Diamond core drill bits are specialized drilling tools used in the glass and ceramics industry to create holes in hard materials.They are equipped with diamond-impregnated segments or cutting elements made of industrial diamonds, providing high cutting performance and durability. Diamond core drill bits come in various diameters and lengths, depending on the requirements of the specific application. They are used in conjunction with dedicated core drilling machines that are equipped with a drill stand to allow for precise and clean drilling. The core drill bits are typically cooled with water to reduce heat buildup during the drilling process and extend the life of the drill bit. Can be made in a length 75 or 89 mm with a G 1/2 thread or straight shank. Standard wall thickness is 1,1 mm and grit size D181. Cooling by water or emulsion is required.
