How to drill a hole

[Blind Bruce]

I need to get my feeder wire through cork roadbed, 2" of foam, plus 1/2" of plywood. I would like the hole to be as small as possible, 1/16 or so. Problem is that all of my small drills are too short. If it weren't for the plywood, I could use a still wire. What do you people do in this case?

You can get extra long drill bits from a machine tool supply company.I've got some that are a foot long. I don't think you'll find them smaller than about 1/16" though.

Yeah, Bruce, unless you want to do some difficult triangulation, or some instersecting lines drawn at precise angles, you are hooped. Out to Canadian Tire ya go.

I've got some from Vermont American that are 6" - http://www.vermontamerican.com/ that I picked up at a local (not a chain) hardware store. They only go down to 1/8" though.

Bruce,

Loathar's suggestion is the one that I was going to give you. You can try these links:

Production Tool Supply

McMaster-Carr

This one comes as small as 5/64" OD (slightly larger than 1/16") and up to 3-3/4" long.

Both are huge places but have a large variety of things.

Bruce, I also did a Google search on "long drill bits+1/16" and found this web site:

Looks like these are 6" long and come in a pack of three for ~$9. That may be the way to go. It's always a good idea to have a couple of back up bits - just in case one breaks. (NEVER happens to me...[swg])

Hope that helps...

Those foot-long drill bits are great, too! The mechanics who build the airplanes where I work use them all the time. If you're careful about the rotational speed you use, you can bend them some to reach a little around a corner where you couldn't hold the drill straight.

Thanks guys, I now have some ideas to follow upon.
