DutchLine - Diamond Core Drill M14 - 125mm

The DutchLine diamond core drill with M14 thread and a diameter of 125mm makes drilling extra-large openings through hard bathroom materials a manageable task. Use this drill to create generous apertures for large sanitary penetrations, ventilation grilles, or other installations requiring a substantial diameter. The impressive 125mm size has been specifically developed for professional applications where smaller drills fall short – such as fitting large-bore waste pipes or cutting inspection holes through existing walls.

The vacuum-brazed diamond segments on the cutting rim deliver consistent drilling power when working with ceramic tiles, granite, marble, porcelain, and reinforced concrete. The industrial-grade diamond grit reduces vibration during drilling and prevents chipping at the material edge. The open segment design efficiently removes slurry from the cutting zone, preventing overheating and significantly extending the drill's service life, even under intensive use.

The standardised M14 thread fits directly onto angle grinders and drilling machines with a corresponding spindle, with no adaptors required. For optimum results, we recommend wet drilling with a continuous water supply, particularly when working with ceramic and natural stone. The drill can be used in combination with a pilot bit for accurate positioning before boring the full hole. Use a machine with sufficient power and variable speed control for the best handling at this size.
