Although this is not the model for professionals is a drill very good range and not a first prize. This is a drill which has three positions and two directions of rotation. We can therefore also be used to screw and unscrew (low speed pos1) even if it is not advisable because it is too powerful and will not stop spinning automatically and would be too heavy but it's possible . It therefore has a classic position for drilling of wood, plaster, brick, tiled floor. A drill-percussion position to pierce the concrete to use so when the classic position is not effective. And a position only percussion for which there is no rotation therefore drilling but blows as if tapped with a hammer and chisel. Except that it is more accurate because the moves are regular. You can take off the floor tiles of the wall for example. The drill comes in a sturdy plastic storage case. It comes with bits SDS is one of strands fixing system which "clipped" and "déclipsent" in a second. No chuck tighten. But if you have classic locks that you have to use the drill comes with a conventional chuck to grip him that "snaps" on the SDS drill. So very good product.
