AM-2 GENERAL PURPOSE POLISHING STONE
AM-2 is an excellent all around finishing stone. AM-2 is engineered for hand polishing all types of mold and die steels, including SAE 1030 pre-heat treated P-20, H-13, S-7 and T-420. Soft action combined with the perfect breakdown of AM-2 also permits pre-finishing on non-ferrous metals such as aluminum, beryllium, kirksite and high chrome/nickel stainless steel. Some polishers obtain excellent results using water when finishing kirksite.
