DutchLine - Diamond Core Drill M14 - 20mm

The DutchLine diamond core drill with M14 connection and 20mm diameter makes drilling precise holes in ceramic tiles, natural stone and porcelain a straightforward task. This professional tool has been specially developed for creating penetrations for pipes, taps or shower hoses in bathroom walls and floors. The compact 20mm diameter offers the perfect size for standard water pipes and plumbing connections, with the diamond coating ensuring a clean and accurate result without cracking or chipping the material.

The drill features a high-quality diamond coating applied evenly across the cutting edge, ensuring optimum contact with the material during drilling. These industrial diamond particles are durably embedded in a metal matrix layer, resulting in excellent wear resistance and a long operational lifespan. The open structure of the cutting edge effectively removes drilling slurry, preventing overheating and significantly extending the service life of the drill, even during intensive use in hard stone types.

The universal M14 thread ensures quick and secure attachment to common angle grinders and drill machines with an M14 spindle. Fitting requires no additional tools and is completed within seconds by simply screwing on. For optimum results, we recommend wet drilling with water cooling, which improves cutting performance and minimises dust. The drill is suitable for hand drilling in tiles up to 12mm thick and can be combined with other DutchLine diamond tools for complete bathroom installations.
