Sharpening wheel rotation direction.
Mar 8, 2010. #5. Grinder Wheel Rotation. As pointed out, grinders tend to rotate down toward the tool rest, keeping the tool on the rest. With this rotation the burr forms on top of the tool. This is due to the deformation of the edge on the unsupported top surface of the tool as the wheel moves into it.

What is the best grit for a grinding wheel
If you're sharpening turning tools, I'd tend to suggest a low heat wheel that's 120grit or above. You'll hopefully be using it primarilly to touch up and maintain edges and the higher the grit, the cleaner the edge. Don't throw out the old heavy grit wheel, though. It's handy for regrindings, shaping scrapers, lawnmower blades, etc.
