A fair while ago we were discussing as to why certain taper drills had the top end ground flat on opposite sides
I suggested that it might be to allow the manufacturing as polish /precision grinding the taper would be difficult ... found this tube video ...about 7 40 sec in.
But really IMO the whole video is worth looking at if you've got the time.
