Bosch EXPERT HEX-9 Multi-Construction TCT Drill Bit - 6.5 x 100mm

Its primary advantage is its versatility, allowing you to drill accurately into a wide range of materials, from hard granite and concrete to wood and metal, with a single bit, preventing the need to switch tools.

Yes, it is compatible with most standard drills that have a three-jaw chuck or a ¼" internal hex tool holder.

Use impact mode when drilling into hard, brittle materials like concrete and stone. Use rotary mode for softer materials such as wood, soft tiles, brick, sheet metal, and plastic.

It helps to keep the bit firmly in place on the material surface, preventing skidding and ensuring that the drill starts exactly where you intend it to.

While highly versatile, this bit is optimized for a broad range. It may not be the most efficient choice for very specific applications like drilling extremely hard metals (e.g., hardened steel) or very soft woods where specialized bits might offer better performance.

The bit is constructed from optimized carbide using a fine grinding manufacturing technique, designed for durability and a long lifespan when used appropriately for the material and drilling mode.

TCT stands for Tungsten Carbide Tipped, indicating that the cutting edges of the bit are tipped with a very hard material (tungsten carbide) for enhanced durability and performance on tough materials.

Ensure the drill is set to impact mode (if applicable for the material) and that the drill is operating at an appropriate speed. Check if the material is harder than expected or if the bit is dull.

Ensure the material is clean and flat. Apply firm, steady pressure and ensure the drill's centering geometry is properly engaged with the surface. If drilling into very smooth surfaces, consider scoring the surface lightly first.

Reduce drilling pressure and speed. Allow the bit to cool down. For deep holes, periodically withdraw the bit to clear debris and cool the hole. Ensure you are using the correct mode for the material.

Ensure the hex shank is fully inserted into the chuck or holder. Tighten the chuck securely. Check the chuck or holder for any damage or wear.
