I am a hobby carpenter with a very good carpentry shop. I am selective about the instruments I buy and expect them to live up to my high expectations. I don't know why it took me so long to invest in cutters and not cutters. I now use Bosch clip-on wing bits for many router table operations. They are best used for cutting grooves for inserting the drawer bottom into the sides of the drawer frame. Also perfect for adding slits along the top edge of small box projects if you glue the box with the lid in place and then saw the top and bottom as a final step. While I could fit a blade/box blade into my table saw, connecting the wing cutter to the shaft in the router table and setting the fence is much quicker. The best part is the clean cut they make and the groove doesn't get clogged with sawdust. I thought these big rotary bits would feel unsafe but the way the wood cuts easily and the lack of recoil gives me complete confidence that I am working safely. I have three sizes now and will complete the full set because I love them so much.
