FAQs

What is the maximum drill bit size for concrete?

The maximum recommended drill diameter for concrete with hammer drill bits is 45mm. For breakthrough drilling, it can handle up to 80mm, and with core cutters, up to 125mm.

What type of accessories does this hammer use?

This rotary hammer uses the SDS-max accessory system for secure and efficient bit changes.

Can this tool be used for light-duty drilling?

While capable, the GBH 8-45 D is designed for heavy-duty tasks. For lighter applications, a smaller hammer drill or standard drill might be more suitable and easier to handle.

How often should I clean the tool?

It's recommended to clean the ventilation slots after each use or when significant dust build-up occurs. Keep the overall tool clean and dry for optimal performance and longevity.

What does 'impact energy' refer to?

Impact energy (measured in Joules) indicates the force each hammer blow delivers. Higher Joules mean more power to break apart hard materials like concrete and stone.

Is dust extraction compatible?

Yes, the Bosch GBH 8-45 D is compatible with various Bosch dust extraction attachments, which are highly recommended for professional use to maintain air quality and visibility.

What is the weight of the tool?

The tool weighs 8.2kg, which is substantial and designed for stability during heavy-duty operations.

Troubleshooting

Tool does not start

Check if the power cord is securely plugged into a functioning outlet. Ensure the switch is in the 'on' position and that restart protection has not been activated. If the problem persists, contact customer support.

Reduced drilling/chiseling power

Verify that the correct SDS-max bit is installed and properly seated. Check for any blockages in the ventilation slots or at the bit tip. Ensure the tool is not overheating; allow it to cool if necessary.

Excessive vibration

Ensure you are using the correct accessory for the task and that it is not damaged or bent. Check for proper bit seating. Significant vibration beyond normal operation might indicate internal wear and require professional inspection.

Mode selector is difficult to turn

Ensure the tool is not under load and the chuck is clean. If it remains stiff, avoid forcing it and seek professional service.

  • Durable construction with metal components.
  • Suitable for a wide range of SDS-max drilling and chiseling tasks.
  • Advanced safety features like restart protection and rotation control clutch.

Setup, Compatibility & Care

Setup: Ensure the tool is unplugged before inserting or removing accessories. Insert the SDS-max bit firmly until it locks into place. Select the appropriate operating mode (drilling, hammer drilling, or chiseling) using the mode selector switch.

Compatibility: This rotary hammer uses the SDS-max accessory system. Ensure all drill bits, chisels, and core cutters are SDS-max compatible. The tool is also compatible with various Bosch dust extraction attachments, recommended for maintaining a clean work environment and user safety.

Care: Keep the tool clean and dry. Regularly check the ventilation slots for dust and debris and clean them with compressed air. Store the tool in its original case in a dry, secure location. Periodically inspect the power cord for damage. For maintenance, always refer to the user manual or consult a qualified service center.
