I need to order some drill rod to make some reamers. Now for the questions.
I see there are water hardening,air hardening and oil hardening. Which is the best for machining and making the reamers? Read "EASIEST" ;D ;D ;D
I have never even seen drill rod before let alone work with it.
Which is the easiest to harden and temper?
If i'm going to use it in just cast iron, aluminum and brass do I even need to harden and temper it?
