A double cut is easier to control and takes smaller bites. I usually recommend either turning down the air pressure or better yet getting a router control at Harbor Freight for you electric grinder. Keep your burr clean buy dipping it in transmission fluid or wd40. Lots of ways to go about it but that will get you started. If you need burrs quickly Summit sells them.
