DiamondCore D11/D12 Slim Cone Rotary Tool
DiamondCore Rotary Tools have diamonds embedded all the way down to the shaft, not just on the outer edge. Use them on bisque, high-fired clay, glaze drips, porcelain, tile or glass. Quickly grind off glaze drips, chipped feet or sharp edges. For longevity use water, high speed and gentle pressure. "Let the Diamonds do the work." 4mm diameter x 15mm length. Shaft diameter 1/8".
