Although there is a jig you can buy for this bit I decided to save some money and make my own. This bit saved time and energy and the holes were consistent. Every now and then it got jammed with wood chips but was very easy to unjamb by just pulling the sleeve back by hand. This will come in very handy when I get around to building shelves for my own home.
