Bosch Expert 3 Piece HEX-9 Hard Ceramic 10x Longer Hard Ceramic Porcelain Tile Drill Bit Set

The Bosch Expert HEX-9 Hard Ceramic Drill Bit Set is a professional 3-piece tile drilling set designed for dry-drilling hard ceramic and porcelain tiles, lasting up to 10x longer than a standard Bosch CYL-9 soft ceramic drill bit.

As wall tiles continue to increase in size and hardness, the demands placed on tile drill bits have grown significantly. Bosch developed the Expert Hard Ceramic Drill Bit specifically to meet this challenge, using Carbide Technology — one of the hardest metals available — integrated into the tip through precision fine grinding manufacturing techniques.

The advanced multi-faceted tip design distributes the workload across multiple asymmetric faces, making it highly effective in hard materials. The specially designed centring tip ensures an accurate, controlled start, preventing skidding and scratching on expensive tiling surfaces — a critical advantage when working on porcelain or large-format ceramic tiles.

No lubricant or cooling is required during use, making these drill bits practical and efficient on site. The HEX-9 hex shank ensures a secure connection and maximum torque transmission in both three-jaw chucks and ¼" internal hex tool holders.

This set is ideal for tilers, plumbers, and contractors drilling into hard ceramic wall tiles, porcelain floor tiles, and similar hard tile materials where standard tile bits would wear prematurely.
