DutchLine - Diamond Core Drill M14 - 70mm

The DutchLine Diamond Core Drill M14 with a 70mm diameter delivers professional drilling capacity for large-scale penetrations in ceramic tiles, natural stone and porcelain. Its generous diameter makes this drill bit specifically designed for creating larger openings — for example for pipework, ventilation grilles or plumbing connections in bathroom walls. The combination of size and precision makes this drill bit a reliable choice for renovation and new-build projects where accurate sizing is essential.

The cutting edge features a high-quality diamond coating that ensures effective cutting performance, even during intensive use on hard surfaces. The layered diamond material stays sharp throughout the drilling process and minimises wear, resulting in consistent drilling quality. The robust metal core absorbs vibration and provides stability during use, producing a clean and precise hole without unnecessary edge damage.

Thanks to the M14 thread, this diamond core drill fits seamlessly onto most standard angle grinders and drilling machines compatible with this universal fixing system. Mounting is quick and secure, with no additional adapters or tools required. When in use, it is recommended to use water as a coolant — this significantly extends the life of the drill bit and prevents overheating. The 70mm diameter makes this drill bit suitable for applications where larger openings are required than standard sizes provide.
