The Dowl-It 1000 automatically centers 5 sizes of holes on the edge of any board 1/2″ to 2″ thick: 1/4″, 5/16″, 3/8″, 7/16″ and 1/2″. Just line up on your mark, turn the handle to clamp in place and drill your hole. Uses standard-length twist or brad point bits that you supply. Can also be used for drilling into round stock.
