I've managed to do this with a die grinder and cutoff wheel. Not the right
tool for the job, but it will work if you're careful. Like you're learning,
try to do the bulk of the material removal in the pedestal grinder freehand.
Putting a proper wheel in this grinder will help a bunch. With practice,
you'll have less than 10 thou to remove on the secondary relief. it won't
hurt a thing if the back part of the relief still shows free hand grind.
Then just do the cutting edge.


Might I suggest that if one has spare arbours for the surface grinder, a
cutoff wheel on the surface grinder might be the quickest solution.

Haven't done it yet myself, but it's on the to-do list for when the mill is up
and running.


For me, the ticket is to have a sharpening day once a year. Then do a bunch.
You can get dull end mills almost free on eBay etc. I now have several
hundred that I've sharpened.


Got to do that with the drill collection...
