Diamond core drill bit 22mm for porcelain stoneware with centering drill Kranz KR-92-0007

Diamond core drill bit with a diameter of 22 mm is used for drilling porcelain stoneware, ceramics, and glass. The presence of a centering drill bit ensures precise positioning of the core bit on the surface and helps prevent displacement during work. The coating of the diamond core bit is applied using a two-layer galvanic method, which ensures efficient drilling and a long service life of the tool. The uniform distribution of diamonds along the cutting edge guarantees neat drilling of the material without cracks or chips. A diamond layer height of 6 mm provides high performance, and the three-sided shank ensures reliable fixation in the chuck. When using diamond core bits for drilling holes, cooling is required, which is achieved by supplying water to the working area.
