  • Abrasive drill bit
    Patent number: 6981911
    Abstract: An abrasive drill bit and method of use on glass, ceramics, tile, stone and similar solid materials, both natural and synthetic. A circle is ground into the material using a cylindrical drill bit, which grinds a loose abrasive between the bit cylinder and the material. When the circle is complete, a punch-out piece of the material falls out, leaving a smooth hole. Alternatively, the loose abrasive is ground between a solid bit and the material to grind out a hole. In both methods, the loose abrasive is preferably mixed with water to form a slurry.
