Tips

For best results, use a rotary hammer drill with sufficient power and set the mode to hammer drilling. Apply steady pressure without forcing the bit; let the tool do the work. Periodically withdraw the bit to clear debris from the hole, especially in deep drilling. Always wear appropriate safety gear, including eye protection and hearing protection.
