General description High-quality, temperature-resistant diamond grain for efficient and clean holes. This set of diamond drill bits is filled with cooling wax and is suitable for dry drilling. It is designed for a longer service life, with the use of water or coolant recommended. The drill bits can be used on various materials including glass, ceramic tiles, hard tiles, porcelain, granite, marble, quartz, limestone, fiberglass, terrazzo, porcelain stoneware, masonry, and stoneware. Technical specifications Drill diameters: Ø 6 mm, 8 mm, 10 mm, 12 mm Hexagonal shank: 7 mm Total length of the drill: 65-80 mm Installation Create a starting notch with the included carbide drill. Insert the diamond drill at an angle of approximately 50° onto the starting notch. Rotate 45° and drill carefully. Once the notch is deeper, place the machine and diamond drill bit upright. When drilling, make slight circular movements to remove dust and dirt. Pause the drilling process to cool the diamond drill bit and material at regular intervals. Repeat the previous steps until the hole is finished. Always clean the diamond drill bit after use and remove any residue. Usage Cordless screwdrivers require a speed of at least 1600 rpm. For electric drills, a speed of over 2000-3000 rpm is recommended. Using machines with low power and lower speed will significantly shorten the life of the drill.
