Product never used, packaging damaged during transport. Unopened product, 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 6 mm yellow cemented carbide bit (pre-drilled) and tile drill bits of 5 mm, 1 x 6 mm, 1 x 8 mm, 1 x 10 mm and 1 x 12 mm. NOTE: The yellow (pre-drilled) drill bit 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. To drill efficiently and beautifully, it is necessary to replace the blue drill bit after using the yellow one to extend the life of the 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 material surface. 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 offer a fast and durable drilling effect. The blue diamond core 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.
