How to use

Fit the drill bit into the SDS-plus chuck of a compatible rotary hammer following the tool manufacturer's instructions, ensuring the bit locks securely. Select appropriate drilling mode (hammer or hammer+rotation as required) and set correct speed and feed pressure for masonry or concrete. Start drilling at low speed to position the bit, then increase to recommended operating speed while maintaining firm control of the tool. Withdraw the bit occasionally to clear dust for efficient progress and to avoid overheating. Inspect the bit after use and clean dust from the flutes before storage.

Recommendations for use

Use suitable personal protective equipment including eye protection, hearing protection and dust mask when drilling masonry or concrete. Match drill diameter and length to the anchor or fixture being installed and use a vacuum or dust extraction where possible to reduce airborne dust. Replace the bit if the cutting edges become worn or if drilling performance degrades.
