Overview
Diamond Core Drill Bit 40 mm with M10 Thread for Angle Grinder Soldered Diamond Black Dry Drilling for Tiles, Marble, Granite and Glass

The diamond core drill bit with a diameter of 40 mm is designed for drilling holes into hard construction 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 soldered diamond grains, which can handle ceramic tiles, slabs, sintered tiles, marble, granite, concrete, and glass. The diameter of 40 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 bit is intended for dry drilling, without the need to add water. It is suitable for pipe, waste, and tap or fitting openings, and will be used by tilers, plumbers, and DIY enthusiasts during bathroom or kitchen renovations.

  • Diameter – 40 mm.
  • M10 Thread – attachment directly to the angle grinder with M10 spindle thread.
  • Soldered Diamond – diamond grains firmly bonded to the tool body across the entire cutting area.
  • Dry Drilling – drilling without water; cooling with water can extend the lifespan.
  • Chip Removal – two longitudinal cut-outs in the casing for the removal of drilled material.
  • Materials – ceramic tiles, slabs, sintered tiles, marble, granite, concrete and glass.
  • Colour – black.
  • Package Contents – 1 piece of 40 mm diamond core drill bit.

When drilling, hold the grinder at an angle of approximately 45 degrees initially 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 slight 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 can 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 40 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 openings for pipes, waste, and taps or fittings. The attachment to angle grinder M10 is quick, and the core bit can easily be replaced with another diameter. The tool is compact, making it easy to store in a toolbox, ensuring it is always 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.
