How to use

Choose the appropriate diameter bit for the required pilot hole. Secure the bit in the drill or compatible rotary hammer chuck, ensuring the HEX-9 shank is fully engaged. Position the tip at the desired drilling point and start at low speed to ensure correct centering, then increase speed as needed. Apply steady, moderate pressure and avoid excessive force to prevent chipping. No lubricant or cooling is required for dry drilling in ceramic tiles.

Usage recommendations

Wear appropriate eye and hand protection. Test on a spare tile to confirm feed rate and speed. For best results, use a drill with adjustable speed and a stable work setup; avoid prolonged continuous drilling to allow the bit to cool between holes.
