With the Norton 01 225X20X51 3SG 60 H12VXP grinding wheel, you achieve high precision and rapid stock removal on hardened steels and tool steels. The 3SG ceramic abrasive grain delivers aggressive cutting performance, while its self-sharpening microcrystalline structure fractures under pressure to expose fresh cutting edges, significantly reducing dressing frequency. Its porous vitrified vxp bond ensures cool cutting action, preventing heat build-up and thermal damage on delicate workpieces. Featuring an outer diameter of 225 mm, a thickness of 20 mm, and a 51 mm bore, this straight shape 01 wheel maintains form stability at speeds up to 45 M/S.
