Delta Drill Presses
If you are going to drill a single hole to join two boards together with either a countersink, counterbore, or counterbore countersink recess, it would require you to drill as many as four different size holes. The first hole would be a pilot hole, then a shank hole, and then drilling the countersink or counterbore. The fourth hole would be for a countersink counterbore hole. That’s a lot of work to drill one hole. Drill presses will give you the ability to do just that. Drill four holes in one.
