This is a useful tool. I used it in a concrete masonry wall with a new Milwaukee fuel-powered wet/dry vacuum and a Milwaukee 2804-20 impact drill to drill a few holes and I was impressed with how clean the hole was without a drop of dust on the bottom, the only one Disadvantage of this tool is that it falls down when you are about to finish the hole and you hit the brush with the drill chuck as it requires very little force. he will move from his place. ______________________ I will update this review after using it together with sds plus and max.
