The fischer SDS adapter with internal thread M8 allows for the attachment of fischer cleaning brushes for concrete in conjunction with approved borehole cleaning. Advantages: The BS steel brushes with bristles made of stainless steel are approved for cleaning boreholes in concrete and masonry. Depending on the required cleaning method, the brushes can be used either mechanically or manually with the included handle. Caution: Before use, check whether the brushes still have the required diameter. They must create a noticeable resistance when inserted into the borehole. Brushes that are too small should no longer be used. Applications: Cleaning of boreholes. Materials: Suitable for borehole cleaning in all solid and hollow building materials. Functionality: The cleaning brushes are inserted into the borehole, and the borehole is cleaned either mechanically or by hand using a rotational motion while simultaneously moving the brush back and forth.
