High quality materials of consistent hardness. Various shapes for the widest possible range of applications. For grinding and chiseling hard materials such as cast iron, cast steel, malleable cast iron as well as hard metal alloys and refined steel. Accurately dimensioned shafts of 2.35 or 3mm (Ø 3/32" or 7/64") ensure maximum concentricity. Grinding rule: soft materials = hard grinding bits; hard materials = soft grinding bits!
