The diamond-coated "Ceramic" drill bit is the ideal solution if you want to prepare sanitary and electrical installations on or through tiles with a cordless screwdriver. It enables you to drill precise holes in all types of wall and floor tiles with a cutting depth of 45 mm. It is available in various diameters, so you will find the right drill bit for every project. It can be quickly locked in the drill chuck of your cordless screwdriver using the round shank (Ø 10 mm). With the integrated centring drill bit, you can position the hole with pinpoint accuracy. After drilling, it can be removed without tools so that you can continue drilling quickly. The base body of this drill bit is turned from solid material and is set with high-quality industrial diamonds. It offers a long service life and high precision. A water sponge is integrated into the core bit to protect the diamond coating. It must be soaked with water before use, which is squeezed out during drilling and provides the necessary cooling. At the same time, the water binds the dust. The drill bit is TÜV-certified - so you can rely on a safe, high-quality product.
