I think we are talking at crossed-purposes.
Entirely possible, Andy. And I still haven't checked, got side tracked trying to grind a tool, and I think I've wasted my time, burning up a 5/16" piece of tool steel because the alox wheel got dull and heated it up to bright red, several times. I cleaned a dressed the wheel several times, and it wound up exploding while just spinning free. And I am not at all sure a .0485" wide tool with a .200 stickout, will survive makeing threads .075" deep in SS. I don't figure on any more than 5 thou per pass. And a tool I could shave with. I need a tool grinder but I can't see the $750-$850 for a well equipt one with a diamond cup wheel. Dremel makes a nice disk, but the %$#@^@& mandrel and disk are special, and flex like cooked spaghetti. I've got 2 of them stacked for improved rigidity but the dremels lowest speed still ablates the diamond in just a few minutes run time. And they are $20 a disk! Sigh...
