Topic tags/keywords: holes rebore re-bore drilling

I am looking for suggestions on re-boring 5/8” holes to 3/4” holes with a 5 degree angle in a work top. I cannot use the drill press…I need to use a portable drill. Any suggestions or assistance would be GREATLY appreciated.

Hey Randy
there are a couple of ways you can re drill, you can plug the 5/8 hole with a dowel cut it off and redrill,
You can put a small piece of 1/4 ply or any wood over the hole with double sided tape drill a very small hole in the middle from the back or have an x on the small piece so it is centered. or borrow or buy a step drill bit that has several sizes on one drill bit. the 5 degree part can be done buy setting a t bevel or angle gauge to 5 degrees and holding your tbevel next to were your drilling and drill using you bevel as a line of site. It still would be more acurate if it could be done on a drill press by tilting the table 5 degrees.

are you installing bench dogs? you may could just go up in bit size 1/16 at a time, slowly, or maybe use a forstner bit. i use a portable drill guide


on either jig, you can apply a few pieces of tape to one side until it leans 5 degrees. forstner would be cleaner i suppose.

Yes I am…The portable drill guide is what I was thinking, but I wanted some expert opinions before proceeding. Thanks!

Do you have access to a drill press? Could you bore the correct diameter hole in a wood block at the correct angle and then use this as a guide for drilling your bench dog holes? Just a thought.
