Bosch EXPERT HEX-9 Multi Construction TCT Drill Bit - 7 x 150mm

Its primary advantage is its versatility, allowing you to drill accurately into a wide range of materials including concrete, brick, tile, wood, granite, and metal with a single bit.

The bit features a hex shank, making it compatible with most drills, especially impact drivers and rotary drill drivers. Ensure your drill's chuck can securely grip the hex shank.

Impact mode is recommended for hard materials like concrete and stone, providing hammering action. Rotary mode is suitable for softer materials such as wood, plastic, and soft tiles.

The centering geometry ensures the drill bit starts precisely where you intend without skidding, leading to more accurate hole placement, especially on smooth or hard surfaces.

Yes, the EXPERT HEX-9 is designed to drill into sheet metal and other metals, in addition to masonry, wood, and tile.

The bit is made from optimized carbide using a fine grinding manufacturing technique, designed for durability and extended life across various challenging materials.

This particular model is 7mm in diameter and has a working length of 150mm (overall length approximately 150mm, but the scope of delivery mentions 7 x 90 x 150mm, implying 7mm diameter, 90mm flute length, and 150mm overall length).

Ensure the centering geometry is properly engaged with the material before starting. Use a center punch to create a small indentation if necessary. Confirm you are using the correct drilling mode (rotary or impact) for the material.

Make sure the drill is set to 'impact' mode. Ensure the drill bit is properly seated in the chuck. Check if the carbide tip shows signs of significant wear; if so, the bit may need replacement.

Ensure the drill chuck is tightened securely around the hex shank. Some drill chucks are better suited for hex shanks than others; verify your chuck is designed for optimal grip on hex shanks.

Reduce drilling pressure and allow the bit to cool periodically. Ensure you are using the correct speed setting on your drill for the material. Drilling dry into some materials like masonry can generate heat; consider using water for cooling if appropriate for the material and application.
