Bosch EXPERT HEX-9 Hard Ceramic Tile Drill Bit - 6 x 90mm

The EXPERT HEX-9 is specifically designed for hard ceramics and tiles. While it might drill glass, it's not optimized for it and may chip the edges. For glass, specialized glass drill bits are recommended.

No, a standard drill with a three-jaw chuck will work. However, using a drill with a ¼" internal hex tool holder or an impact driver will allow for better torque transmission and potentially faster drilling.

The EXPERT HEX-9 can last up to 10 times longer than a standard ceramic bit when drilling hard tiles. Actual lifespan depends on the tile hardness, drilling technique, and number of holes drilled.

The EXPERT HEX-9 is designed for *hard* ceramics (up to PEI 5) and utilizes Bosch Carbide Technology for extreme durability. Soft ceramic bits are for less dense, softer tiles and will wear out very quickly on hard materials.

Yes, this bit is specifically engineered for dry drilling of hard ceramics. However, always wear appropriate safety glasses and a dust mask, as drilling will produce fine dust.

A medium speed setting on your drill is generally recommended. Avoid extremely high speeds, which can lead to overheating, and avoid very low speeds, which can reduce efficiency.

Ensure you are starting the drill at a very low speed. Use a center punch or a piece of tape to mark the exact drilling spot for a more stable start. Verify the multi-faceted tip is engaged correctly with the surface.

Check if the drill is set to the correct speed (medium speed is often optimal). Ensure the bit is not dulling significantly; if so, it may need replacement. Apply consistent, moderate pressure; excessive force can slow progress.

While designed for dry drilling, prolonged drilling in very hard materials can generate heat. Allow the bit to cool periodically. Ensure adequate ventilation around the drilling area.
