From my reading, I understand that hand reamers (with the square end) are different from chucking reamers. The shape at the front end is different, to allow a straight start with the hand style. But beyond that, is there any practical difference? I don't see any reason that I can't (or shouldn't) chuck a hand reamer in a drill chuck or collet and use it under power. Am I missing something important?
