How to use
Select the drill bit diameter that matches the required hole. When drilling tiles and hard ceramics, use a steady, controlled drilling speed and apply light to moderate pressure to avoid cracking. Use a guide or template when precise positioning is needed. Continuous or intermittent water cooling is recommended to prevent overheating and extend bit life. Secure the workpiece and follow general safety precautions such as eye protection and appropriate masks when creating dust.
Usage recommendations
For best results when working with porcelain and glazed tiles, use the appropriate drill guide and apply water cooling. Begin drilling at a low speed to create a starting groove, then increase speed gradually while maintaining cooling. Match the bit size to the fixture or anchor being installed to ensure clean edges and accurate holes.
