I was sharpening my Crown 3/4" spindle gouge on a Slow speed grinder and I got the tip a little too hot so I stuck the first 2" of the gouge in some room temp water and "WHAM" the gouge turned a dull grey color. Does this mean that the temper (?) of the HSS steel has been affected? Thank you in advance for your help.


Never mind. Moderator please delete this post or close it. Thank you.

I think it's tough to destroy the temper of a HSS tool. I don't see the need to delete this post, Mike, as it's a good question...

Are you supposed to dip the tool in water after sharpening? I've never done that, mostly because I really dislike rust in my shop, and metal and water don't seem to like each other most times!

I read an article about heat and HSS metal. Because the temperature necessary to affect the temper of HSS is so high it is not necessary to quench the tip after grinding. You probably did nothing wrong to the metal.

Have read cool in water and not cool in water, let HSS air cool. I am good with air cooling, always strive to not get tool too hot while sharpening.

Thank you all for your help. I started double guessing myself on whether or not to ask the question.
