Diamond drill bits include many types of drilling tools, such as electroplated diamond dilling bits, metal bonded diamond or CBN drilling bit or core drill bits.
If you would like to drill through hard materials such as Glass, Stone, pebbles, Precious and Semi-Precious stones, Ceramic, Tile, Glazed Pottery, Shell, Bone or Fossils, then you will need to use a diamond drill bit. We offer a complete range for use with your rotary tool. Diamond Core Drills allow good circulation of water and will stay cooler whilst drilling. A core drill will cut more quickly than a solid drill since it is only cutting out a small circle of material.
Kemei produce and aim on different types of grinding tools, such as aluminum oxide grinding wheel, silicon carbide grinding wheels, mounted points, Diamond Grinding Wheels, CBN Grinding Wheels and wheel dressers.
