Create a recess
Drilling holes with a drill press using a guide or jig makes sense when you have a lot of holes to drill. The problem is that sawdust and wood-shavings can build up and push your workpieces out of alignment. Drill perfectly placed holes every time, by creating a guide with a recess. The recess will prevent buildup and leave you free to drill a bunch of holes with out having to broom or blow the jig clean.
