Upper kitchen cabinets arrive tomorrow before next week's install. I need to drill 2 1/4" holes in the tops of these eurostyle cabinet boxes to accept LED puck lights. I've got the right size forstner bit, but... Is there a way to safely drill these holes by hand, or to maneuver them to be drilled on my drill press. The boxes are 42". I do want to drill from inside out to get clean holes on the visible side. I'm looking for any experience or ways to jig this to make this a comfortable task. Thanks in advance.
