This hammer drill has surprised me doich very positive. For the price you think yes, that can not be anything good. But far from it. The drill is very quiet and smooth. It has an easily changeable right / left running, and a hammer function. The chuck is a keyless chuck, it does not require a key. The speed is continuously adjustable via a dial on / off switch. This can not even my Skil hammer drill for about 90th In delivery included are still a depth stop and a sturdy handle, which is mounted at the front, see picture. Even when drilling scores the machine. Concrete walls I could easily pierce (with the corresponding drills of course). The machine is quite easy and therefore very handy. Who reliable but low price product with hammer drill function searches in the household, which is well served by the Einhell. 5 stars for a product with an excellent price-performance ratio.
