Diamond drill bit 14mm for porcelain stoneware, ceramics and glass Kranz KR-92-0025

Diamond drill bit diameter 14 mm is designed for working with porcelain stoneware, ceramics, and glass. It is a tubular drill bit made in the form of a hollow cylinder. Used in conjunction with drills or screwdrivers. The cylindrical shank facilitates reliable fastening of the drill bit in the chuck. The cutting edge is coated with high-hardness industrial diamonds, ensuring precise and clean drilling of holes without cracks or chips on the material surface. To prevent overheating during the drilling process, diamond drill bits must be constantly cooled with water. In case of overheating, diamonds easily detach from the base, so drilling must be performed at low speeds.
