These superior quality stones are made of Aluminum Oxide bonded with porcelain type clays which provide the greatest strength and rigidity required for fast stock removal and longer life. The ceramic bond controls the release of the Aluminum Oxide abrasive grains so that as each particle begins to dull, the bond discharges it allowing new abrasive grain to surface with fresh, sharp cutting edges. Guaranteed to run true. Stones are securely bonded to 3mm" shanks. Also available on 1/8" and 3/32" shanks (see Related Products).

Our Blue Mounted Stones are hard stones which hold their shape exceptionally well and are recommended for use on hardened steel. All are 120 grit (fine). Aluminum Oxide with Cobalt added to provide lubrication while grinding. Cut well and leave a smooth surface.

  • Can be dressed with our Tru-Stone, see "Related Products" below.
  • Mounted on 1-1/2" long nickel-plated steel shanks (3mm diameter).
  • Sold in boxes of 12, 36 or 72. See "Size Chart" tab above for details on each stone.

Before using any abrasive product, follow all safe operating guidelines with respect to eye protection, hand protection, hearing protection and respiratory protection. Also read the Material Safety Data Sheet to be aware of any inherent hazards or cautions.

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.
