Great for making pulp (if you can't afford a Hollander beater), for mixing pigments into pulp or for remixing settled pigments. All stainless steel blades are most efficient type for mixing just about anything, even semi-solid masses that need reconstituting into liquid form again. For best results, choose the size that fits the volume of material to be mixed. These blades fit into a standard variable speed, electric hand drill. Make sure that the shaft size of blade you order will fit your drill.
