That's precisely how I sharpen my drills (and take a ton of flak for it on YT). It's called multi-faceted drill point geometry, and it works great. The traditionalists want to see conical relief on the secondary because they claim it can tolerate more heat, which is true, but the way I (we) sharpen them actually produces less heat, so there is less to tolerate.
Nice job on the fixture.
