I want to soften a broken end-mill so I can turn its shank to a combo pilot+countersink form, then re-harden it. The new tool will be used on/in wood for only about sixty holes so I guess it won't have to be fantastically hard.
I've tried heating to (fairly bright) red-heat and letting it cool but it is still far too hard.
Any suggestions, please?
