Yes it can be a challenge for mere humans to get a tap to go in straight. Wherever possible I chuck it in my pillar drill and set the workpiece level beneath it, then turn the drill chuck by hand. Obviously no good for in-situ repairs.
Others have described threading a nut on the tap first to provide at least a small square contact face.
Parazine, yes brass by all means. But I had a case last year which had been done in steel and it is then very hard to repair once the steel inserts go bad.
