Right, this stuff is very hard.  Still, I cut tungsten welding elecrodes for 
my TIG welder to length by grinding a notch with my grinder (wheel corner) 
and snapping them.  Not much is wasted.  The ends shape easily on a standard 
grinding wheel and can be smoothed nicely on a rubber-bonded abrasive wheel 
(Cratex, etc.).  Chuck them in a drill motor to make a reasonably symmetrical 
radius if you have no lathe.

I never had occasion to drill or tap tungsten and expect that would be quite 
a challenge without the specialty tools.
