Diamond core drill bit 65mm with centering drill Kranz KR-92-0017

Diamond core drill bit with a diameter of 65 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. The 6 mm diamond layer height 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.
