Good Cheap hammer

After the holes drilling proved by a concrete slab for laying network cables from the basement to the ground floor with a hammer drill as lengthy torture, I tried a SDS Plus Rotary Hammer it this time. The choice fell on the Berlan 1500 Watt SDS hammer drill incl. Drills & chisels due to the good price / Leisungs ratio. The unit is compared to others in this price range quite heavy, makes a very robust impression and reminded me strongly of a Hilti when I held it for the first time in his hand. For the intended purpose it's almost too bad, because 16mmx52cm-holes are so ruckzuck drilled through concrete, where it naturally suitable drill are also required, but it is also conveniently located in the Amazon Marketplace are. The durability of the hammer I can therefore make no experiential statement, but my impression is that you can also carry out extensive work easily with the hammer.
Too bad I can only find something that you can only use SDS Plus drill with the device and not even normal twist drills, which are indeed often with many different diameters has been. A hammer drill, the hammer therefore not replaced, which would also have limited due to the weight possible.
