The RUBI DRYGRES 4DRILL Diamond Drill Bit Kit is designed for dry drilling in porcelain stoneware, ceramic tile, natural stone, and artificial stone using standard cordless drills. Its diamond cutting edges support clean, controlled hole drilling across dense surface materials without requiring water during operation.
Each drill bit features a hex shank connection for direct compatibility with common battery-powered drills. The included storage case keeps the drill bits organized and protected, while the multiple size options cover common installation and fixture mounting applications.
