Once I turn the handle and drill a correct size hole on drill press, I put the handle in a vise (wooden jaws) and "tap" the tool in with a wooden mallet. Once you have it started an inch or so, you can hold a block of wood on the tool and strike that until it seats. Also, once the tool is started, you can take it out of the vise, invert it, hold it firmly by the handle, and strike downwards on a piece of wood or bench. A little soap on the shank will help it slid in more easily. Not too scientific, but I've done several this way with no problem. Just don't strike the handle end - it might split.
