I have a chance to be the only distributor in Canada for a common brand of Grinder wheels of course minimum order is ten each soooo Contact wheel diameter preferred is: available on serrated and smooth 2" 3" 4" 6" 8" 10" 12" 14" Import and duty is likely high but the starting price is real good. they also carry drive wheels and idler wheels as well as the small contact wheels for choils and such
