Bosch EXPERT HEX-9 Hard Ceramic Tile Drill Bit - 7 x 90mm

No, the Bosch EXPERT HEX-9 Hard Ceramic Drill Bit is designed for rotary action only. Using a hammer drill setting can damage the bit and the tile.

No, one of the key benefits of the HEX-9 is its ability to perform dry drilling without the need for any lubricant or cooling.

This bit can drill comfortably in tiles up to a hardness of PEI 5.

The EXPERT HEX-9 is designed to last up to 10 times longer than a standard ceramic drill bit when drilling hard tiles.

The HEX-9 shank is designed for a strong connection in both standard three-jaw chucks and 1/4" internal hex tool holders.

While designed for hard ceramics, it is not specifically optimized for glass. For glass, a specialized glass drill bit is recommended.

Yes, the Bosch EXPERT HEX-9 is available in a range of sizes and multipack sets, though this guide specifically covers the 7 x 90mm variant.

Ensure the drill is set to the correct speed and that you are applying firm, consistent pressure. Check that the bit is compatible with the tile hardness (PEI 5 maximum).

Ensure a precise start by holding the drill steady and applying light pressure initially. The multi-faceted tip is designed to prevent skidding once it engages.

While designed for dry drilling, avoid prolonged, continuous drilling in a single spot without brief pauses. Allow the bit and material to cool slightly if necessary, though this bit is engineered to minimize heat issues.

Verify you are drilling into materials within its specified hardness range (up to PEI 5). Ensure proper drilling technique is used and the bit is securely seated in the chuck.
