Bosch CYL-9 Ceramic Tile Drill Bit - 7 x 80mm

No, this bit is specifically designed for use *without* the impact function. Using it with impact can damage the bit and the tile.

This bit is suitable for soft to medium-hard ceramic tiles. It may also be used on non-tempered glass.

No, the CYL-9 Soft Ceramic Tile Drill Bit is designed for dry drilling and does not require lubrication.

It is recommended to use low speeds for drilling with this bit to ensure optimal performance and longevity.

After the bit has cooled, wipe it clean with a dry cloth or a soft brush to remove dust and debris.

The bit has a cylindrical shank, making it compatible with standard drill chucks on non-impact drills.

While it can work on some softer porcelain tiles, it is primarily optimized for ceramic. For very hard porcelain, a specialized bit may be more effective.

Ensure the drill is set to a low speed and the impact function is OFF. Verify you are not attempting to drill into a tile that is too hard for this bit. Apply steady, even pressure without forcing.

Reduce drilling speed further. Ensure the drill bit is sharp. Try starting the hole with a very light pressure to create a pilot indentation before applying more force.

Immediately stop drilling and allow the bit to cool down. Ensure you are using the correct low speed setting and not applying excessive pressure. Consider briefly withdrawing the bit from the hole to clear dust and aid cooling.
