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.
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.
The Yard Store has these and many others 1/4 x 3/8 double margin bit $10
