"I have to politely disagree. Having removed and installed a couple of thousand ejector roll pins in my time, I can assure you that dressing a roll pin is unnecessary. Having an good ejector tool and a quality pin and starter punch set is all you need.
That being said, I am not aware of a drill motor that has a chuck that will hold a 1/16 roll pin that is only 3/8 of an inch long. Most chucks will not grab something that small in diameter unless it is nearing an inch in length."
OK...
