What direction of grinder rotation

[Bryan Milham]

As the title says 'What direction of grinder rotation'.

It might sound like a strange question but does the direction the wheel rotates, with respect to the tool, make any difference?

To explain;

My Dry Grinder rotates onto the tip of my tool, abrading from the tip to the heel of the bevel angle.

My Wet wheel however I use from the other side, such that it abrades from the heel to the tip of the bevel angle.

Usually the wet grinders can be used backwards because they also have a leather honing wheel, which must be used running away from the edge. You can use the solid wheels, (stone, diamond, cbn etc.) in either direction.

I have an old grinder I converted to a honing machine by reversing the motor and switching the stone wheels for felt wheels.

I prefer grinders that turn away from you,my homemade dry 8" slow grinder can rotate in both directions,but seems to leave a better edge when rotating away.

With a traditional grinding wheel running away, you wouldn't get a fine wire-edge on the top of a scraper!
