So umm... stupid question. I have a Hario slim hand ceramic burr grinder, but before I got the electric burr grinder, at times I didn't like turning the crank. So I attached my drill to turn it on a slowish pace (10-20% drill speed?) to grind.
Is this going to damage my grinder in the long run vs using the hand crank? I didn't dare just use the drill at full speed in case I wrecked the burrs doing so.
