A 3/8 shank will fit in the braces. The part number we use at Nationals is the Lenox Tools 1779805 6L arbor. This arbor is a quick change arbor, It has a 3/8 shank and a bit that is approximately 3.25. There are other manufacturers available as well.

Please note that at Nationals, most of our bit braces have been welded so that the shank cannot be removed from the brace, but this is not required.
