166 forum posts	I have a dremel type mini grinder. I use it either to grind surfaces ,like cleaning up a casting or to clean up the egde of thin sheet. I just cut some 1.2 mm SS sheet. Do you perfer the sanding drums or to use a stone? I find that the stones i use are very soft and wear away quickly. Does anyone have good results with the tiny milling cutters type? Mike

But I am cleaning up the inside edge of holes on sheet steel, Linisher will not work.
