Problem with those auger bits is all of them I have seen have the
lead screw. That has ruined numerous attempts at this.

Ship'a augers are designed specifically to remain centered when
drilling deep holes; however, made the assumption this was a thru hole
not a blind hole.

If blind, no way, have never seen them much longer than about 21"-24"
long.

If thru, then half way from each end.

If cost is a consideration, making two pieces and gluing together will
use lower total cost tools.

Have fun.
