I want to drill long ways through a 4 x 12, then as far as I can into
another. I want to then insert a piece of rebar in the hole. I
estimate the hole will be 24" deep. Are there 5/8" bits this long?

I've got one of these:

and one of these:

http://www.greenlee.com/products/EXT...oduct_id=17381

Together they make a 36" long 3/4" bit. I've never drilled through that
much solid lumber with it, but I think it would work if you back it out
on occasion, and if you make really sure that the set screws on the
extension are tight. You wouldn't want to leave the auger in the hole
permanently.

Irwin (and other companies I'm sure) make augers and drill bits at lease
30 inches long.

The challenge is drilling straight through the 4x12 and staying on center.
An alternative I've used for similar jobs with smaller stock is to rip
the board, route a channel, then glue it back together. It shouldn't be
too tough to get the bit to come out the other end without breaking
through one of the sides, but if you need it to be precisely on center
it may be a problem.

I have a 27" x 5/8" auger for making holes in gate posts.
Probably more than 100 years old. Works perfectly and drills true.
It is mandraulically powered. You might find something in your neck of the
woods.

Yes. You can get auger point bits upto six feet long from any alarm
installation distributor.

We had a bit and drill similar to that when I worked for Arizona Telephone
Company for drilling poles. It had an arm strong engine.

Now imagine using it while supported by your climbing hooks and belt.

I have a bit I use on pilings and dock work.
It is about a 5/8 wood bit welded onto a long shaft....
Works wonderful.
I use a power driver, and pull it out continuously.......
It is a ship auger bit......and helps move the debris up and out...
The shaft is smaller than the actual bit so that debris has room.

They make extensions in other sizes too.

Long bits are commonly available, even at HD. But after you price them,
an extension and a current bit may look more attractive!


Together they make a 36" long 3/4" bit. I've never drilled through that
much solid lumber with it, but I think it would work if you back it out

Good advice.

The speedbores from Bosch claim to do a better job of clearing out
debris, that is a long way to go though.

Having done what you are going to do several times I am curious as to
the size of rebar you plan to use.

Nothing that long will clear chips without frequent withdrawal.

I ALWAYS grind a flat spot on a bit where the extension set screw grabs the
bit. To not do so invites disaster, IMHO.

I'm sure that's true.

The Greenlee folks thought of that. It's hard to see in the photos, but
the shaft of the bit and the recess in the extension are both a
triangular cross-section.
