Hello Everybody, Does anyone have a piloted drill bit 3/8" x 1/4" they could loan to me? I need to drill aluminum with existing 1/4" holes and want to keep them concentric.
Thanks, Rick Caldwell

Hi Rick
Will drill bushings work?
I think our tool loan program has either the drill bushings or the drill bit you need.

Hi Robbie,
Bushings will help keep the bit square but I was looking for a piloted bit to stay concentric with the existing 1/4" holes. I can set up on the drill press multiple times as an alternative to using a piloted bit. I was just going for the fast, foolproof method if possible. Pan Am Tools had a min. order of six when I went to buy one this morning.
Thanks, Rick

Hey Rick
Let me dig around and see what I have. My drill bushings did exactly that. Made it so you can center the smaller drill on the larger hole.
I’ll check tomorrow. I know Dale (Bipbuilder) sent me some drill bits recently.

Ok, Sonex Builders. We have a builder in Maryland finishing a legacy Waiex kit and he needs to borrow piloted drill bits.
“1/4 to3/8 and 3/8 to .0375 I think. I’m listening to sonex flight podcast 51”
Who can help him please?

Hey all,
I’m building up the wing spars for my -B. Do we need these piloted bits for drilling the attach blocks and spar for mating or just when rigging the wings to the fuse?
Also, confirming these are the 2 needed to get the job done without having the hole wander or wallow out, misalign, etc,etc.
1/4 to 3/8 and then 3/8 to .0375 for the “tight fit hole”?
