Bosch EXPERT HEX-9 Multi-Construction TCT Drill Bit - 5 x 100mm

This versatile bit is designed for granite, concrete, brick, soft tile, wood, and metal. It can also be used on sheet metal and plastic.

Yes, the hex shank ensures a strong connection and maximum torque transfer, making it ideal for use in impact drivers, especially for concrete and stone (in impact mode).

The bit features a sharp tip and advanced geometric design that helps to stabilize the bit on the surface, preventing it from wandering or skidding as you begin drilling.

Rotary mode is for softer materials like wood and metal. Impact mode, with the hammer action of the drill, is used for harder materials like concrete and stone to break them up more effectively.

Centering Geometry helps the bit to start drilling precisely at the marked point, reducing the chance of the bit wandering off-center, leading to more accurate hole placement.

The lifespan of the bit depends on the materials being drilled and the usage intensity. Its optimized carbide construction and fine grinding manufacturing technique are designed for durability and extended performance compared to standard bits.

This refers to a drill bit with a 5mm diameter, a 50mm working length (flute length), and a 100mm overall length.

Ensure the tip is sharp and undamaged. Use the Bosch Centering Geometry feature to initiate the hole. For very hard materials, consider using a dedicated masonry bit if skidding persists.

Verify you are using the correct drilling mode (rotary or impact). Ensure the bit is correctly seated in the chuck and that sufficient torque is being applied. Clear debris from the hole periodically. Check if the bit is becoming excessively hot, which may indicate dullness or excessive force.

Reduce drilling pressure and allow the bit to cool periodically. Ensure you are not exceeding recommended speed settings for the material. The bit might be nearing the end of its lifespan and may need replacement.

Ensure the tool holder is clean and free of debris. Check that the hex shank of the drill bit is fully inserted and that the tool's chuck or collet is tightened securely. If the shank is damaged, replace the drill bit.
