About this item

Made from high-strength carbon steel with a smooth nickel-plated surface, the glass drill bit reduces resistance to a minimum, making it easy to drill precise holes in seconds. - Diamond Drill Bits Start the hole diagonally, make a round weave and then hold the drill straight. Water is required for lubrication during drilling. - Suitable for drilling holes in Glass, Tile Bottles, Blocks Jars, Fibreglass Porcelain Tile Ceramics, Slate Mable, Granite Light Stone (especially for Glass AND Tile). - Each diamond hole saw has been processed with a smooth and accurate finish, which lowers the cutting resistance and drilling pressure, and increases the sharpness and the use of water lubrication.
