I used this bit to cut some 1x6 pieces to use as fairings in the workshop that I am building for myself. Although it was only jaws and this was my first time milling anything, I thought he did a great job. I have routed almost a hundred boards and so far the only problem has been not checking if the screw is still tight after routing a few boards which has caused the bearing and screw to come loose from the shaft. My sharp-eyed friend found the screw, so that wasn't a problem, but there's an extra screw in the kit if I need it. The racquet stayed sharp and caused me no problems other than my lack of experience. All in all money well spent. would recommend.
