How to use
Choose an appropriate drill with hammer function for masonry when required, secure the bit in the chuck and set the drilling mode according to the material. Mark the drilling position, start at low speed to center the bit, then increase speed and apply consistent pressure until the required depth is reached. Clear dust from the hole periodically to maintain cutting efficiency and prevent jamming.
Usage recommendations
Wear appropriate personal protective equipment such as eye protection, hearing protection and dust mask when drilling masonry. Use a depth stop or tape on the bit to control drilling depth, and allow the drill and bit to cool between extended drilling cycles to avoid overheating. For reinforced concrete or very hard natural stone, consider using a dedicated carbide-tipped or SDS-plus bit matched to the drill type.
