I have some 1" x 1" x 1/8" 304 stainless tube that we drilled 80 holes with a 13/32 drill, there are about 6 holes that my guy didn't press down hard enough with the hand feed drill press causing the bit to rub and not cut causing the material to work harden.
So I bought some drill bits from MSC, I talked to a tech team guy and he said they should do it, they didnt !!!, so then I bought 2 more that are even better at a cost of 20.00 ea.
So, before I ruin these, does any one have any ideas to take the work hardening out the steel, would heating it up and then putting it in my fiberglass blankets to cool slowly help.
