M20 X 620mm SDS-max-9 Bosch Speed Clean Hollow Bit 2 608 576 295

The 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 shanks and works in combination with industrial M-class vacuum cleaners.
