High Speed Grinders vs. Low Speed Grinders

I love sharpening my lathe chisels on a grinder. It makes for fast sharpening, which means I can get back to my lathe turning quickly. When it comes to sharpening chisels, as opposed to shaping, a metal edge, a low rpm grinder offers a lot of advantages. There are uses for high speed grinders too, but it's very important to understand the applications and differences between each machine.
