I've searched this site and others on the internet for some tempering charts for the most common used steels and so far I've found one for O1 and one for 5160. Now my problem is that there's several tables for a given steel our there, so which is correct?

Can someone tell me if these tables are correct?

The thing is, without a hardness tester to tell you whether your steel got full hard in the first place, it's all a bit of a SWAG anyway. Those look in the right ballpark, but rather than get hung up too much on a number that may or may not be accurate in your case, your best bet is just to test the tool and see if it performs the way you want. Unless you have a hardness tester, of course. :)
