Could try drilling the hole larger, running a dowel or a plug in it and drilling that out so it becomes a feature. If you predrill the plug, you will not have to worry about tear out in it. Drill your hole for the plug larger from both sides so you don't get more tear out than you already have.
good luck

: The choice of a different style of drill bit would also have prevented much
