I suggested (again) grinding the sides on the tapered the paddle bit. That
may not do anything but squeek. If you were intent, (not that crazy) you
may have to take a dremel tool, and grind a groove. Grind it on the face,
parallel to the side you tapered, again on the side that first touches as
the bit spins, so that the cutting chips curl around backward and break
off. It has to give the leading edge of the chip encouragement to separate,
or rip. It ain't rocket science. And the difference between failure and
success can be very minor indeed.

I use a spade bit, which I presume is the same, modified to the standard
taper taper for making the holes in candlesticks. 7/8 taper 3/4. Quick
grind job and a deburr was all it took.
