Just drill the hole nearly to depth with a standard drill and finish to full depth with the flat bottom drill. They are super easy to make. Just grind them square on the belt sander and relieve them on the bench grinder.

I've made a few flat bottom drills, using a belt grinder, having various results, probably due to haste on my part.

I have one of the Australian designed (maybe built) Jancy RadiusMasters, a 2" x 48" belt grinder, a vary versatile machine.
