I'm not a great carpenter but I have a mediocre DeWalt router that I use occasionally. I recently built myself a nice 30" x 72" x 1-7/8" maple log workbench. I've never been able to drill a straight hole, so I put a Whiteside bit in the router with plunge base installed and used it as a pilot hole drill bit so I could set up a vise. I was able to drill through most of the butcher block with a router and then 7/16" and 11/16" bits in a portable drill press. Do 5 /8" bolt holes. The 1/4" pilot holes were perfectly perpendicular, which is what I needed.
