It's just a 2" X 72" belt grinder. I use it for initial bevel grinds on molding plane irons, knife making, regrinding vintage chisels/irons, sanding plane wedges (wooden) as well as a lot of other things. It has the flat platten shown, but I also have a 10" wheel, and small diameter grinding wheels from 1/2" up to 1.5" diameter. Great for inside curves. I use it for roughing out wood parts as well, with belts ranging from 36 grit up to 800 grit, and several different scotchbrite belts for polishing metal parts, too. 2 hp 3 phase motor, run with a VFD, for infinite speed control.
