Well, that is exactly I did for my other props. Drill with a 10mm standard drill bit on a press. The only drawback is that the bit will not center on the existing hole unless the prop is allowed to move a little bit at the very early stage. It becomes dangerous as the prop is hold by hand and the drilling could complete the entire length of the hub in a fraction of a second. The prop is basically pulled up instantly and can cut the fingers.

With a reamer, the centering is guaranteed and you just need to push the press handler down very slowly. The prop can be secured on a drill jug.
