Gesswein EDM Finishing Stones

Remove the tough, hard scale left by the Electrical Discharge Machining process much faster than any of our other polishing stones.

  • Contain extra-sharp premium-grade aluminum oxide for fast cutting action.
  • Special clay bond so they hold their shape well for working small details and sharp corners.
  • Break down slowly, cut fast and resist loading.
  • Yield excellent results by hand and even better in a profiler or ultrasonic polisher.

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. For more complete information, consult the Material Safety Data Sheets of chemical products used with abrasive stone products.
