Product never used, packaging damaged during transport. Unopened, repackaged in our warehouses, in perfect working order, warranty available. Offers a set of diamond tile drill bits, consisting of 6 tile drill bits, including one 6mm yellow cemented carbide bit (pre-drilled) and tile drill bits of 5mm, 6mm, 8mm, 10mm, and 12mm. NOTE: The yellow drill bit (pre-drilled) can only be used as an auxiliary tool for pre-drilling and should not be used for extended periods, otherwise it will be easily damaged. For efficient and beautiful drilling, it is necessary to replace the blue drill bit after using the yellow one to prolong the life of the drill bits and improve efficiency. HOW TO USE: The procedure involves first installing the yellow drill bit on the hand drill, tilting it at a 45-degree angle and rotating it rapidly across the surface of the material. Then, replace it with the appropriately sized blue diamond drill bit and easily drill through the material. It is recommended to add water during drilling to cool the drill bit and extend its lifespan. These drill bits are suitable for materials such as tile, glass, granite, and marble, and provide a fast and durable drilling effect. The blue diamond core drill bit contains a cooling wax which, thanks to its wax structure, can automatically absorb and dissipate heat. The diamond tile drill bit has a circular handle and is suitable for many machines, such as hand drills, angle grinders, and bench drills.
