Diamond core bit 68mm with pilot drill Kranz KR-92-0018

Diamond core drill bit with a diameter of 68 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. Uniform distribution of diamonds along the cutting edge guarantees neat drilling of the material without cracks or chips. A 6 mm diamond layer height provides high performance, and the triangular 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.
