The Tuga Diamond Sanding Disc turns your wheel into a grinder. Peel the back, stick the 6 in electroplated diamond disc to a bat, and hold your piece against it while the wheel spins. The disc does the work, so you can flatten a foot or grind off a glaze drip in seconds instead of sanding it down by hand.

Use it on bisque or glaze-fired work to grind off glaze drips and kiln wash, level rough or uneven feet, and finish the bottom of a pot so it won't scratch the table. Work coarse to fine: start at 60 or 120 to remove material, then step up through the grits to a smooth surface.

Works wet or dry. A little water keeps the dust down and the grit cutting longer.

Care & keeping

Rinse under running water after each use to clear clay and glaze out of the grit. Let it air dry before you put it away. Store discs flat and apart so the grit faces don't rub against each other.
