for my project.
I’ll have to find a replacement for the 1/8 inch bit that I broke, but otherwise, I am pretty pleased with these bits. My first project looks very professional.
