How to use
Install the drill bit into an SDS+ rotary hammer according to the tool manufacturer's instructions until it locks. Use the appropriate hammer drilling mode for concrete and stone. Begin drilling at low pressure to establish the hole center, then apply consistent axial force while letting the tool do the work. Periodically withdraw the bit to clear dust and check progress when drilling deep holes.
Usage recommendations
Use appropriate personal protective equipment (eye protection, dust mask, hearing protection and gloves). For reinforced concrete, verify reinforcement location before drilling. For prolonged drilling sessions, allow intermittent cooling pauses to prolong bit life and maintain drilling efficiency.
