DutchLine - Diamond Core Drill M14 - 50mm

The DutchLine Diamond Core Drill M14 with a 50mm diameter delivers precise holes in hard materials such as ceramic tiles, porcelain, natural stone and concrete. This core drill has been specifically developed for creating penetrations for pipework, radiator valves or larger plumbing connections in your bathroom. Thanks to the generous 50mm diameter, you can effortlessly drill through tiled and stone surfaces for thick-walled pipes and large waste outlets without causing breakage or ragged edges.

The cutting edge features a premium diamond coating that provides superior hardness and wear resistance. This coating stays sharp even during intensive use on the hardest natural stone and glazed tiles. The robust steel core ensures stability throughout the drilling process and prevents vibration, resulting in a perfectly circular bore. With the ideal balance between cutting power and durability, this drill consistently delivers professional results, project after project.

The standardised M14 thread fits virtually all common angle grinders and drill machines with an M14 connection, so you can get straight to work without an adapter. For best results, wet drilling with water cooling is recommended, which extends the life of the diamond segments and minimises dust. The drill is suitable for both hand-held use and use with a drill stand for added precision on vertical bores.

The diamond core drill is supplied as a single unit, ready for immediate fitting to your existing tools.
