This seems to happen more than often in the agraffes I have repaired. The surface of the stub is rarely flat across. I have had good success, when needing to drill and remove, (as opposed to those glorious days when the broken piece moves under a sharp probe and you know you can tease it out!), by making sure that the first, light, punch mark I make on the broken stub is in the middle of the piece, and then the second or third heavier tap is slightly angled towards the high side of the surface. This usually lets the drill go in straight from the beginning. I also carefully use a much smaller drill bit than the ez-out will call for , then go up to the appropriate size once I know that the hole is straight down the middle.
