The Black & Decker BCK21S2S-QW Combiset consists of the Black & Decker BDCHD18 impact drill and the Black & Decker BDCIM18N impact screwdriver. This allows you to drill in heavy material such as tiles and stone and you also screw with long and thick screws. Thanks to the battery operation, you simply do jobs in places without an electrical outlet nearby. Both tools have built-in LED lighting, making it easy to work even in dark places. After use, neatly store the impact screwdriver and impact drill in the supplied soft bag.
