The 4-piece XS-CASE from Einhell contains four hard ceramic drill bits with an extremely hard, high-temperature brazed carbide plate for drilling into tiles. Thanks to the special grinding of the carbide plate, the tile drill bits are made for hard tiles such as porcelain stoneware, as they are equipped with particularly sharp cutting edges. A pronounced centre point enables precise drilling without slipping on the workpiece. The tile drill bit set made of robust, sandblasted tool steel is particularly suitable for working on marble, extremely hard porcelain stoneware, roof tiles, wall and floor tiles and granite. It is ideal for renovation work in the DIY sector, but also for professional use by pavers and tilers. Thanks to the E 6.3 shank, the tile drills for porcelain stoneware are compatible with all standard drill chucks and bit holders in commercially available cordless screwdrivers and drills. The milled hexagonal shank prevents slipping in the drill chuck. When using the ceramic drill bits, we recommend using them without impact, with high contact pressure in first gear and a maximum speed of 400 revolutions per minute to prevent overheating. After drilling through the material, it is advisable to switch to the correct drill bit for the substrate material, such as a concrete or masonry drill bit. The tool set is supplied in a practical storage box with a robust auto-lock clip closure and transparent lid.
