The SDS plus-9 Speed Clean enables dust-free drilling. During operation, the built-in vacuum attachment draws dust through extraction openings in the drill bit, allowing for optimal material removal without additional steps. This technology ensures a clean, dust-free working environment. The drill bit is suitable for use in masonry, concrete, and reinforced concrete. The SDS plus-9 Speed Clean drill bit is available as a 4-cutter for larger diameters and as a 2-cutter for smaller diameters. It features a precise centering tip. To achieve accurate results, the wear indicator shows whether the hole diameter is still within the tolerance for the anchors. It is manufactured in Germany.
