I like to make knives & tools out of scrap steel, so I can’t really get rid of my $10 pawn-shop-find 3450×6”. So for tool sharpening & fine work I made a mod to my grinder. I in-line wired a ceiling-fan dimmer switch rated for the same amps as my grinder and set the switch’s internal control at its lowest setting. Works GREAT! At first, the speed was drifting up or down from the grinder’s vibration, and then I mounted the switch farther away from the grinder and it stays at the speed I set it.
Oh…to answer your question, I use an 8” 120 grit white wheel for sharpening. I bought a 90 cent brass bushing and jb welded it into the arbor-hole so that it fits on my grinder’s 1/2” arbor shaft.
