The diamond-coated "Ceramic" drill crown is the ideal solution for preparing plumbing and electrical installations on or through tiles or ceramics with a cordless drill. It allows you to achieve precise drilling in wall and floor tiles of all kinds with a cutting depth of 45 mm. Available in various diameters, you can find the right drill crown for every project. It can be quickly secured in the chuck of your cordless drill via the round shank (Ø 10 mm). The integrated centering drill allows you to position the hole accurately. After starting the hole, it can be removed without tools, enabling you to continue drilling quickly. The base body of this drill crown is made from solid material and is embedded with high-quality industrial diamonds, providing high durability and precision. To protect the diamond coating, a water sponge is integrated into the drill crown. It must be soaked with water before use, which is then squeezed out during drilling to provide necessary cooling. At the same time, the water binds the dust. The drill crown is TÜV-certified, ensuring you are using a safe quality product.
