Bosch Drill Bit Set - EXPERT HEX-9 Multi Construction

These bits are designed for a wide range of materials including concrete, stone, brick, soft ceramic tile, sheet metal, wood, and plastics.

While they work in standard chucks, they are optimized for drills with both rotary and impact functions, as you'll need to switch between modes for different materials.

The Bosch Centering Geometry helps the bit start accurately without wandering. Ensure the bit is securely in the chuck and the drill is set to the appropriate mode.

The Hex shank provides a strong, non-slip connection to the drill chuck, allowing for maximum torque transfer and better control.

Clean off dust and debris after each use and store them in a dry place, ideally in their original packaging or a bit organizer to prevent damage.

Yes, these bits are suitable for drilling through sheet metal. Ensure you use them in rotary mode and consider using a cutting lubricant for smoother performance and extended bit life.

The set includes five bits with sizes: 5.5 x 60 x 100 mm, 6 x 60 x 100 mm (two bits), 7 x 60 x 100 mm, and 8 x 50 x 100 mm.

Ensure the Hex shank is fully inserted and the chuck is tightened securely. Check if the chuck jaws are clean and free of debris. Ensure you are using a compatible chuck type.

Verify you are using the correct mode (rotary vs. impact) for the material. Reduce pressure, allow the bit to cool, and ensure the drill is operating at an appropriate speed.

Ensure the drill bit is securely seated in the chuck. For very hard materials, a pilot hole may be beneficial. Check for any damage or bending on the bit's tip.

Confirm the drill is set to 'Impact' mode and that the impact function is active. Apply steady, firm pressure and allow the drill's hammering action to work.
