Variable speed, 8in bench grinder

[Vinny]

How does it do on a HSS tool bit? The last inexpensive grinder I bought would almost come to a stop. I found an old 3 phase grinder on craigslist, added a static phase convertor and works great. Oh, one good thing that grinder was good for was to vibrate a mold. When I'd make something out of hi temp ceramic, the mold had to be vibrated to get the air pickets out. That cheap grinder was great for that!
