I picked up a set of Freud lathe tools from Craigs list and the steel is not HHS. It is stamped with Chrome Vanadium and with a little research i found out it is RC 50-60. So is that another way of saying High Speed Steel? I think the steel might be the same as bench chisels which means that i have to be carefull not to over heat the tip when grinding. Does anybody know the difference of the two steels? Oh ya the Freud model number is TT-108 they sold for around $100.00 when new. They are no longer made.

I’m not an expert on this but I think you should assume that you can overheat these tools. The good news is that you should be able to get a sharper edge on them. The bad news is that you will have to sharpen more often and be careful not to overheat them. Dip them in a water bath frequently when sharpening.
