Ksvet06 Posted January 4, 2018 Report Share Posted January 4, 2018 I know there are 2 different type of bench grinders. High speed and low speed. Plus jigs to get the correct angles. Are you able to sharpen on a high speed bench grinder too? Quote Link to comment Share on other sites More sharing options...
HandyDan Posted January 4, 2018 Report Share Posted January 4, 2018 Yes you can just be careful to use a light touch. Reshaping a tool is best done on the slow speed grinder. p_toad and kmealy 2 Quote Link to comment Share on other sites More sharing options...
lew Posted January 4, 2018 Report Share Posted January 4, 2018 Keep a container (ex: plastic butter tub) of water near by. Dip the tip of the tool into it about every pass over the wheel. It will help keep the metal cool. HARO50 1 Quote Link to comment Share on other sites More sharing options...
Gerald Posted January 4, 2018 Report Share Posted January 4, 2018 If you use CBN wheels the thoughts now are that it does not make a =difference. A light touch is best when sharpening as unlike reshaping you are only removing a small amount of metal . Cooling with water I will have to disagree with Lew on this as with HSS which most modern steels for turning are that or better and cooling is not needed , even if the steel turns blue the temper is not affected.

I cool any steel while reshaping because sometimes it gets too hot to hold. For touching up a dull edge I see no need to cool it. I can get it hotter using it.
