I just put half-circles on the back edge of two desktops so I could pass power cords through them. I used a hole saw to cut a 2.5" diameter hole in a piece of 1/2" mdf. Then I clamped the mdf to the desktops and used a template bit to rout out the hole. Very nice, neat job. At some point I intend to make an mdf template with an assortment of circle sizes for future use.
