The Secret Of W186 Blue Mounted Points 3mm Shank (pkg. Of 200) Deluxe Edition [bkxFHvRK]

These superior quality blue mounted 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 (1-1/2" in length). 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 (380-1030).
