Bosch Expert HEX-9 Multi Construction Drill Bit - 12 x 150mm

It is designed for granite, concrete, brick, soft tile, wood, and metal.

Yes, it is compatible with rotary drill drivers and impact drivers. For concrete and stone, use impact mode; for other materials like wood or metal, use rotary mode.

The HEX shank provides a stronger connection to the drill chuck and ensures maximum torque transmission, leading to more efficient and secure drilling.

The advanced geometric centering design ensures the bit starts exactly where you intend, preventing the bit from skidding across the surface and improving accuracy, especially on hard or smooth materials.

It is designed for soft tiles. For extremely hard porcelain or ceramic tiles, a specialized tile or glass bit might be more appropriate, although this bit can handle softer varieties.

It offers up to 5x more precision than a standard Bosch CYL-3 Drill Bit due to its optimized carbide construction, fine grinding, and advanced centering tip design.

The dimensions are 12mm in diameter, with a 90mm working length and a 150mm overall length.

Ensure the drill is set to the correct mode (impact for concrete/stone, rotary for others). Check that the bit is sharp and free from debris. Apply steady pressure without excessive force.

Ensure the material surface is clean and flat. Use a center punch to create a starting dimple. Ensure the HEX shank is properly seated in the drill chuck.

Allow the bit and workpiece to cool periodically. Use a cutting fluid or lubricant for metal drilling. Ensure correct rotational speed is used for the material.
