It's possible with a Dremel. For dies run a ball stone inside the chip
holes, for taps grind the wall of the gullet under the tapered cutting edge
with a cylindrical stone.
My surface grinder is a Delta Toolmaker, with a tilting and swiveling wheel
head that Prof. Chaddock may have copied:
The patent drawings are dated 1942. It isn't the best design for grinding
mirror-smooth surfaces, but it's versatile.
I don't have a sliding collet tool holder as nice as the Quorn's so I
regrind the taper of large second-hand taps between centers on a swivel
table. The resulting flat relief hasn't been a problem so far. It could be
done in two steps like an end mill to reduce the relief angle behind the
edge but still have clearance.
