3-1/2 Inch Electroplated Diamond Core Drill
Crystalite's Brazed Diamond Core Drills are a solid steel shaft with a single layer of diamond electroplated onto the shaft. The brazing process makes for a harder, longer lasting electroplated bond so these drills will hold up well to consistent use, but once the diamond layer is gone they will need to be replaced. The drills can be used in either drill press or hand held drill while your piece must have either running water on it or be submerged for drilling.
