DiamondCore Rotary Tools have diamonds embedded all the way down to the shaft, not just on the outer edge. The 170 grit round tool is ideal for autographing or personalizing a high-fired piece. Use them on bisque, high-fired clay, glaze drips, porcelain, tile or glass. Quickly grind off off glaze drips, chipped feet or sharp edges. For longevity use water, high speed and gentle pressure. "Let the Diamonds do the work." 7mm diameter. Shaft diameter 1/8".
D9-80 grit ( coarse - grinding)
D10-170 grit (fine- for autographing)
Use all appropriate safety precautions. Keep out of the reach of children.
