Diamond Core Bit
A core bit, a specialised drilling tool, creates cylindrical holes or “cores” in various materials like concrete, masonry, stone, and asphalt. It consists of a hollow, cylindrical tube with diamond-embedded segments at its cutting edge. As the core bit rotates and applies downward pressure, it grinds away the material, creating a clean and precise hole.
Core bits are used in construction industries, requiring accurate and efficient hole drilling. With over two decades of manufacturing experience, Roschen designs core bits for light and heavy-duty drilling, offering premium quality laser-welded diamond segments that provide optimal drilling speeds and maximum performance. Wet cutting methods are recommended to increase cutting speed and tool life and eliminate hazardous dust, such as silicosis.
