Set of 10 Diamond Core Drills 3–50 mm Diamond Coated Drill Bits for Glass, Tiles, Ceramics and Granite Silver for Drilling Holes
You already have the maximum available quantity in your cart.
This set of ten diamond core drills is a practical tool for anyone needing to drill precise holes in hard and brittle materials. The bits feature a cutting section with a diamond coating, which can handle ceramic tiles, glazed paving, untempered glass, granite, and other types of stone. The set covers diameters from 3 to 50 mm, so you will find the right size for small holes for plugs as well as larger openings for pipes, cables, or taps. The core drills fit into a standard drill chuck and are suitable for DIY enthusiasts and tradespeople alike. They are ideal for tiling bathrooms and kitchens, modifying glass shelves, or creating decorations and pots from ceramics.
Each core drill has a cylindrical shank and a hollow metal casing in silver colour. Smaller diameters have the shape of a slender tubular drill, while larger core drills feature a wide casing with a side groove, allowing for easy removal of the cut-out disc of material. The diamond grit is medium, which enables even grinding without excessive pressure on the material. The largest core drill with a diameter of 50 mm can handle a waste hole for a sink or a grommet, while the smallest is used for fine pre-drilling.

For the long life of the core drills, it is important to drill wet. First, clean the surface of the material, moisten it with water, and mark the drilling spot. Start drilling with the core drill inclined at approximately 45 degrees to create a groove and prevent the drill from slipping, then slowly straighten it to a vertical position. Work at low speeds and without excessive pressure, continuously cool the drill with water, and just before breaking through, slow down to prevent chipping the edge of the hole. After use, rinse the core drills and allow them to dry.
This set of diamond core drills offers ten diameters in one place, so you do not have to search for individual bits for each task. They are suitable for installing taps, holders, and sockets in tiles, drilling glass panels, and creating drainage holes in ceramic pots. The cutting section with diamond coating grinds hard material cleanly and precisely. Thanks to the cylindrical shank, the core drills can be used with a standard drill you have at home. It is a practical addition to your workshop and tool kit for tiling.
