If you grind High Speed Steel you need to consider a CBN wheel. It grinds VERY fast with very little heat build up. I have a youtube channel and posted a video of a grinder I made for a cheap CBN wheel I bought on ebay. Honestly the grinder and wheel is not the most logical choice but I had a spare motor and all the materials and I got the wheel (60 grit) for $23 bucks so it was a cheap way to try the CBN. I was shocked and amazed! Very aggressive fast cutting and very little heat build up.
