14 mm Diamond Drill Bit with M10 Thread for Angle Grinder Soldered Diamond Black Dry Drilling for Tiles, Marble, Granite and Glass
You already have the maximum available quantity in your cart.
The diamond drill bit with a diameter of 14 mm is designed for drilling holes in hard construction materials using an angle grinder. It features an internal thread M10 on the clamping side, allowing it to be screwed directly onto the spindle of the grinder without a chuck or additional adapters. The cutting part is covered with soldered diamond grains, which can handle ceramic tiles, cladding, sintered tiles, marble, granite, concrete, and glass. The diameter of 14 mm indicates the size of the hole that will be created after drilling, so please choose the diameter according to the pipe or element that will pass through the hole. The drill bit is intended for dry drilling, without the need to add water. It is suitable for holes for dowels, anchors, cables, and thin conduits in cladding and tiles, and will be useful for tilers, plumbers, and DIY enthusiasts during bathroom or kitchen renovations.

- Colour – black.
- Package Contents – 1 piece of 14 mm diamond drill bit.
When drilling, hold the grinder at an angle of approximately 45 degrees and carefully create a shallow groove in the surface in the shape of a crescent. Once the drill bit catches, gradually straighten the grinder to a vertical position of 90 degrees and drill with light pressure. This procedure will prevent slipping on the smooth glaze and keep the edge of the hole clean. Allow the drill bit to work under the weight of the machine and do not apply excessive force to prevent the diamond layer from overheating unnecessarily. Before the first use, ensure that the drill bit is securely tightened on the spindle and that the grinder runs without vibrations or wobbling. During prolonged drilling, take short breaks; you may also cool the cutting part with water, which will extend the tool's lifespan. Use protective goggles, gloves, and a respirator, as fine dust is generated during dry drilling.
The 14 mm diamond drill bit with M10 thread is a practical addition to any angle grinder. Thanks to the soldered diamond, it can handle hard tiles and natural stone, creating a clean hole without chipped edges. It is suitable for work on construction sites as well as at home, where you need to quickly make holes for dowels, anchors, cables, and thin conduits in cladding and tiles. The attachment to the M10 angle grinder is quick, and the drill bit can be easily replaced with another diameter. The tool is compact, making it easy to store in a toolbox, and you always have it on hand. Dry drilling saves time, as you do not need to prepare water or cooling. The result is precise holes in tiles, marble, and granite without the need to purchase an expensive core drilling machine.
