Starrett DTDG01 Diamond Tile Drilling Instructions Drill Cutting for 5 mm 12

Made of sturdy plastic with guides for 5mm, 6mm, 6.5mm, 8mm, 10mm and 12mm diamond tile drills. "Rubber feet" prevent the guide from slipping when held against the tile. O-rings behind each hole in the guide ensure that splashing water is collected at the front of the guide and the tile drill is cooled. All tile drill bits and diamond hole saws need to be cooled with water throughout the cut to ensure maximum product life. We recommend using the tile drill guide only at the beginning of the cut and remove it once the cut is finished. Package Dimensions :19.0 L x 3.4 H x 9.2 W (centimeters)
