How to use
Install the bit into a compatible rotary hammer with an SDS+ chuck, ensuring the shank locks securely. Select the hammer drilling mode and apply steady, even pressure without forcing the bit. Allow the tool and carbide tip to do the work; withdraw the bit periodically to clear debris and prevent overheating. For deeper holes, remove dust from the hole regularly to maintain drilling efficiency.
Usage recommendations
Use appropriate personal protective equipment such as safety goggles, hearing protection and dust mask. Match the drill speed and hammer power to the material being drilled; reduce feed pressure when encountering reinforcement or very hard stone. Store the bit dry and protected from impacts to preserve the carbide tip.
