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.

For recommended speeds, consult the American National Standard Institute for full information on vitrified mounted wheels. Before using any abrasive product, follow all safe operating guidelines with respect to personal protective devices including safety glasses. Also read the Material Safety Data Sheet (MSDS) to be aware of any inherent hazards or cautions.
