Equally important as the skill of grinding lathe cutting tools, is the ability to quickly and correctly sharpen a drill bit on the grinder.
If you don’t know how to do it, look through these links, grab some dull drills and start practicing. You know you’ve done it right when the tool cuts easily, produces two, equally formed, curly chips, and makes the correct size hole. With practice, sharpening can be done by hand in just a couple minutes or less.

This guy has the right idea – quick and simple: http://youtu.be/DGibYeprpkk However, I want to point out his safety mistakes. I don't really like to see him wearing a loose watch at that grinder, nor do I like to see him keeping the rag and tools on top of it.
This is how NOT to sharpen drills: http://youtu.be/pW7kGFcM2sc This method probably works, but is not the industry standard. You can tell by the comments how unacceptable it is to some.
