With the Carat Brilliant ETDB008000, you drill accurately through hard ceramic tiles, porcelain stoneware, and natural stone without water cooling. The built-in Lubriwax core melts progressively during rotary drilling to keep the diamond tip lubricated and cooled, eliminating wet mess during indoor installations. Featuring an 8 mm diameter and a 35 mm length, this dry diamond drill bit is ideal for mounting bathroom fixtures, grab bars, and accessories. Its 1/4" hex shank fits securely into standard rotary drills and cordless drill drivers without slipping, preventing cracks and ensuring neat, professional results with complete control.
