This is my first post and am pretty new to woodworking. I am working on a project that requires a 3/8" hole bored into a 1 1/4" round red oak post. I keep tearing the wood on the backside when the drill exits. I'm using a brad point drill, I have tried different speeds and feed rates. I'm using a wooden V block to hold the piece. Any suggestions would be helpful.

Thanks,

JimA

Try a Forstner bit, and go really slow on the last part (feed rate). Or drill a very small pilot hole (1/16"?) then drill 1/2 way through from each side using the pilot to center your brad point.

Oh, and welcome Jim.

Thanks Daren, I'll give it a try.

Daren has the right idea but I find that I still get some tearout unless the wood is completely supported with scrap wood on the backside. If I can't do that I will drill until just the very point of the brad point or forestner bit comes through. Then I will turn it over and drill from the other side. The small center hole helps light it up.
I've only tried it once with moderate success but wrapping masking tape around it and then drilling really slow with a very sharp forestner bit did stop the tearout on one project. I don't know how much the tape helped because I didn't try it without the tape.

Try drilling an 1 1/4" hole through a piece of scrap wood. Cut it in half and then use it as a sacraficial piece by clamping the round red oak piece into the half pipe of the scrap piece. Then when you drill through your red oak it is fully supported at the exit point

Bingo! We have a winner :thumbsup:. (make the cradle from hardwood scrap, and don't reuse it, it is only good for one exit hole)

Thanks to all of you for the excellent suggestions. It's good to find a forum that is quick to offer help. (I thought you guys would think it to be a pretty juvenile question)

Thanks,

Jim, there are NO juvenile questions except those which aren't asked. You can not learn unless you ask questions, so consider the on-line woodworking community as you own personal woodworking "Wikipedia" source. After all, that's part of the reason for these forums.:thumbsup:

As Nancy says. There aint no such thing as a stupid question unless you dont ask it
