Diamond Drill Bit 12 mm with M10 Thread for Angle Grinder Sintered Diamond Black Dry Drilling into Tiles, Marble, Granite and Glass
You already have the maximum available quantity in your cart.
The diamond drill bit with a diameter of 12 mm is designed for drilling holes into hard building materials using an angle grinder. It has 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 sintered diamond grains, which can handle ceramic tiles, cladding, porcelain tiles, marble, granite, concrete, and glass. The diameter of 12 mm indicates the size of the hole that will be created after drilling, so please select 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 used by tilers, plumbers, and DIY enthusiasts during bathroom or kitchen renovations.

When drilling, hold the grinder initially 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 avoid overheating the diamond layer. Before the first use, check 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, or you can cool the cutting part with water, which will extend the tool's life. Use protective glasses, gloves, and a respirator, as fine dust is generated during dry drilling.
The 12 mm diamond drill bit with M10 thread is a practical addition to any angle grinder. Thanks to the sintered 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 angle grinder M10 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 always have on hand. Dry drilling saves time as there is no 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.
