Bosch SDS Speed Clean Hollow Bits

Bosch SDS Plus-9 and SDS Max-9 Speed Clean Drill Bit allows for dustless drilling. While working, the built-in vacuum attachment pulls dust through extraction holes in the drill bit, allowing optimum material removal without additional steps. This technology results in a clean, dust-free working environment. The bit is intended for use on masonry, concrete and reinforced concrete. It is compatible with rotary hammers with SDS Max / Plus shanks and works in combination with industrial M-class vacuum cleaners.
