  • Cuts faster due to the sharpness, hardness, and friability of the abrasive grain.
  • This stone is used for ductile metals; ideal for softer tool steels and non-ferrous metals.
  • Hard and Soft tool steels as lows as Rockwell C 25, and soft non-ferrous metals such as Aluminum and Beryllium.

Important: Abrasive stones break down during mold and die polishing, grinding, tool sharpening, and dressing of cutting & grinding wheels. The resulting dust is classified by OSHA as inert or nuisance dust. Please consult the Material Safety Data Sheet for each stone; data provided therein pertains primarily to the dust produced during and after use. Please note that hazards may change when abrasive stones are used in conjunction with solvents, cutting fluids or other chemicals.
