negative:
- No speed control:
when you press the power button is located immediately to full speed and maximum force; This makes it virtually impossible to drill small holes precisely (4mm or 5mm drill) in a concrete wall; even with a 6mm drill you have very very careful; the hammer comes with such a force that the drill is immediately deformed like a chewing gum; Have an external power regulator for outlet hung between them and set at about 30% capacity -> thus were precise holes with a 5mm drill in a concrete wall with no problem; this would hammer a built-in power regulator I would rated it with 5 stars;
- The supplied drill eggs a bit and the smallest drill has 8mm in diameter; a little too much if you want to hang only one picture; but here you realize already that this hammer drill is intended for coarser; the purchase of a higher quality drill set is recommended;
- The hammer is relatively heavy and large
Conclusion:
for that price you get a very strong and robust hammer drill; for people who really want more smaller holes (for pictures and furniture fixing) drilling into concrete walls, this rotary hammer without additional (unfortunately expensive, from 60, - Euro upwards) power controller unusable;
People who order the basement large holes (from 8mm up) want to drill or to pierce a concrete wall can be accessed from quiet. The hammer drill marches with great ease in the concrete and has thereby no troubles
