Read full description

The DutchLine Diamond Core Drill Bit M14 with a diameter of 40mm has been specially developed for accurately drilling holes in hard materials such as ceramic tiles, porcelain, natural stone and concrete. With this professional drill bit, you can effortlessly create openings for pipes, waste outlets or mounting brackets in your bathroom or wet room. The 40mm diameter makes this tool particularly well suited for medium to larger penetrations where precision and a clean finish are essential.

The drill bit features a high-quality diamond coating that provides superior hardness and wear resistance throughout the drilling process. This diamond layer remains effective even during intensive use on extra-hard stone types. Wet cooling during drilling is recommended to significantly extend the service life of the bit and prevent overheating. The robust construction guarantees a long service life, even with frequent professional use.

Thanks to the M14 thread, the diamond core drill bit is compatible with virtually all common angle grinders and drill machines with an M14 connection. Fitting is quick and tool-free, so you can get started straight away. The bit can be used both dry and wet, with wet drilling recommended for optimum results and longer service life. Combine this diamond core drill bit with other DutchLine tools for a complete tool set for your bathroom project.
