Title: Don't waste your money
Review: I purchased a set of 3 which included the 3/8" advertised here. After setting my drill press to the recommended 1000 rpm, I attempted to cut plugs in a variety of soft & hard woods. All of them came out with burn rings. I changed speeds on my drill press and also varied the amount of pressure. All attempts came to the same result. I ended up purchasing a 4 pronged set from Rockler and am very happy with the results. General Tools messed up on this one.
