The reason for buying was because I was looking for somebody to drill 5 holes of 100mm through a wall that is 40cm thick. The quote on this was 70€ per hole. So I went online and bought this one I am more than happy that I did so.
Great money for value. It has enough power, the drill bit can cut through 5 - 6 mm of steel rebar. Drilled through 5 holes so far I believe it can do a lot more.
