  I might first ask, what material are you trying to drill and tap? Stainless, high alloy steel, aluminum, brass? The size and quality of the drill will depend on that.

  Interesting my freebe TRW Greenfield plastic tap chart also lists #21 or 0.1950 for use with a 10-32 having the threads being 68%.
