In many ways, the development of dust is a critical factor on building sites: dust is a health hazard to users that creates significant costs. Inserting chemical wall plugs also requires clean bore holes that are free from dust. To reduce dust propagation, protect users' health and save working time, Heller provides a perfect solution for dust-free drilling: the Duster Expert.
The Duster Expert hollow drill bit lets users drill and clean the hole in a single step. All you need to do is connect a conventional builders' vacuum cleaner to the drill to allow dust to be extracted directly at the bore hole where it develops and not when it has already escaped into the environment. This eradicates a large part of the dust pollution to considerably improve users' health protection. The Duster Expert is flexible and universally suitable for any hammer drill.
