Bosch Expert HEX-9 Multi Construction Drill Bit - 7.00 mm

It can drill into concrete, stone (using impact mode), brick, soft ceramic tile, sheet metal, wood, and plastic (using rotary mode).

Yes, the hex shank is designed for excellent torque transmission and is ideal for use in impact drivers and drills in rotary mode or impact mode (for masonry).

It helps to keep the drill bit precisely on the mark, preventing it from wandering and ensuring accurate hole placement, especially when starting a hole.

Use impact mode for hard materials like concrete and stone. Use rotary mode for softer materials such as wood, plastic, metal, and tile.

This particular drill bit measures 7mm in diameter, with a 60mm flute length and a 100mm overall length.

The hex shank provides a more secure grip in the drill chuck compared to a round shank, preventing slippage and ensuring maximum power transfer, especially under high torque.

Yes, it is suitable for drilling soft ceramic tiles in rotary mode. For harder tiles, a specialized tile bit might be recommended.

Ensure the drill is set to 'Impact' or 'Hammer' mode. Apply firm, consistent pressure. Check if the bit is worn or damaged.

Verify that the chuck is tightened securely around the hex shank. Ensure the hex shank is clean and free of debris. Use a drill designed for hex shank bits if possible.

Reduce drilling speed and apply less pressure. Allow the bit and drill to cool periodically. Ensure you are using the correct drill mode for the material.

Ensure you are using the 'Rotary' setting for non-masonry materials. Start with a pilot hole if needed. Check that the drill bit is not bent and the chuck is centered.
