Gesswein EDM Blue Finishing Stones

Made from premium aluminum oxide. EDM Blue is a harder formulation of our EDM Stones. These polishing stones are specially designed to handle the high-speed back-and-forth motion of a profiler or ultrasonic machine. Superior for removing the hardest EDM scale. Designed for use on hard surfaces at high speed while holding its shape.

  • Harder than our regular EDM Stones and designed to remove the tough, hard scale left by the EDM process.
  • Contain extra-sharp premium-grade aluminum oxide for fast cutting action plus a small amount of cobalt blue for added hardness.
  • Break down slowly and cut fast.
  • Maintains shape, saving you time.
  • Resist breakage and are specifically designed for use in reciprocating profilers.

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.
