I sanded all the joints of my Shower out, not a single tile has gone about to break. It has of course taken a few hours but the HM segment saw blade is properly gone through, so that I can actually use it even further. The machine is great in the hand, can be operated easily and the discs can be easily adjusted with a short loosening the screw to come in the last corner.
To change a disk loosening the screw completely replaced the wheel and screw it tightly. It's that simple.
Even the wooden blade I used to cut various boards and am so impressed by the machine that I am gone to the search in the house, what I could do more.
