I have some drill bits that as far as I know have only been used in a hand-powered drill. They are at least 15 years old, maximum 40 years.
Can I use them in an electric/power drill? If the answer is "it depends", is there some way to tell? And if I get it wrong and something bad happens, will that bad thing be disastrous, or merely cause damage to the bit? (i.e. if the answer is that the bit might shatter and blow up the drill and I'm shrapneled with little pieces of metal, I won't try it...)
If this seems like an stupid question - my idea is that the metal might not be hard enough or something to stand up to the greater strain/pressure/speed/??, but I don't know if that is a thing.
