Bosch EXPERT HEX-9 TCT Drill Bit - 12 x 250mm

This EXPERT HEX-9 TCT Drill Bit is designed for use on a wide range of materials including concrete, brick, soft tile, wood, granite, and metal.

The Hex shank provides a strong, secure connection in the drill chuck, maximizing torque transmission and reducing the likelihood of slippage compared to round shanks.

Centering Geometry ensures a precise and accurate start to your drilling, preventing the bit from wandering or skidding on the material surface.

Yes, the EXPERT HEX-9 TCT Drill Bit is designed to be versatile and can be used effectively with impact drivers, as well as rotary drill drivers and screwdrivers.

Clean the bit after each use to remove debris, store it in a dry place, and avoid overheating. Inspect regularly for wear and replace when necessary.

Yes, the optimized carbide and advanced geometric design make it suitable for drilling into hard materials such as granite.

TCT refers to the Tungsten Carbide Tip, which is significantly harder and more durable than standard steel, allowing the bit to penetrate and withstand abrasion from hard materials.

Ensure the centering geometry is properly engaged at the start. Use a center punch for initial marking on metal or hard surfaces. Verify the drill is set to the correct speed for the material.

Confirm the drill is set to the hammer drill function (if available) and that the Hex shank is securely tightened in the chuck. Apply consistent pressure and allow the drill's percussion to work.

Ensure you are using appropriate speeds and feed rates for different materials. Avoid excessive force or overheating, as this can degrade the carbide tip. Clean the bit regularly.

Ensure the Hex shank is fully inserted and the chuck is tightened securely. Check that the drill chuck is clean and free of debris. If using a standard keyed chuck, ensure it's adequately tightened.
