Overview
Diamond Core Drill Bit 30 mm with M10 Thread for Angle Grinder Soldered Diamond Black Dry Drilling into Tiles Marble Granite and Glass

The diamond core drill bit with a diameter of 30 mm is designed for drilling holes into hard building 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, slabs, sintered tiles, marble, granite, concrete, and glass. The diameter of 30 mm indicates the size of the hole that will be created after drilling, so choose the diameter according to the pipe or element that will pass through the hole. The core drill is intended for dry drilling, without the need to add water. It is suitable for water pipe passages, holes for taps, fittings, and cable glands, and will be useful for tilers, plumbers, and DIY enthusiasts during bathroom or kitchen renovations.

  • Diameter – 30 mm.
  • M10 Thread – attachment directly to the angle grinder with M10 spindle thread.
  • Soldered Diamond – diamond grains firmly bonded to the tool body throughout the cutting part.
  • Dry Drilling – drilling without water; cooling with water may extend tool life.
  • Chip Removal – two longitudinal cutouts in the casing for the removal of drilled material.
  • Materials – ceramic tiles, slabs, sintered tiles, marble, granite, concrete, and glass.
  • Colour – black.
  • Contents of Package – 1 piece of 30 mm diamond core drill bit.

When starting to drill, 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 core 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 core 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 core bit is securely tightened on the spindle and that the grinder runs without vibrations and wobbling. During prolonged drilling, take short breaks, or you may cool the cutting part with water, which will extend the tool's life. Use protective goggles, gloves, and a respirator, as fine dust is generated during dry drilling.

The 30 mm diamond core 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 create passages for water pipes, holes for taps, fittings, and cable glands. The attachment to the angle grinder M10 is quick, and the core bit can be easily replaced with another diameter. The tool is compact, making it easy to store in a toolbox, so it is always at 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.
