How does one get a left handed flute out of a right handed bit? Even if

I wuz gonna ask that too.
But, I imagine you can grind the cutting edges so they'll work, but the
flutes sure won't wanna move the chips up out of the hole, will they?

The bit is only intended to catch hold of the broken bolt with a
reversible drill motor and twist the broken bolt out of the hole. The
flute at the end is ground to cut at a low angle to catch the bolt and
remove it. You can drill a small pilot hole in the center of a stubborn
bolt for the left hand sharpened tip to catch. Done it for years prior to
retiring. Use the method still if needed.
Don't need it as often, that's all.
