These bits work well in a special slotter or drill WITH A PUNCH ADAPTER, I have the last one, my old bits/chisels were in bad shape and had to be replaced. I can't believe all the negative reviews from people because it doesn't work in a regular workout. The video clearly shows how it is used in a slot machine. If you're not smart enough to realize they won't work with a regular drill press, you're too dumb to work wood.
