Self Centering Drill Bits

Could you temporarily mount your e-track parallel to, but offset from (say 1") the e-track's permanent position. Then make a jig with a 3/8 stub for the etrack holes and with a 5/16 drilling hole offset 1" from the 3/8 stub?

Vix Bits, not Vex. Vix Manufacturing company. I think it was patented a long time ago but long since expired so many people make them now.
Your right, thanks for the spelling error alert.
I made the edit before time expired.

OK, the lessons learned post. I got the drill bit centered up on the countersunk holes by using flair nut coupling fittings, and a bit the just barely fit through the inner hole of the fitting. Then used that hole as a pilot for the larger drill bit.

Another reason to buy an assortment of drill bushings and a 3D printer. The ability to make custom jigs which do what I want accurately.
