Collection: Gesswein® Moldmaker Stones

Moldmaker Polishing Stones are crafted for polishing softer tool steels and non-ferrous metals with speed and efficiency. Made with a harder black silicon carbide abrasive, these stones break down quickly to expose fresh, sharp cutting edges—making them ideal for fast stock removal and precision finishing. Their friability and sharp grain structure give them superior cutting performance on materials like aluminum, beryllium, and tool steels as soft as Rockwell C 25. Made in the USA, Moldmaker Stones reflect our commitment to quality and craftsmanship for demanding mold and die work.
